The LONGEST DRIVER I have EVER tested! Part 2 

Thanks so much. I’m 69 and a solid golfer with a little bit of hand arthritis. I bought the jumbo max xl, put it on my driver and worked with it on the range. I fight the hook when I go after driver and often will block it right when trying to prevent the hook. I play a Callaway Epic Speed driver and have played two rounds with this gripon the club and have hit 27/28 fairways dead center and missed one a few feet into the left rough. I got accustomed to the feel immediately and my hands feel great. I hit the ball a little higher so I dropped loft to 9.5 from 10.5 . I am hitting everything dead straight and long and I will next place them on my wedges and short irons and hope I continue to hit it as straight. They are a game changer. The cost is irrelevant as they are a few dollars more per grip but a new ball is $4 when it gets hooked into the woods!. The big problem is fitting 14 of these clubs in my current bag with the xl grips!

Honest to god the JumboMax ha completely revolutionised my game. I’ve got early onset of arthritis in my left hand pinky (RH golfer) and I’ve struggled like mad for a couple of years with my grip, never getting grip size or grip quite right. Thought I’d give these a go, firstly in my driver, and now every club - the release of tension by not feeling like I need to strangle the life out of the club has added a good club’s distance to every club (around 10-12 yards) and 20 yards of carry with my driver. Took a bit of getting used to. It now feels better than any ‘normal’ grip I’ve used and I can’t see me ever going back!

Tested their tapered grip and the straight tech grip and preferred the non tapered grip. The butt end is a little smaller diameter with less taper and allows you to grip down on the club with a similar feel for short game shots. Definitely get the lite versions if you get them. Lighter than Golf Pride jumbo size grips and similar to standard size grip weights so no change in swing weight.

I’ve been using the Medium jumbo max for a few yrs and will never go back. No extra distance but consistency is fantastic

I was entertaining the idea of larger grips. I am 60 and I find that with standard size grips, after a good practice session on the range, my hands ache a bit. I currently have a couple extra wraps on my PXG irons and it does help with the ache over my older clubs. Thanks...look forward to these on irons!

Andy.... Fitted a Jumbomax in a Medium to my Mavrik Driver and WOW!!! I took 2 or 3 swings to get used to it but after that I was nailing it. You feel like you have more control with the larger diameter grip and it seems to inspire confidence. What I noticed... Dispersion was great, carry height was consistent and hard to tell with range balls but I'd say I was averaging about 15-20 yards additional carry distance and that was achieved consistently. Very impressed so far and have ordered more. Give it a try folks.... Who'd have thunk a much larger grip could make such a difference.... Cos it does 😁

Cheers Andy, I'm going to wait for you verdict on the 5 wood findings and consider giving the larger grip a try on driver. 👍

The smile and look on your face at 4:51 when you looked at the launch monitor for that 256 carry with 285 total says it all. Good stuff!

Fantastic video Andy. Thanks for doing this. I actual have been testing a jumbo medium on my 7 iron as of last week and I swear its going 3 to 5 yards farther carry. I also like the feel better. I use to think it was just a gimmick but after my test and your video I am sold on the jumbo grips. Thanks again!

I recently changed my woods and wedges from std Tour Velvet grips to mid-sized GP MCC Plus4 grips. Even that change took some getting used to but the 'quietening' of the hands, especially the trail hand was noticeable as is the reduction in hand fatigue. Experiment completed and deemed a success, I was about to change all the irons over too but after Pete Finch and now you trying these Jumbo Max, I might hold off and give these a go. Cheers.

I recently changed to the jumbo grip because of arthritic issues and was totally surprised by the distance and dispersion improvement. Like you said I am not sure of the science behind it but the results were great!

Great stuff Andy...just thinking, does the grip weigh different to your standard, and so changing the clubs swingweight, which may make a difference?

TXG did a test on over sized grips. I recall they found that the larger grip slowed the rate of club face closure, which is great if you tend to over draw your hybrids for example. I tried it on one of my hybrids and it seemed to work. I know that if I use that club it won't go left much. It would be no good to me with my driver though. I leave it out right too often.

I have had it on my driver for a while and love it. I am older now 75 and just find it easy to hit. But it may take you a while to get used to it. Once you do you wont change. Period. I will regrip the rest of my clubs this week and will give you some more feed back. You will not be hitting in your fingers but rather your palms as the grip is so big. I find it easy to do this and so did the greatest golfer in the history of the game. Jack Nicklaus. Now thats a great endorsement.

Enjoying this series of your videos on Jumbo Grips. How have those grips changed the swing weight? Are the heavier than the standard grips? Lighter? Curious..

Thanks so much for these video's around the jumbo grip, now you have started something I've got to give it a go! cheers.....

Andy, I switched to CP2 midsize grips. Started on my wedges. Then had them put on all my clubs in the bag. Haven't looked back since. I recently ordered some pre-owned Callaway Epic max woods and the regular grips on those felt like gripping a pencil. Had them regripped with midsize on those. Bad swings are still bad swings but i'd say the midsize grips hit the ball straighter overall.

"GO JUMBO" Andy you know it makes sense lol

Replacing a std grip with a jumbo also affects the clubs swing weight due to the weight of the grip! Unless other alterations are made to the club head /shaft length etc, the club should feel/swing lighter maybe adding a bit of club head speed and added distance. Just my thought.

Very interesting!! Waiting for the next results! I have thought about this also…. And maybe it is that you don’t have that much pressure in the hands. Like a tennisracket it’s big and you can hold it easily.

Great video. Please keep us informed as to how your further testing goes as this is very intriguing. I do know Peter Finch is using them on his new clubs. May need a bigger bag to fit them into mind.

This is timely as I plan to purchase a new driver in the near future. This will make me think of a larger grip. I would like to see a comparison of balls best suited to low swing speed. Which compression is best. Thank you.

Awesome Andy. I'm on my way right now to the golf store... to have that Jumbo grip put on my driver!

I switched to them for accuracy (I tend to hook it), and it works for that. I first put them on the driver, 3 wood, sand wedge and lob wedge. Have to start tracking distance, since I just switched to them on everything else. Hopefully I don’t fly too many greens.

I use jumbomax lite grips on woods amazing so lite, and comfortable definitely improved my driving

For me, it just feels more comfortable. I feel like I have more control of the club head. It doesn't feel like the club is twisting in my hands as much.

Well Andy, Golf Pride needs to thank you cause I just ordered 2 new Jumbo grips because of this video!! Thanks

I went from a regular size grip on my driver shaft to a mid size, and find no additional carry. Don't think the size if my hands can handle a jumbo grip!! Any idea's why I'm not getting the extra yards carry that you did?

I think this is down to things you identified - not gripping as hard - slowing the time the club gets to the ball and this results in a higher launch angle I have a feeling it will all go back to “normal “ once you got used to it

It appears the grip could be affecting your spin rate? That seams to be the key factor as you were sub 2000 and you launched it 100ft peak. I would focus the data points on the spin and launch & attack angle. And this also proves that Club head speed will not always produce the best yardage.

Like you I did not expect these results. I use 2 drivers over the course of the season. Definitely gonna put one of these JumboMax grips on the driver I use in the spring. Not sure why you get the better results but they can't be ignored.

Good work Andy. I tried the Jumbomax ultra lite grip on my driver for the first time this week. Took a little getting used to but the results were much better the expected. Not sure if there was an increase in distance due to windy conditions but it was certainly straighter than I normal hit with the driver. Less movement in the air and definitely couldn’t go left which is my normal bad shot. Over drawing or pull. The driver height was possibly higher than normal which for me is a good thing. Going to stick with it and possibly try the bigger grip in the 3 and 5 woods. Carry on the good work and enjoy the content 👍🏌️‍♂️

Makes sense. I don't have large hands. I went to a midsize grip + 4 grip. I feel more confident with it. Regular grips feel small and I tend to hook with them. I can really let loose with the larger grip and put some power behind the club that I might have been holding back.

I put the large jumbo max on all my clubs. The driver is 10 yards longer and with a much tighter dispersion. My fairway wood and hybrid feel better and I’m hitting it much more consistently the irons I don’t see that big a difference but it seems to be more consistent. On my wedges I feel more confident because I think it keeps the face square, less rotation. My theory on the distance and consistency is that it relaxes the hands. If your hands are relaxed your arms are relaxed your shoulders are relaxed can you generate a better turn in consequently more whip through the strike zone.

Golf grips are only contacting and effecting hand position and pressure. These make players feel a lot more confident as it's a bit like gripping and swinging a baseball bat. As long as your swing is sound, the accuracy and direction should be similar to regular grips. If anything, these will promote a slight fade/slice for a right hander. Loved the joyful face when you launched it 250 + :)

They feel good, but 2 me they slow my release down? I have trouble squaring the face up using the very large grips! I put one on my Ping G425 Max and left EVERTHING out 2 the right with way 2 much spin! So , I replaced the large grips with a Golf Pride Tour velvet 360 midsize which is almost a small standard size grip. Results were day and night! Longer, straighter, and with much less spin!

Andy what glove size do you use, if you go on website it says different grip sizes ie med glove get small jumbo max etc

I'd give my left, you know what, to hit my drives 250 yds. I'm a bit older than you but still strong and athletic so not sure what I am doing wrong and I have a decent swing. Same for all my clubs really - and I have the Jumbo grips which I love. I have a new GC3 coming from Foresight and setting up a temporary indoor range in my dinning room - yes my dinning room. I am no longer married so I am setting up a mini simulation room until next summer when I can build my addition on the house and make proper one. Anyway, looking forward to getting some data and taking some picture with V1 to nail down where I am missing. BTW I like what you did with the interior of your space and am looking to do something similar. I know you filmed the build so I need to check it out again. Love you channel mate !!

I just put a medium Jumbo Max on my drier. The jury is still out as I only have one round under my belt and the driving range was closed. I like that it feels like you don't have to grip the club much at all

Great video, i debated over the Jumbo's (pricey) and the leather Grip Master grips (went with GM) but i will buy a few of the Jumbo's to try as i use the Single plane swing for injury issues (less back pain) , looking forward to the next video.

Great video can see you had alot of fun with this and that you where happier with using your own driver . Looking forward to the next video with 7 and 5 wood

Looking forward to see results w the rest of the bag! Definitely tempting to try or on a driver

I changed to jumbo grips on irons and woods . Not sure any science behind it but it felt more comfortable, my hands are small and interestingly ladies clubs have thin grips ! So not sure what to make of it really other than i prefer the feel of the thicker grip . This applied to squash and tennis rackets too but again I assumed it was just personal preference rather than “science “. Love to know if it does lead to longer distance.

I actually tried it myself. I put about another 15 yards onto my driver in range testing. I tend to pull the ball a little bit more but other than that the difference is quite noticeable. It has eliminated that death grip I tend to put on my clubs. I just put them on my 3w and 3h and will see how they work. Might do the whole set if this keeps up.

Just had a indoor lesson tonight and switched driver shaft in my ping driver to a shaft with jumbo grip. Everything went more positive. Club head speed, launch angle and most importantly carry of average 12-15 yards. So much so I left my driver for re-gripping, pick it up tomorrow. My Pro concluded much the same as you. Leap of faith but I can always get the old grip put back if needs be.

Once i weakened my left hand grip no pain and still great distance Hitting a draw now as opposed to my usual left to right I think maybe need to experiment with grip as adjust size certainly cant use my old grip

The jumbo grips have completely changed my game. Those ✋ pull shots have almost disappeared. I've gained 10+ yards pure club. And I'm think that's because I'm flushing the ball better

Andy can you tell me where you got you’re jumbo max grips . Cheers

Great follow up.....love the info

Can you show a close up of your left hand on the grip to give me an idea the what the separation of your finger tips. I really want to give a try, but am not sure what size grip is right for my short fingers.

Jumbo grips + baseball grip = golf is fun. Never going back to tiny grips and awkward hand placement. Im 6'5 and these grips changed everything.

I put a Winn oversize less taper grip on my Epic Flash Sub Zero and didn't see any obvious benefit. In fact, the driver has been benched in favour of my old Nike Covert. However, I will take both of them out tomorrow and try to do a comparison.

I picked up three JumboMax JMX Ultralite Golf Grips from ebay. Overall I think they suck! They are overpriced to start. They are difficult to install. When putting on steel shafts, the edge of the shaft easily tears them up. I got one on my graphite drive with quite a bit of effort (I've installed grips for many years). With the other two I was able to get one on my 6 iron and one on my lobe wedge, but with damage. With my driver, I now have two idential drivers with different grips. After hitting 25 shots with each driver at the range, no meaningful difference in distance or dispersion. But what really sucked was the hard surface on the grips. I got no relief in grip pressure, rather the opposite. My other grips are Winn DRI-TAC. There is a huge difference in the feel of the two grips. The Winn's are far superior. I haven't given up on oversize grips. I have some Jumbo DRI-TACs ordered. They aren't as oversized as the JumboMax, but I won't have to grip them as tight either.

I have Jumbo grips on all of my clubs, I feel I don't need to grip as hard which in turn keeps my forearms & shoulders more relaxed.

i am interested in trying the Jumbomax grip but i am unsure which size to try. How did you determine the large size was best for you? great video, very informative.

Great channel and great delivery.

Tempo tempo tempo,I’ve said it before,it improves your tempo. Whether it’s because you feel more & you want to give yourself more time through the ball I don’t know? If it works only for that it’s worth trying?

Grip size made a massive difference to me as it kept me in a more neutral grip adding 10-20 yards on all clubs - I use midsize with 3 wraps so they are thicker & firmer

Hello Andy, could it be the swing weight? You've put a heavy grip on the same shaft and club head as the standard grip. The balance point would have moved closer to your hands. It might make the clubhead feel lighter. Just a thought.

I put the JMax medium grips on all of my clubs including the wedges. Gained about five yards throughout the set. Biggest thing is accuracy. I will never go back to pencil grips! Starting to worry about how fast my hcp is dropping.

I wonder if it could be adjusting your trail hand grip (making it more neutral) which could be giving you a better strike…? Might be worth looking at how neutral your grip is when using your normal driver with the thinner grip.

After watching both videos and getting some new clubs last week , I went to my local pro / repair shop I changed my grip from a single tape to 3 tapes on my cobra radspeed could not get the grips in the video , at the range tonight hitting 40 balls with the driver what I did notice was 1. I did not hit the ball left, 2. I only hit a few right ( last week I was hitting both pushes and pulls), 3. I found the ball to be straighter and a higher flight. I will see how my 12 holes of golf go this week and will consider getting all my clubs changed too the 3 wraps of tape , oh my h-cap is 8.6

Proof is in the Pudding, the larger grip may make the hands more neutral so they do don't over react in the swing, much like when you chip and keep the hands out of the swing, will be wait ing to see your results with the 7 iron and 5 wood.

Dudes, it's easy to know why- it increases your confidence because your hands are full with max grips. As such it helps to also hit it straighter, For example have you ever seen an wood chopping ax with a skinny grip, they all have fat shafts/grips. If it were skinny shaft you'd have no accuracy whatsoever. So, yes for average golfers like 98% us are the big grips will be very helpful. But if you are a scratch golfer i don't think the grip will do anything much for you because you have already mastered the game of golf.

Great video Andy, how wou.d these grips impact on finesse iron shots.

Great video as always. But why do you need to figure it out? It works better for you so you should use it. Who cares what the reason is. I have found with the Jumbo max grips lots of people try to talk themself out of using them. Yes they look different on the clubs but if they work that much better then what you are currently using why would you not use them. I went to them a few years back because I have a bad wrist. They have helped that issue. I hit the ball much straighter and did gain some distance. Now when I try a regular grip it feels so tiny! I will never go back.

Hi Andy, I have just swapped normal grips with 2 layers of tape underneath for a midsized grip with 3 layers . This has helped with reducing the hook. It feels so much more comfortable and gives me the confidence to just hit the ball without fighting the club. Results are straighter and longer drives. I'll watch the other vlogs with a big interest.

After 2 years are you still using the jumbo grips 😅

Do you recommend doing the irons aswell ? Or wait and see concerned about feel on the irons if not done .

New grips for the new year for sure. At least for the long clubs. I have mid size grips on the irons, and they will probably stay there..........but look out woods.

I feel an experiment coming on… 🤣

This is quite interesting? How does the jumbo grip relate to hand size? Would someone with a small/medium size hand be able to use this grip?

No way!! Another gimmick to suck me in with promises of gains and consistency!! Looks promising though. If I had the tools at home to do it myself then I would definitely have a go as my driver could do with another grip. Maybe it's worth getting a jumbo grip on there and trialing it for a couple of months, got plenty of pro shop credit to burn anyway!!

It’s a much lighter grip so swinweight will have gone way up so more mass in the head.

Here's my bet - the bigger grip is preventing excess the face rotation which increases the energy transfer into the ball, In effect you are compressing the ball better. In other words a hammer hitting a nail at a glancing angle does not hit the nail as hard as a square hit.

Maybe it's easier to grip the club, so grip pressure reduces? Looks like it's worth testing.

Curious how it affects your grip? If you use strong or weak grip? Does your hand wrap around grip? I know Bryson uses a different swing plane where the grip goes through palm.

So does the jumbo grip add a couple grams to the butt of the club making the head “feel” lighter and giving you a little extra club head speed???

Could be counterbalance effect moving weight further up the shaft

Could the large grip cause you to be more aggressive when turning the hands over and thus creating a little more ball speed?

also I found that the grip didn't kill the hands it delays them for better smash factor numbers

I think it's been mentioned already Andy but it's physics. You've increased the total club weight while reducing the club swing weight. As a result you're delivering greater mass at a higher speed and as long as your smash factor remains the same you'll arrive at greater ball speed and more distance.

Maybe it's grip pressure not being as close to shaft or works the same as a fishing pole or gripping a baseball bat at fat end would feel lighter and faster.

My driver feels more comfortable held in my palms , I’m going to give this a go Andy. 👍

You look very relaxed when you swing now compared to earlier videos, now put one on your 7 iron and enjoy the control of the ball.

I would like to know if these shafts were stock length, or 1" shorter like you have been testing?

Andy: Can you confirm the grip and size you used. Was it the Ultra light? Which grip size? I thought you said you used an XL in the 1st video but a large in this video?

I need new grips Andy, will wait and see the next video before making my mind up!

here my results: had a few irons regripped (6,9, and 4 ) they inadvertently put midsize on the 4. Feels good, but the inconsistent action doesn't help . The point is , keep them consistent. same swing 14 clubs.......why mix the grips only to add another variable ?

I’ve always heard that oversized grips cause a fade, have you found that to be true?

Larger surface area definitely helps...

Try these on some irons, and see if you get a difference on them as well.

What did it do to your swingweight?

Do you play these large grips a year later?

where the best place to get the jumbomax utralite grip Andy

Like you honest opinion of all clubs. Thanks

Nice video, I might give them a go myself 👌🏻

Hi it may be suiting the size of your hands ??

I’ve put a golf pride jumbo grip on my driver, not for distance but dispersion, I like it!

With your swing speed I think you would love the new Krank formula 11X
