Driver Fitting for Negative Angle of Attack 

No problem Stephen. Hope this helps guide you towards some solutions.

Mav SZ and Sim max both seemed to be best for me. My club path and face angle with MAV SZ on avg was -.7 and -.2. While with Sim max is was .4 and -.3 on avg. Also hit the g410 but those numbers seemed to deviate more.

I have a terrible forward shaft lean at address causing a negative angle of attack and high strikes off the face with a tendency to sky it. I use a Cobra F8 with Evenflow blue stiff and only hit it 240-260 while I carry my 7 iron 175. The best I’ve ever hit a driver is my old Cobra SZ400 with a Saber Tour Vector 75....wish I could get back to that swing and a similar shaft.

Lots of factors possible: could be the head design of the driver you're using, or the amount of ball speed you're producing, contact point, etc. Unlikely that too positive an angle would cause excess spin, generally those that hit up on the driver are lower spin players.

We're planning to rent a proper high speed camera in the future that eliminates that distortion and would show how the shaft is actually bending. That combined with the Gears system we have coming will let us show some pretty cool stuff!

110 swing speed = approx. 162 ball speed. @ 17 Degrees launch and 2100rpm spin is 282 carry according to Flightscope's Online Launch monitor - flightscope.com/products/trajectory-optimizer/ To get your current 260 carry with that club head speed with a little fade, you are in the zone of ( 10 Degrees launch, 4400rpms spin)

Fancy :)

Just wish there was somewhere I could fart around on a Launch Monitor to "crunch" the numbers. I could go to golf galaxy, but I don't trust the big box stores

They will definitely give you some useful feedback and you should go and do it and see if the 10Degree launch and 4000spin is the zone you are hitting it - my guess is that it is as that is exactly what I use to do - I have an M2 with a Haz Black 6.5 cut to 44.5" driver. I hit the range for 5 days and worked very hard on trying to see if I could develop a new style driver swing (I have also been to TXG as they are local to me for a gapping session and a practice session to see what I was doing). It took me a few days on the range to figure out for me how to do this because it is very different. I tee the ball high, I had to really learn how to hit from in to out, keep my head back - and when you hit it like this it is extremely obvious on the range because for me my carry went from a trap fade like yours at 245-250 yard carry to a couple yard high knuckleball draw at 270-275 - just like in Matt & Ian's previous video. It took me 5 days to re-build my alignment setup so I knew where to ball would be starting and finishing, and I can still lose one right, but it definitely flies way further.

Yeah, when its a wide open fairway on a par 5 and I want to let one rip I tee it about a half a ball higher than normal(normal for be is about 1 ball high) AND hit the big high draw...This used to be my stock shot but as I've begun to play more tournament golf I've had to find a fairway finder shot and that's what I have now. When I hit the "Rory Mac" high Draw I carry it about 280 and most definitely rolls out better too.

Would be worth checking out your numbers Alex, but sounds like you would benefit from either less loft or a driver with a more forward CG location.

Yes need to get round to doing that! Currently got a ping G25 10.5. It’s at its - setting but I’m not sure that makes much difference.

djjazzyjeff123 a few people have told me that, I’d just like to see to go lower and more penetrating. My 3W can go the same distance with a totally different flight! I just want the Driver to do the same. I think some time on a monitor required

Hoping to get our installation of Gears booked for the next few months, we want to have the creator of the system visit us for the installation and film some videos with him so that may push our scheduling back a bit.

He's not longer than Rose. I have both of there TM numbers, like I said Adam is slightly more neg on his AOA than Rosey. Delivered loft is part of spin loft, they are not separate entities. Spin Loft, Impact Location and CG are the primary factors at play here.

I understand that delivered loft is part of spin loft, my point is Matt can control what loft he desires through ability. Allot of club golfers that produce a negative AoA are more to the extreme -4/-5 and they can not instinctively alter this. A video that best illustrates this is one of your own on hitting up on the driver. Change the AoA to a reasonable compromise and a fitted driver will produce even more gains.

9º in the Ping, and 10.5º in the others

10.5º

Yup for sure, shaft lean is a factor as well in determining dynamic loft

AOA isn't the whole story Judah it's the topic. There are way more variables being taken into account here than the title suggests. Our aim here though is to give a little help to the guys and gals that are a little steep. By showing them how to balance AOA, Dy Loft and impact location you can still maximize your output. Appreciate you thinking about he topic in such detail, it only helps others to understand the factors involved.

I know this is an old video and such but I struggle with a lower AOA at - 1.5 working on getting to 0 (sometimes) but I'm extremely spinny 3200 but when I do get those 2500 I carry close to 300 or more with 122 ch. Tried so much to get spin down....

Not yet but something we can do in the future

😆

It is really neat to see this exact type of result. It sort of allows 'everyone' who doesn't want to change their 3wood teed up swing (2 degrees negative angle of attack / trap draw type approach) to still benefit. I wish I would have know this because after I watched your last video, I went out and spent 5 days at the range figuring out my New Modern Hit 5 Degrees up on the Ball Driver Swing (and I did gain at least 20 yards carry so thank you). It would have been far easier to throw money at the TXG Old Man Cobra Illegal Driver Swing and just walked out like a champ with 20 extra yards. Vote for golf cheating video of the year award.

-1 on trackman would be pretty close to level on GC Quad

Rear CG would launch and spin more than forward CG. Tiger is likely increasing the loft and moving the weights forward to get more launch angle via the loft, while keeping the spin low via the weights, probably with the goal of hitting it a bit farther.

Thanks for your reply. So all things being equal, a 10* rear CG is not equal to a 10* forward CG head for launch or spin. So in that case would a 11* forward CG be equal to the 10* rear CG in as far as launch is concerned, as well as having close to the same spin?

Yes to the first part. For the second, you would use that 11º head to raise the launch angle with loft, but the forward CG would ideally keep the spin down as low even potentially lower than the 10º rear CG head. All theory of course, more in this video as well in case you missed it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NIfTAA8D_eY.html

Thanks I'll have a watch of the video.

Look at Ping's offering for a forgiving driving iron: ping.com/clubs/crossovers/g400

HAHAHA!!!! Air Titleist cruising at an altitude of 32,000ft!!

Ian Fraser It might not be the most efficient ball flight but it sure does impress the old folks on the course when they see a ball fly above head height 😂

Possibly if you had very high launch and very low spin

isnt he hitting -0.5 degree?
