Good info. Mo Pinel has been preaching this ever since the rule change was announced. Luckily I just got back into bowling and had everything drill without a weight hole. But, now layouts are very important to ball motion as to where you could change the motion with the balance hole.
hi ron can you please answer why myself and may other players that i drill for have had the same thingso when i use to drill balls before the new rules to find out where we wanted the hole put we would throw the ball for a little bit and see how we wanted to manipulate the reaction. we have always found the total boards covered of the ball to be similar with the side weight in it.... HOWEVER the way it rolls front to back and the way it hits the pins is much different and seems a lot weaker testing this myself with a few different balls even before they were thinking of the rule. IQ Tour Nano for example was one that I had punched up and it wat pretty close to the 2.5 ounce side weight so it required a hole, again this is when the rule wasn't in place. Threw it and it hit like a sponge and I just couldn't get the ball to fit my eye but after the hole I found that it was quicker, cleaner and it was much less lazy off the spot and god I loved that ball I have seen heaps of videos of how it doesn't make a difference where it is on the drilled ball but Im defiantly I realise that 2.5 ounces is a bit drastic but if it doesn't matter why everyone that has tested this that I know have a similar outlook on the way it changes ball motion.just wondering if you have seen this from anyone
What causes a different CG distance on different balls? If the weight block is in the same relative place ball to ball, how is there a different amount of mass elsewhere in the ball to move the CG around?
You said we have 3oz. How can I have a asymmetric Astro Physics drilled to hit hard with a L shape? Right hand 55yr. guy. Thank you Ronald. Wonderful video...
I have been bowling for about 3 years and with some mentoring from a friend with a 232 average. I am finally joining a league. I bowl between 160 and 180 constantly and I may be not releasing my ball correctly. I am throwing at the 10 board and getting a good pocket hook and leave the 10 standing all the time. I have a90% 10 pin conversion, but I'll miss the 7. I am right handed.. My problem is; I am told to move 3, 6, 9 boards on spares and throw at my same mark. I am twisting my wrist when I release. Should I or should I throw straight and let the ball do the rest? I roll a Rhino, a Bedlam and a DV8. The DV8.
What if the mass bias on an asymmetrical ball is closer to your thumb or farther away from your thumb where you drill the thumb does that change the reaction
This video makes me extremely nervous about my C System 2.5 Absolute beast of a ball when the conditions are right for it,drilled pin down with a bias hole... Last night this thing was ripping in at huge angles Is this ball going to be ruined with a plugged hole?
It's actually the opposite. Before the rule change with the weight holes, they could just leave it with no weight hole and some side weight where they could drill a weight hole to make it react different than without one. All they can really do is change the surface now, which doesn't do as much as a weight hole can.
@@drivillain4967 Well what I meant was now the pro shop worker will not have to do any work mentally as far as figuring out where to drill that fourth hole.
WOW, really informative and awesome video!! What about people that don't use their thumb, is that hole not allowed anymore since weight holes are not allowed anymore?
You would need to use less aggressive cover stocks to allow your ball to skid longer and not hook early. Slower ball speeds need milder covers unless you are on long heavy oil patterns then an aggressive cover can be used.
I would like to make two points with respect to this topic. First, even though static weights are now of little importance due to the rule change, it is still worth noting that the farther the pin is away from the center of gravity, the more imbalanced the core is (I'm speaking specifically about symmetrical cores). Imagine a ball cut in half on a pin out ball, say 4" as an example, if you measure the distance between the edge of the core and the outer shell at the half way point (half way between the top and bottom of the cut away ball) the core will be closer to one side than the other. In a pin-in ball the core will be much closer to being exactly in the middle of the ball. Secondly, I would like to point out that this rule has to be among the dumbest things I've ever heard of in my life. If there has ever been a better example of "locking the barn doors after the horses ran away" than this rule, I am not aware of it. I would love to hear what the rationale was behind this because I sincerely cannot imagine how a convincing argument could be made to take this step at this point in time. Had someone suggested this rule 20 years ago it would have made a lot more sense.
Yes - even with asymmetricals , the "Pin Out" distances between Pin and C/G DOES H A V E an effect .. .. How much and/or how reverent AND which one does what better is the only issue left to discuss .. ..
I just got a new symmetrical Motiv Top Thrill ball and I want it drilled correctly. My pro shop never asked me about my PAP and just drilled my previous balls however just according to my finger span. I kind of learned by watching your videos and others that this approach is dead wrong. I want a stronger ball layout but how can I get my new ball drilled the right way when all my other balls have been drilled not knowing my PAP? I'm very confused as to how to know where to drill my finger holes in a symmetrical ball if the only spot I have to go by is the Pin. If there are no holes in the ball for me to throw it how can I know where my PAP is?
The PAP comes from the bowler not the ball. In fact if it is measured correctly it doesn't matter what ball you use. You should either talk to your PSO and have him find your PAP or look for one that will. We have plenty of videos on layouts too.
Jose Ramonit Gatilogo you’re right in that symmetric balls have less drilling options since the MB will always be on the thumb. The CG still won’t matter though, you just pick where the pin should be and place the CG anywhere you want on the ball within legal limits. The reaction will be the same with all CG placements if the pin is in the same relative position to the thumbhole.
thing i haven't read is why is this rule change important? I don't have a preference as we've drilled balls for decades before the idea of weight holes became mainstream. So why and why now? These questions are really just rhetorical as it's done deal.
USBC research shows these changes will: Slow oil pattern transition Cause bowlers to move less Keep the same scoring pace with lower oil volume No current USBC approved balls will be deemed illegal. All equipment is grandfathered in, indefinitely. Balance holes need to be plugged by August 1, 2020. The goal IS to protect the playing environment for the future, NOT to lower scoring. 1.Why did USBC eliminate the balance hole? Balance holes were originally intended to correct a ball that was drilled outside of our static weight tolerances. However, in recent years, balance holes have become a tool for pro shop professionals to manipulate the balls. Our studies determined the balance hole can greatly increase the Differential RG to strengthen the reaction of the equipment beyond the ball’s original design intent. 2. What is the intended purpose of a balance hole? Balance holes were intended to help correct the static imbalance so that the ball would comply with USBC’s one-ounce rule for finger, thumb or side weight, and three-ounce rule for top or bottom weight. 3. How important is finger, thumb or side weight? The static imbalance rule has been in place for decades, dating to before reactive resin. As bowling balls evolved, the coverstock has been cited in the 2008 ball motion study as having the most impact on performance of bowling balls, while side weight had minimal impact and the impact of finger and thumb was on the low end of the spectrum.
As Ron mentioned, drilling a weight hole at the depth required will almost always change the diff's of the core in the bowling ball. This has led some more savvy shops into being able to change the dynamics of a ball by changing the core.
Ronald Hickland Jr but, for no thumb bowlers it would matter correct? Because isn’t the thumb the PSA on a symmetrical ball (with no weight hole) and the only way to find the PSA on a ball with no thumb is 6-3/4” from the pin through the CG?
So now just drill a symmetrical core ball with the pin, CG and thumbhole inline on a neutral layout. Why is my guy still offsetting the cg on symmetrical core balls like it's 2018 if it doesn't matter?
Brother Ron, I think your wrong in your language...... According to MO RICH himself, and his articles.. AYSIMS have a large track flare from 2 -3/4 to 6-1/4 inch....you just said a pin distance from 5-6 would hook less... Completely agree if that was a symmetrical ball BUT we are looking at asymmetrical ball here. Are we saying this because of the change in static weights and no motion holes being allowed now?
Ok Ron my bad you said 5-6, BUT still Asymmetricals won't have less track flare with large pin distance... Symmetrical will have less track flare I know with 5-6 in pin to pap distance.
We have done that from the beginning, and will continue to do so. I can respect your opinion and I'm sure you can respect ours too. Watching our content is completely optional. We appreciate the feedback.
How do you know what everyone else knows?? This may be someone's first time watching one of his videos.. Every video you make should be the same intro because you never know if this is someone's first time seeing your video, if you don't like the intro then you can always fast forward or just not watch 🤷🏿♂️.. Peace ✌🏿
