Title: Drilling Layout discussion
Post by: Jesse James on December 30, 2017, 10:56:23 AM
I had a discussion with one of my good bowling friends, who also happens to be a ball driller as well. He knows I'm a geek for this stuff so he presents a newly drilled piece he has and ask me, "what will this ball do for you?"

It's a Radical Cash, drilled pin under his middle finger with the mb kicked out. The surface is at 4000.

So I say for me, it would give me relatively good length; it would read the mids a little earlier, but it would have a smooth transition on the backends.

He says NO! He says, the pin-down drilling would raise the RG of the ball, and lower the differential, especially because of the surface.

Now to me.....I think we are saying the same thing, just using different terms. Is this a correct perception?

P.S. (he had just gotten back from a bowling seminar)

All relative. Depends on the pin to pap,  your bowling style, and  the conditions thrown on. 

All lucky guesses until you throw the actual ball.

Also this sentence doesn't make sense, think it's missing something.

Think about it like this. 50% of ball reaction is based on surface. 25% is the pin-pap distance. 15% is the core strength, 10% is layout/tweaks. Surface dictates the length of the ball, pin distance is how much flare you will get, core strength is the engine size, high pin vs low pin has much debate, but simply its how fast the ball will transition, high pin will react faster and a little longer down the lane, lower pin will transition slower and a little bit earlier.
Check out some great information here. Mitch is super knowledgeable

 There are no cut and dry answers to that question. I have seen balls drilled that “fit” two separate bowlers. One guy throws it, and it’s smooth and consistent. The other guy throws it, and it’s longer and stronger off the spot.

 For me, the drilling you described would puke it’s guts out early, roll forward, and do very little on the backend. That’s what every asymm I’ve ever drilled like that (or similarly) did.

 The only asymm’s I've ever drilled that worked consistently over a range of conditions either had the mb WAY past the val, or right in the thumbhole, NEVER in a “strong” position.

Cash is a strong assym, so the pin further from the pap will increase flare.

As far as the surface having anything to do with lowering the diff and raising the rg...

No.

Thanks for all the input! Good stuff right here!

+1 on it depending on your style.  For example you could put virtually any layout on a Cash and with my style (high axis tilt, low revs, speed dominant) I could make it work it on fresh house shot no problem (sadly too weak may require me to throw from right corner).  For say some of the 2 handed rev monsters the opposite where regardless of layout or surface they might not be able to keep it on the lane or keep it from burning up even on the heaviest flood (strongest ball for a reason).
