PIN to PAP
« on: July 07, 2018, 07:53:12 AM »
Iím learning more about dual angle drilling. I have a good grasp of the drill and VAL angles. Where I donít follow is the PIN to PAP number. I know if the Pin is closer to the PAP will decrease flare but so will a larger number like a 5Ē PIN to PAP (symmetric).
So doesnít flare affect the amount of hook? More flare equals more surface touching the lane, right? So if you didnít want a sharp breakpoint which way should the pin be placed?
For a smooth ball motion which of the following would be best?
70 x 3 3/8 x 70
70 x 1 Ĺ x 70
70 x 5 x 70

Depends upon your own unique actual PAP measurement, and the type of shape you are looking for out of the ball also considering actual lane conditions.

Of the examples listed, the 3 3/8 would flare more and may be a more rounded shape down the whole lane, front to back, the 1 1/2 would be earlier rolling and smoother, and the 5 would be latest response to friction.


On a THS may not be able to see too much difference, would be seen more readily on Sport or PBA patterns.


Just my opinion.

Most cases, generally speaking without know your game. You would go with the smaller pin to pap, like a 2" pin to pap would do the trick.

I typically have success with 3-4" pin to pap layouts.. so drill was rolls best for me and utilize differ covers and cores to get the reaction I want.

For a smoother reaction, the pin closer to pap. For less flare but more down lane motion, the pin further away. For max flare (which doesn't always equate to Max backend), 3 3/8.

To add one thing, in my experience don't be so focused on the dual angle measurements.

Pin-PaP is a larger factor along with cover and surface prep

Excellent point. Don't get to concerned with layouts

I have this from a former gold coach

Influences on ball motion:
50% - surface prep
25% - pin-pap distance
15% - core strength
10% - layouts/tweaks

Which is why I agree with whoever previously said to find a layout that works for him and change surface/covers and core to change your arsenal.

Far too easy to stress about layouts when especially on symmetric balls the only thing that really matters is pin to pap and doesn't matter as much as one would think.  Only took a few unnecessary re-drills for me to catch on.  Even on asyms its easy to lose any layout changes in the noise of inconsistency for most bowlers especially strokers imo.
