I am a high tracker myself and have drilled balls for other high trackers as well. A good drilling for us, is the pin above the fingers but shifted just outside the ring finger which should put the pin around 4 3/4 from your axis. Kick the cg outside the grip line about an inch and a half. That should be just far enough to require a SMALL weight hole. I emphasize small, simply because a high track will automatically get the ball to flare and read the midlane enough so that "flare increasing" holes are not necessary. In fact, you have enough rev rate where you may not ever need a flare increasing weight hole. A large weight hole will only get the ball to read the lane that much faster and create that weaker backend reaction or even a roll out effect.
What you are going to want, are bowling balls with rg in the lower 2.5 range. With your PAP, I think balls that have 2.46 type RGs unless you really push the ball through the heads, the ball is going to rev so fast that the ball may roll out on the backend. I believe that you may be better off finding balls with higher diff numbers (.05 - .06) than lower RGs.
Shawn,
I believe that the reason your balls are clipping the thumb hole, is that they are not drilled strong enough. As a high track, you are going to clip the thumb hole. The trick, is to lay out the ball so that you get the ball flaring at a quicker rate to get the flare rings off the thumb hole as quickly as possible. You would benefit from having layouts where the pin and cg are shifted just outside the grip with a small weight hole. As I mentioned before, high track players are already going to create higher flare potential, so I usually recommend layouts in the 4 3/8 - 5 range pin to PAP and the sooner you want the breakpoint, the farther out you kick the cg. Keep in mind though, that the farther you kick the cg, the larger weight hole that will be required to get the side weight out. What kind of layout do you have on your Action and Pyro?
