Hi flybub, I have the same pap as you as well, 5 1/2 over and 1/2 inch up and I have 3 balls drilled with pin under, two with pins 4 1/2 from pap and one 5 inches from pap right under ring. The one with the pin 5 from pap makes my track kind of close to my fingers and thumb, but it still works. I also have another ball with the pin 5 1/4 from pap pin under that makes my track close to thumb and fingers but still works. But like a few other posters have said, putting the pin at like 4 - 5 1/2 from pap above the fingers is a better idea. Also, just like what insidedrive said, doing a 4 1/2 or 4 by 4 1/2 gives a very nice mid lane read and nice continuous back end. I have a storm blaze with a 4 1/2 x 4 1/2 pin up and it has a really nice reaction, plus the track is like 1/4 inch from my thumb and fingers.
