This is a long story, but I really need some advice....

I started my girlfriend using finger tip a few months ago. She rolls the ball quite well, however, as soon as the ball breaks, it starts to roll onto it's thumb. Now, I thought she might be full rolling it, but When I looked at her track in the oil, It starts about an inch from her fingers and goes about 1/4 from the thumb, then you see a dry track going farther out from the fingers, say 2 inches crossing the thumb hole. I went to my driller, and he said it was a problem with her release, and that the static weights do not affect the track.

The ball has a one inch pin, located under the ring finger. The CG is right at the midline slight right of the center of span. She is a righty.

The ball she throws is a hot rod hybrid. The ball really does well for her, its just rolling onto the thumbhole at the break point. We have tried different releases, and every time, it goes onto the thumb at the breakpoint.

I started thinking about this, and I was wondering, if what he said was true, than why do I have three different balls, all symmetrical with different tracks. One of my balls has a good bit of finger weight, and it tracks out farther from the fingers, and the other two balls track closer to the fingers.
The balls that track closer to the fingers have 1 inch pins, the ball that tracks away from the fingers has a 3 and 5 inch pin. all three ball have the same RG, between 2.50 and 2.52.


Is there anything my proshop guy can do for her?

If what he said was true, why do some balls track differently? Is it all relative to pin position?
