I have been playing with the pitches in my thumb for about a year now. I feel like I am getting close to that "perfect" feel, but sometimes the ball comes off my thumb just a little too early resulting in much less rotation and a flat shot.  I am trying to have the most relaxed grip possible.  I went from 3/4 reverse 3/4 under to 1/4 reverse 1/8 under. 4.5" span both with tight holes.  The original pitch resulted in more rotation but more grip pressure and muscling, the latter less muscle but less rotation.  My question is should I keep the 1/4 reverse and add more under palm pitch?  i tried the coke can test and my thumb points towards my ring finger.

I have always been good at adjusting using wrist positions, I would rather adjust wrist  position than move.  I wish i could get the easy revs that I had with the the original pitches with the relaxed fit the new pitches give.  Looking at the charts it seems the reverse of 1/4 for a 4.5" span with tight flexibility is on par, thus why I was thinking of more positive lateral like I had before.  BTW thumb is 2.5" long if that matters.

Thanks.  I will re-slug a ball I don't use and try less reverse and go from there.  I know I can't go any shorter on the span, so I hope going less reverse doesn't mean I would need to shorten it.
