Got another one which we've talked about briefly.
With reverse, although it allows a perfect release, it needs a perfect fitted thumb. So, whenever there's any shrinking or expanding of my thumb for any reason, I may not feel it immediately, but all of a sudden the ball won't feel right for 2 frames before I think of adding or removing yet another piece of tape.
With less reverse, 0x0 in my case, my release remains good while I feel the change (the need for more or less thumb hole tape) BEFORE it affects my release. That is A VERY GOOD THING!
