I'm currently drilling 3/8 reverse pitch on my thumbhole, but I've been struggling to get a clean release.
To get the ball off my hand cleanly I've had to bevel the front of the thumbhole quite a bit. But to get a good snug fit I've also been using two pieces of thumbhole tape in the front, along with four short pieces of tape in the lower front.
Could I achieve the same effect by just increasing the reverse pitch in my thumbhole?
What's the greatest amount of reverse pitch you've seen?
