My release gives me about 45-55 degrees of rotation. That's about the most I can get without forcing it right now. I'm pretty sure just the way I position my fingers is enough to change it. In here both fingers are spread far, I don't find I get anymore rotation with the pinky in, and I just move both fingers in as I want to reduce rotation. Hopefully beyond that it's just a matter of letting the ball roll off my hand which is what I try to do. I've been thinking of trying to come out with an open hand ala Pete Weber
just to be sure I won't turn early and that I'm not forcing the rotation.
As for my grip, the rubbing is definitely the ball, I only have to put my hand in the ball and try to pull it out(which is a struggle).
I will definitely continue to work on my game. I made a slight change and now, for the most part, it seems to be coming together. Still wondering if I should bend the knee on my power step more, speaking of which, it doesn't seem like much of a power step lol. Just curious, is anyone surprised to hear that I was squeezing the ball here?
