Brick, did you track change any? With my current game, I can throw forward roll with a good track, once I start to change my hand to change my roll, it cocks my thumb really funny in the ball and I cant get the ball off my hand causing a spin. It pushes my thumb out away from the plam really bad and I am already using 3/16 away from palm lateral. This is one big reason why I think I need a change also.
