You become a product of your environment. I'm going through a bit of the same thing. With most of the sport shots (and my rev rate/speed) I'm better off more up the back of the ball and more direct on the lane. When I get to a shot that is best attacked by looping the ball, I'm no longer very good at it. I used to hook the ball a lot, now I really have to work at going left to right and coming around the ball enough.
I think Dave81644 may have said it better.
