Basically I've been doing the underhand spiral drill with a football but I'm having trouble duplicating that feeling on a bowling ball.
When I throw an underhand spiral with a football, it feels like the ball rolls off my fingers, but when I try to duplicate that, it instead feels like my fingers are turning the ball. If I were to describe it better, it would be like the feeling when you first try to hook the ball, that over rotation of the wrist kind of feeling.
This feeling using a bowling ball really ruins my consistency. If I can have that of the ball rolling off my fingers feeling like the football drill, it would really help my game.
I theorize it could be something with my ball fit because of the way the football rests in my hand. My fit is as follows.
Span: 4 1/4 M 4 1/4 R
Finger pitch: 3/8 lateral L 3/8 lateral R
0 Foward/Reverse Middle finger 1/4 forward Ring finger. Both use powerlifts.
Thumb pitch: 0 lateral
1/4 forward
If anyone has any advice regarding my fit or how I could transfer this underhand spiral feeling to how I throw a bowling ball. I would appreciate it.
