That makes sense MJ .....thanks. Effective though Rolling is, its not a little bat or flipper, lever deal per say. Its more about optimal contact. Keeping the point of contact between ball and face intact "as if welded together", no slips or wobbles except for that due to club face loft.
Would you agree? If so what does that do to Hogan's "little bat" or A.J.s "da bat" ? It'd still work but not for the reasons described I guess. Interesting.
Face roll just changes the attitude of the face, I don't see how it could keep contact intact or weld the ball and face.
Ah ha! Now I understand Yoda's reference to "da bat"!
