My, look at that Ball Rolling up the Face of the Clubhead in Frame 2. Does anyone believe that the Ball "Rolling up the Face" of an inclined striker accounts for all of the Spin creating Force on a Golf Ball? No, I didn't think so. Only Jorgensen thought so, and he's a Physicist.

2-A .....Roll of the ball on the face of an inclined striker does not account for all the action produced by such an impact, especially in imparting spin to the ball.
