To quote "Clubface loft (2-C-1) and Hinge Action (2-D) determine altitude and backspin and are the basic elements of Ball Control."
Can someone explain to me why hinge action has any effect on the above parameters is loft is given. Isn't it redundant? Shouldn't it just be Clubface Loft determine.....
or
Is he saying that the hinge action creates a loft and it's just poorly written?
HK is saying that much of the Spin on a Ball is caused by the Line of Compression although some spin is caused by the ball rolling on the face of the inclined striker. Hinge Action controls the Line of Compression, therefore Hinge Action also is a factor in determining altitude and Spin; Ball Control.
