[O.B.Left]

I'm just trying to understand how double cocking can cause a hook, given a mildly in to out path, and a ball that starts just right of target.

Im not Trackman savvy but those parameters would indicate a push shot more than a hook shot wouldnt they guys? Doesnt sound like much Divergence between Face and Path. Andy are you sure about your Path being "mildly in to out"?

Cocking your Right Wrist ........you dont need to do that. Its not necessary as a source of power and it breaks the Right Forearm Flying Wedge. Maybe if you only had your Right Arm to swing with but assuming two arms......its not worth the loss of structure as the Left Wrist can provide all the Velocity Power needed.

Imagine slapping something with a flimsy right wrist .......then with a frozen bent right wrist. The latter has more structure and more power although the velocity is the same.
