Unless you are training yourself for some kind of move like the twistaway the hands shouldn't be doing ANYTHING except holding onto the club.
The left wrist cocks by the folding of the right arm (not anything you do with the left wrist), the left wrist uncocks by throwout action (unless you're hitting but even then you aren't doing anything with the hand or wrist you're thrusting the right arm). Lastly, as long as you are tension free in the swing the left arm will roll to the plane in the backswing and roll back to the plane in the downswing without help from you.
The key is to move your hands with your pivot and not move your hands with your hands.
Jim, I never said that the left wrist cocks... I said the left "hand" turns, the left "wrist" uncocks (I know that sounds funny) and the left "hand" rolls.
Can't it be that the left hand turn causes the right wrist to bend which in turn causes the right forearm to rotate consequently bending the right elbow (folding the right arm) causing the right hip to get out of the way and lowering the right shoulder? Of course it can....and does, only if you like. We have choices, if I've learned anything from TGM.
An educated pivot can only move (effectively) educated hands. Educated hands can only move (effectively) an educated pivot. But the real idea behind these concepts is being able to move the club. It takes both...one sequence or another...don't think it matters either way. However.....
The simple wording of turn, uncock and roll has a potential few have endeavored to explore. How much can the hands turn, how deep can the wrists uncock, how much roll do you need for the shot at hand...none, half, full?
If the hands are clamps then how do we deal with roll? Hold back if we don't want too much? I don't think so, sorry. Hands as clamps sure if you only want one thing. I want options to create, therefore, I look to see the potential of my hands and consequently the clubface.
