Plgolfer, do you mean your Left Thumb extends as you cock the Left Wrist?

No. What I mean is: At address if I cock my left wrist by lifting the shaft vertically with the mid finger of my right hand I need to relax the grip of my right hand to maintain a level right wrist.The life line cup in my right hand will then dissociate/slide
above the base of my left hand.

Yoda shows this cocking action of the left wrist in the dvd series with the fingers of his right hand lifting the shaft. But then he was not gripping the club in the usual way. Thanks for your clarifications. I wonder if I am missing some major alignement here.
