Could you say the 3 imperatives can be controlled by the REAR hand, wrist, forearm?
Example, Flat lead wrist, keep the rear bent, keeping the rear bent keeps the lead flat.
Straight plane line, trace the plane line with #3 pp. up and back.
lag pp. #3 on the rear hand.
In TGM, the right hand bend controls the flat left wrist. The left doesn't flatten as a self contained action but as a result of the right hand bending level. PP3 tracing of the plane line is the Magic of the RIGHT forearm as Yoda explains. PP3 is pushing right to left into impact creating a lag BUT... pivot, left arm leads ahead of the club. Lag is a trailing of the club, not just a right side hand push.
The right hand controls the c0cking of the left wrist as the right elbow folds on takeaway, another right side action.
I like YES. If you want the right wrist to arch the left wrist- go away, the point was that the right wrist moves the left wrist straight. I'll stick with the way Homer and Yoda likes the left wrist- FLAT. You cannot have two wrists bending in opposite directions. You can incorrectly c0ck but wrists into a cup, but why?
