There is a MAJOR difference between pushing PP3 against the shaft with the intent of straightening the right wrist to move the clubhead that also bends the left wrist and eliminates rhythm (throwaway- unprincipled), with, PP3 feeling the Lag through the Impact zone as the right arm straightens with a residue (no intent) of flattening after impact.

I would agree that the right wrist unbends as the left wrist uncocks-but it unbends only to the point where the left wrist is flat-and no more and therefore stays bent.

:-? Not sure what you mean, Neil.

My right wrist bends with the left wristcock on the backswing.It is slightly less bent at impact after uncocking the left wrist.

So the left wrist is cupped at the top and returns to flat at impact? Does the right elbow control the cocking and uncocking of the left wrist? I like the image of the frozen right wrist...maybe that only applies to swinging.

from Adjusted or Standard address- the classic cupped LW and Flat RW set-up, on take-away the LW flattens and the RW bends. This can be done with Extension Action or by actively folding the RW back and Turning flat the LW. This is a Swinger's procedure.
The LW can cock either by the folding right elbow- more a Hitter's procedure or by Momentum Transfer, a throw that snaps the LW cocked.

Hitter's from Impact Fix already have the Flying Wedges set- flat LW and a bent RW. They can keep it 'frozen'- that means each half of the Flying Wedge is frozen in its operational plane. Frozen is not stiff or cement like.

The trick is to examine Impact Fix and see how bent the Right Wrist needs to be for that club and ball position. It is not a "one fold fits all" clubs or strokes.

As for a cupped LW at the top- some play that way- but compensate and add another movement on the Down Stroke. Best to just set up perfectly and let Extensor Action do its magic.

Should I even be in this forum ? ,Swinger that I am !:golf:
