6bee1dee's point about the bent right wrist is good advice. I know that Yoda has recommended hitting 50 short pitch shots per range session with a wedge and with the right arm/hand only, concentrating on getting to the "straight right arm" position while maintaining that bent right wrist. I can see the value in that little exercise after doing it for the last couple of days. Seems like you REALLY need to get used to that feeling (and it does take some getting used to, at least it did for me) or the left wrist will always be a little unpredictable.
Stay with that Acquired Motion (12-5-2) Right Arm (only) Paddlewheel Action,Hank. Bend that Right Elbow in Start Up (7-3), and then Straighten it (7-1) ina Non-Auto Sweep Release (10-24-B) on the Downstroke. Keep the Left Wrist Flatand the Right Wrist Bent (4-D-1) throughout the Stroke.
Soon, when you put your Left Hand on the Club (10-2-B) with its terrific LeftArm Checkrein Action (6-B-1-0) of the Right Arm, you'll feel like you'recheating! The Clubhead (2-N-0) will be under total control.
And then, to be able to manipulate the Clubface with one of the threeFlat and Vertical Left Wrist Hinge Actions (2-G and 7-10) is just too much!!
