[Yoda]

Yoda,
Bobby Shave (channelling Mehlhorn) doesn't stress extensor action much. As such, he recommends a very soft left arm position at the top without wrist cock. Maybe he just relies on downswing loading.

Extract the principles of the Mehlhorn text -- Body Rotation (Zone 1 / the Pivot and Balance); Free Arm Swing (Zone 2 / Power and Clubhead Force); and the Vertical Left Wrist and 'Direct Line' (Zone 3 / Closing Only Clubface and Plane). Also, embrace Wild Bill's thoughts on ball control and course management.

As always, avoid extremes and 'ungolf-like' motions.

Finally, get the Mehlhorn DVDs and emulate what you see. Also, note his exceptional emphasis on the Right Forearm and its participation in the Stroke. Unfortunately, that emphasis was captured only by 'The Man' himself. It is absent in the transcriptions of his taped conversations that form the text of the book.
