[Yoda]

Yoda - this issue made me think of another question, which I have now added.

If a golfer has flexible wrists, and he can bend his right wrist back to 90 degrees at the end-backswing position so that he can get his right forearm angled closer to 90 degrees relative to the clubshaft at the end-backswing position, is that a disadvantage?

. . . I was wondering whether it is disadvantageous to allow the right wrist to bend back fully by the end of the backswing - thereby altering the angular relationship between the right forearm and the left arm flying wedge?

The Left Wrist is the Master Wrist, and ideally, dictates any movement (Horizontal, Perpendicular or Rotational) of the Right. The Bent Right Wrist at Impact, then, is the complement of the Flat Left Wrist, and this relationship is established no later than the Top.

Any undue Bend (Horizontal Motion) in the Right Wrist will produce a corresponding Arch in the Left. While a "small amount is advisable and useful . . . as amplification of the Clubhead Lag" (4-A-3), any exaggeration will disrupt the precision alignments of the Flying Wedges and, hence, the entire Power Package Assembly.
