[Yoda]

After uncocking the left wrist, is the roll of the left arm an action of it's own? or a result of the pivot? To clarify the question, if I stand with my palm to the plane line I can either rotate my left arm on it's own, shoulders parallel to the target line, or I can turn my shoulders to rotate.

The rotation of the Body and the natural swinging of the Arms imparts the Hinge Motion to the Hands and Clubface. The Flat Left Wrist then individualizes this Motion into one of the three distinct Hinge Actions (Horizontal, Vertical or Angled) and the Clubface respectively Closes only, Lays Back only, or simultaneously Closes and Lays Back. If there is no Body Rotation, then only the Arms are reponsible for the Hinge Motion.

If there is Wrist Action independent of Arm Motion -- the Flat Left Wrist does not stay vertical to one of the three Basic Planes -- then there is a Swivel Action. Swingers find the Swivel useful in Start Up, during Release and as the bridge from the Follow-Through to the Finish. Hitters normally use only the Finish Swivel. For both Swingers and Hitters, Impact executed as a Swivel Action -- and not a Hinge Action -- is improper Execution and results in fleeting Impact alignments.
