[Yoda]

Yoda, can you please elaborate on what you mean by bringing the Left and Right palms On Plane at the Top?

The Left Arm Flying Wedge with its Flat Left Wrist and On Plane Clubshaft lie in the same Plane...the Vertical Plane of the Left Wristcock Motion (6-B-3-0-1). The Right Forearm Flying Wedge with its Bent Right Wrist and On Plane Forearm is positioned at right angles to this Left Wristcock Plane.

During the Backstroke, the Left Arm Wedge Turns (Single Wrist Action) or is Turned (Standard Wrist Action) to enable the Vertical Wristcock Motion to occur on the Inclined Plane of the Stroke. This is the 'palms parallel to the Plane' alignment necessary for the Top (8-6) and Finish (8-12) movements involving Wristcock.
