Use the Turned (Right) Shoulder Plane and eliminate any Start Up Swivel in the Backstroke.
From there, delay the Release by keeping the Left Hand Palm Down (to the Plane) -- and the Right Hand Palm up -- through the Release Point and then Swivel into Impact.
Am I right, Daryl?
Quite Right. And 10-18-C #1 has fewer moving parts than a Start Up Swivel. Besides, the Downstroke Pre-Hinge Swivel on a Turned Shoulder Plane has more continuity while tracing a Straight Plane line. Especially compared to that of returning to an Elbow Plane from a Double Shift. These mechanics contribute to the Longitudinal Pull feeling that I've been missing rather than the 'yank Ye-O club around' feeling I've become accustomed to.
