[O.B.Left]

#3 Angle , the Angle formed by the left arm and clubshaft, "roll power", can be zeroed only by gripping the club along the life line in the left palm. Something we do to deaden the send associated with any left forearm roll when putting or for some when chipping. With a "normal" left hand grip going to fully uncocked approaches zero angle but doesnt ever reach it.

Startdown is on the TSP, Impact is on the Elbow Plane. The closer these two plane Angles are to each other the less "The Plane" is required to Shift Angle wise. Thats a good thing. The Elbow Plane is essentially the Shaft Plane when the Right Forearm lies on it. The TSP Angle varies with the type of Shoulder Turn employed in Backstroke, length of club etc. Getting the Power Package on the TSP you have chosen at Top precludes the need to drop the Hands from a higher plane onto the TSP prior to initiating an On Plane Downstroke. This is a good thing, as all plane shifts are hazardous, (though some are inevitable from Top to Impact for full power strokes, not putting, chipping etc)
