Personally:

-I think you can be Hands To Pivot and Shift Planes.

-I think Plane Shifts influence the Hand Path, obviously. 10-23-A is Single Shift , 10-23- B,C and D are Double Shift.

-But Hand Path does not determine the Release Point. You'll notice that 10-24 illustrates all five Release (s) using the 10-23-C Hand Path (Double Shift).

-I believe Plane Shifting is hazardous , for sure, but so is crossing the street. You need to rank your hazards. Hogan was a Double Shifter and hit out of his own divots. Plane Shifting should be ranked way below Plane Line compliance in a hierarchy of Geometrical needs.
