[O.B.Left]

Perhaps the confusion lies in the belief that there ideally is one singular "Plane" or one fixed Inclined Plane angle? While this may true intellectually and indeed practically for short shots, "The" Inclined Plane can and does Shift or change angles for longer shots. I cant think of golfer who hasnt shifted plane angles for full shots. Given the manner in which we define the plane anyways. (JIm Hardy's definition being a different kettle of fish, the plane of the shoulders vis a vis the left arm being one and the same etc).

From a DTL point of view, the angle formed where the Plane (picture it as a four sided rectangle along which the clubshaft or the more correctly a line between the #3 PP and the Sweetspot, travels at all times) meets the ground (the Base Line, Target LIne) can change. The club's lie angle defines the starting plane angle assuming you dont want to come into the ball toe up or down. The right forearm , or right Forearm Flying Wedge is said to be on this Plane Angle when the Right Elbow is on plane.

So "The" Inclined Plane or "The Plane" does not preclude changes in the plane angle, "shifts".

Also, Per 1-L-18 Machine Concepts. "Changing the Plane Angle has no effect on the Plane Line". Implicit in this is that Tracing the Plane Line accurately is far more critical than complying with a specific pattern of plane shifts. See Trevino, Furyk etc. There used be a really nice animation on this site that described this. If I can find it in my files Ill send it to you. It will make things clear as words sometimes fail us when describing geometry.

Yoda would, I believe, prefer the TSP in Startdown so that the Right Shoulder can get on the Inclined Plane and take the Power Package down that plane towards the ball initially. But this does not imply that he wants the clubshaft, right forearm, hands, #3 pressure point , sweetspot etc to stay on the TSP all the way to Impact. The fog will lift when you can imagine the Inclined Plane's angle changing as it shifts from a higher angle to a lower one. From say the TSP to the Elbow plane. Its the same plane of glass or plasic or whatever with different, shifting angles where it meets the ground. That is "The" Plane.

Further research has allowed me to see that I sometimes use the Hands Only Plane with no shift in total motion. Basically a wedge shot with the blade laid flat on its back, wide open and plane set super low. V.J Trollio invented this shot I believe. It takes almost all of the down out of the three dimensional impact as you scalp the ground on a severely flat Angle of Attack. The hands set below the elbow plane meaning the right forearm is no longer on plane. A super de duper lob shot. The open clubface avoids any lie angle, toe up issues given the difference between lie angle and Inclined Plane angle. A non shifting fixed plane in total motion.

As for using a fixed, non shifting Turned Shoulder Plane for full shots. Assuming the Right Forearm is on Plane at Impact, how do you reconcile the various lie angles through the bag? Would you have to bend each club so it points at the turned shoulder? I still dont see the right shoulder being on this plane at impact. Startdown only.

The Elbow Plane you could use , I think, without lie angle issues but its pretty flat aint it? There may be a specialty shot application for it but I dont see this on tv in total motion, I dont think. Even Hogan wasnt this flat.

Maybe I need more incubation time on this , sorry.
