Let's try a simpler image: picture a table with a single central leg. Your left arm and the shaft move on the table (that's the left arm flying wedge) and the left wrist cocks and uncocks so that the shaft stay there. I take zero effort to maintain the left arm flying wedge on the table. The right forearm is the leg.

Now in the golf swing the tabletop is not horizontal but inclined, and in fact there is no real tabletop but the right forearm can be used so that the left flying wedge moves as if there were a tabletop, staying on plane with no tension.

That's a simplified image of how I picture the role of the flying wedges, please correct me if that's wrong or misleading.

The last sentence about correcting you - that is meant for somebody else, I quess and not me who's completely daft in this matter. I didn't understand your last image either.

I guess TGM and its users want me to see the two arms & hands holding the golf club as some sort of unit ( or 2) and that the backswing and downswing is supposed to be done in such a manner that this unit operates on plane in an effective geometrical manner (or something like that).

I just don't see this geometrical wedge in my head in a meaningfull way, but I know how the wrists are supposed to work and how the impact "position" ( the moment of truth ) should be and I am willing to leave it like that without seeing geometrical figures in my head without understanding their purpose. If I had understood it, it would make me happy - now it only makes me unhappy.

I quess this has a lot to do with angles? But I watched a video on youtube where a guy said - forget the angles - more important is PRESSURE (thru the ball I quess).

Therefore hopefully my body parts are doing it correctly (right wrist bent, left wrist flat and level) and that must be the important thing, not what the remaining body part - my brain inside my head - is understanding about what is going on geometrically spoken. I'm not sure I even understand what I'm saying (does anybody else?) Maybe I am more "positional" in my head than "alignment-oriented"? (Or just empty) A curse?
