For Ideal Compression (2-C-1), on all Planes (Inclined, Horizontal or Vertical) the Flat Left Wrist remains Vertical (to the ground / horizontal plane) through Impact. This assues a 'Closing Only' Motion of the Clubface, i.e., no Layback (and hence, no loss of Compression).

Assuming a golfer operating on the Horizontal Plane -- a very unlikely situation -- the Feel will be No Roll. On the Inclined Plane -- almost always the case -- the Feel will be Roll. In both instances, there will be a Full Roll of the Clubface (Clubhead toe along the Target Line in the Follow-Through / Section 11). Not the Half-Roll of Angled Hinging or the No Roll of Vertical Hinging.

If you do not understand what I have written -- almost certainly the case -- you do not understand Hinge Action. Then, there are only two courses of action:

1. Quit, and forever rail against the 'complexity' of precision Mechanics while embracing the inadequacy of stand-alone Feel, or . . .

2. Study, and, ultimately, command the Action and own your Golf Stroke.

The choice is yours.

Yoda - would you agree that if you rephrase "flat left wrist" remains verticle to the ground in your bold above with "left arm flying wedge" (plane of the left wristcock) it is still a correct statement?

The reason I ask is that I've found for my grip, a truly verticle left wrist, makes it nearly impossible for me to create proper horizontal hinge motion of the clubface without a lot of compensation. Perhaps simply the way my particular anatomy functions. Much easeir to create a horizontal hinge, toe down the line at follow through if I take my natural left hand grip, the way it hangs at my side. Suffice to say, I am not a fan of the often heard phrase "back of the left hand faces the target" for the left hand grip.
