Are we supposed to take the club back with the same amount of hinge action as we have in the through swing?

Hor.hinge: we swing back with a 90* turn of the left wrist. And swing through with 180* of roll.
Angled hinge: we swing back with a 45* turn of the left wrist. And swing through with 90* of roll.
Vert. hinge: we swing back with no turn?? And swing through with no roll.

Is this correct or am I missing something. Do I mix swivel and hinge? please clarify.

Rather than use degrees, Thom, let me answer your question in standard TGM concepts and terminology. If you use Hinge Action (10-18-C-1/2) as a substitute for Standard Wrist Action (10-18-A), then the Left Wrist will remain Vertical to the selected Basic Plane (Horizontal or Angled) in both directions. This Action will also maintain the Clubshaft In Line with the Left Arm and thereby maintain the Rhythm of the Stroke. When integrating this Action into your Total Motion, let the Turn Feel away from the Ball determine the Roll Feel through the Ball (7-10). Be sure to use a mirror and look, LOOK LOOK per 3-B.

Vertical Hinging is not the natural byproduct of either Hitting or Swinging and therefore will always be a deliberate mechanical manipulation. When using it as a substitute for Standard Wrist Action, a Reverse Turn (Counterclockwise Roll) Feel away from the Ball will be followed by a Reverse Roll (clockwise Turn) Feel through the Ball.
