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.

Thanks for your reply.

My confusion was foremost with the vertical hinging. It doesn't feel as if you can be very powerful when you're making the reverse turn in the backswing. But I guess that's why the vertical hinging is used primarily in the short game.

But you can always choose to swing back with standard wrist action and swing down and through the ball with any of the hingeactions, can't you?

As a neohitter I understand why it's suggested in 12-1-0 to use 10-18-C-2 for hitting.
Swingers should use std. wrist action (12-2-0). Are the difference between 10-18-A and 10-18-C-1 the start-up-swivel vs. gradual turning with the hinge action? It seems that they are both ending up in the same position on top.
