........ I personally have the wedges at about 90 degrees , (never measured em) but when writing I didnt want to exclude the stronger Left Hand Grip dudes with their (approaching) Single Wrist Action. Some have Turned their Left Hand all the way to Plane in their grip , at Fix and IMO do not have their wedges at 90 degrees therefor. ..........

This is such a great post I can't resist commenting but I didn't want to copy the entire post because there is a limit to storage space.

Just so we agree, because the Terms are really confusing. "Turn and Roll" describe the Primary Lever, using a Vertical Left Wrist, moving away from (backstroke) or toward (forward) Low-Point. So Turning is the Primary Lever moving "Away" and the Clubface "Opens" and Rolling is moving toward Low-Point and the Clubface "Closes". For the life of me, I have no idea why HK would use these terms. Swiveling occurs when the Clubface (Left Wrist) changes from Vertical to On-Plane and back to Vertical again.

90 Degree Wedges. If your Left Wrist is Vertical at Low-Point and your Right Forearm Wedge is On-Plane, then the Wedges are at 90 degrees.

Here's where we differ; I think. My opinion is that the Wedges should remain at 90 degrees regardless of Ball Location (its ok if they're not if you prefer it that way). If you play the ball back 6 inches, then, at Impact, the Primary Lever will be Closed but Rolling. It will also be Swiveled and will be Swiveling toward Vertical which it will be when it arrives at Low Point. For the Clubface to be square to the Angle of Approach at Impact, you will need to rotate the grip of the club in your Hands. So at Impact, the Hands will be moving exactly as they would (but on a steeper plane) if the Impact were going to be at Low-Point.

I need to make a "Fine Point". It's pretty advanced but I think everyone can handle it and not lose sleep tonight. "Swiveling" and "Turn and Roll" are not opposites nor are they related. "Turn and Roll" is one concept, separate. "Swiveling and "Hinging" are related. They are Two different ways that the Clubface moves through the impact interval. Hitters Only Hinge. Swingers use a Hinge and Swivel but its not a Hand Swivel. Swingers use a "Release Swivel" whereby as the Hands move down Plane during the Pulley, the Clubface moves from On Plane to Vertical at Low Point. This Swivel is compatible with Hinging whereas Hand Swivels are not.
