What you have stated makes a lot of sense - the amount of roll a golfer gets (during the horizontal hinging action) depends on the angle between the clubshaft and left arm (as seen from a DTL view).

Although HK states that the left hand is responsible for controlling the clubface during the hinging action, doesn't the degree of straightening/pronation of the right hand during the followthrough have a major effect on the hinging action.

Consider capture images from the Anthony Kim video.



I get the impression that his right hand is straightening and pronating during the followthrough. Doesn't that right hand action induce horizontal hinging by promoting a roll action during the followthrough period? Isn't that right hand action what Nick Bradley describes as a puck release - see the next photo?



Jeff.

Left hand is responsible for clubface. It is possible to over-ride that condition by this puck move of Bradley. You lose flat, level , and vertical left wrist. You shorten the radius to the left wrist. You lose the rhythym component. The club is no longer in the plane of the left wrist cock.

DTL is the right view to examine #3. Face on would be better to see if his right wrist unbends as you describe. I would think that if Kim were doing so, we would see the shaft bending up around the wrist and up some plane rather than appearing to point to the plane line, still in rhythym with the left arm.
