Concerning the start-up picture (top row - right).

Doesn't the toe of the club pointing up indicate that he is using horizontal hinging ? If that is so, then the left foreman must have swiveled (clockwise). Also, with only a small amount of extensor action, the left wrist would become flat instead of bent (4-A-2).

It also looks like that his left wrist is flat at the end position.

Thanks for the pictures and comments.

Here's how I see it....

Both Wrists were Vertical to the ground at Impact Fix. When BH assumed Adjusted Address, His Wrists Turned Slightly (geometry only, no hand movement but the shaft is not vertical to the ground so now his hands are slightly turned to the ground). So, Startup begins with a Slightly Turned Left Wrist, but no Swiveling is done during startup. Single Action during Startup or Backswing refers to wrist activity or motion occurring after address. In other words, they may have been already Turned a litle to Plane at adjusted address but since no further motion occurred, Single Action Startup and Backswing.

I don't thing that Extensor Action necessarily requires that the Left Wrist must Flatten when applied, only that it will if you allow it. Consider applying pressure through the #3 pressure point or that during a Startup Swivel the Right Wrist stays Flat. Additionally with EA,the Higher your Raise Your Hands at the Top or End of your Swing (Steeper plane) the Less Bend angle in Right Elbow. So, the Top of Your Swing Elbow Bend Angle is the same that's needed needed for the Right Forearm to be On-Plane at Release, provided that your hands follow a path directly to/at the Ball. (the Turning Shoulder Planes have their basis in this concept) Right Elbow Bend does not change. Only EA takeaway and Backswing can provide this Action/geometry because the Club is lifted from the Right Shoulder joint using triceps muscle for any swing. On the other hand, Hogans Elbow becomes increasingly bent during the Backswing and then unbent during the Downswing.
One advantage of of Hands controlled Pivot is using a Single Plane during the Downstroke, not needing to re-route the hands (delivery paths) and second, is not having to change the bend in the right arm to become on-plane at Release.


The Left Wrist at the Top looks Double Bent (Cocked and Bent). to me.
