This is a question for Yoda: Can you use angled or any hinging for that matter on the backswing? I thought hinging action was determined from impact to follow through.
The Left Wrist Action (Component #18 ) is Clubhead Control and is in operation from Start Up to Impact. It has two Planes of Motion: Rotational (Turning and Rolling) and Perpendicular (Cocking and Uncocking). The Standard Action (10-18-A) is a Swivel Action -- Hand Motion independent of Arm Motion. A Left Wrist that is Turned and Cocked on the Backstroke must subsequently be Uncocked and Rolled on the Downstroke.
Hinge Action (Component #10) is Clubface Control and is in operation from Impact to the end of the Follow-Through (the Both Arms Straight position). Hinge Action has only one Plane of Motion: the Vertical 'center position' of Rotational Motion. This Vertical Condition of the Rotational Motion is executed by the Flat Left Wrist remaining Vertical (perpendicular) to one of the three Basic Planes (Horizontal, Angled or Vertical).
At any time, the player may substitute Hinge Action for Left Wrist Action during the entire Stroke (7-10). Here, instead of true Hand Rotation -- independent Turning and Rolling -- the Left Wrist remains Vertical to one of the three Planes. Though the Left Wrist may appear to Turn on the Backstroke and Roll on the Downstroke (especially with Horizontal and Vertical Hinging), it is simply remaining vertical to the selected Plane of the Clubface Motion through Impact. Hence, there is no true Rotation of the Wrist. Nevertheless, from Top to Finish, the Stroke may take on the Feel of one long, slow 'Swivel' (2-G).
However...
When utilizing the Hinge Action alternative during the entire Stroke, the player should be aware that at some point, the Shoulder and Arm Motions gradually bring the selected Hinge Action Variation into an On Plane condition at the Top. This 'palms parallel to the Plane' alignment is identical to the Standard Wrist Action with its independent Turn and Roll.
Thus, other than the true Single Wrist Action of 10-18-C-#3 (wherein the Left Wrist does remain truly Vertical throughout the Stroke), the Wrist in the Backstroke gradually Turns (but is not Turned!) and in the Downstroke gradually Rolls (but is not Rolled!). Any forced attempt to maintain the Left Wrist Vertical is unnatural and will produce both an Off Plane Clubshaft and a most un-Golf-like Stroke, conditions intolerable to the the thinking player.
