...I am still vexed about exactly what Homer is saying in 10-10-C is identical to paddle-Wheel but is a superior procedure. Is he talking about Left Wrist control is superior to trying to control the clubface with right arm straightening?

Secondly, would you ever recommend having a shut clubface at the top with vertical hinging to Hit?

The issue actually is Clubface Paddlewheel Action (2-G) and whether it is best executed as Left Wrist Paddlewheel Motion or Right Wrist Paddlewheel Motion. In either case, both the Left and Right Wrists are held Vertical to one of the three Basic Planes. In the case of Angled Hinging, that Plane is the Angled Plane of the Stroke.

But the Right Wrist Bend -- and hence the Clubface alignment -- is easily disturbed by variations in Right Shoulder Location and its effect on the Right Elbow's Impact Bend (2-H). The Left Wrist is subject to neither of these interferences and is thus best suited to the task of Clubface control.

Regarding the 'Shut' Face with Vertical Hinging, the Left Wristcock is always a Perpendicular Motion (4-B-2), even when executed on the Inclined Plane. And this is true no matter which of the three Hinge Actions are employed. Then, whether the Clubface is Square, Open or Shut (using the conventional terms) at The Top is a function of its alignment during the Grip Routine and any adjustments to the normal Impact alignments of 2-J-1. That is, Grip Type per 10-2-0-1 or Clubface Manipulation (Grip Rotation) per 7-2 or both. And, also, the Ball Location per 7-11, that is, the Clubface aligned more and more Closed (within the Flat, Level and Vertical Left Hand Grip) as the Ball is moved toward the Right Foot.
