With due respect to the eloquence -- and accurate and important information -- of all parties in the quotes above:

Swingers with their Drag Loading Pattern (12-2-0) should totally ignore the Angle of Approach Procedure.

Hitters should explore it, but only after they've mastered the Drive Loading Pattern (12-1-0).

The two cited Stroke Patterns are structured so that moving from one to the other (Hitting versus Swinging) can be accomplished with a minimum of disruption to the player's Basic Pattern. Therefore, both Patterns use the Square-Square Plane Line / Stance Line Combination (10-5-A).

The Angle of Approach procedure described in the quote above uses that Square Plane Line (the Geometric Plane Line) to determine the new Angle of Approach Delivery Line. From that point, the original Plane Line becomes irrelevant. Hence, it is a procedure foreign to both the Basic Stroke Patterns.

Bottom Line: the Angle of Approach Procedure is For Hitters Only. And then only when you know you're ready for the ultimate sophistication in Golf. Until then . . .

Stay away.

I see, I am way over my head in these matters. But for those involved, I hope this sets the record straight...
