Right Forearm Position at the Top differs for the Angle and Arc of Approach procedure. So their Elbow location and action differs also. For Hitting (10-19-A), the Right Forearm should be precisely in-line with – and directly opposed to – the motion of the On Plane Loading Action (7-22) of the entire Primary Lever Assembly (6-A) not just the Clubshaft, and this alignment is maintained through Impact (2-J-3, 4-D). For Swinging (10-19-C) the Right Forearm should be precisely in-line with – and directly opposed to – the motion of the On Plane Loading of the Secondary Lever Assembly (the Clubshaft) and this alignment maintained through Impact. In compliance with both 6-B-3-0-1 and 10-11-0-3. With this “in-line” relationship of Loading and Right Forearm, it is absolutely MANDATORY that, Hitting or Swinging, it is the Right Forearm – not just the Right Hand and/or Clubshaft – that must be thrown, or driven, into Impact per 7-2-3
Got to be careful with Homers "Swinging vs Hitting". In 6-H-0 for instance he's talking True Swinging vs Drive Loading not Swinging vs Hitting general per say. In the above quote he's talking Drag vs Drive Loading , Arc of Approach vs Angle of Approach ( as an aside you can Hit and use the Arc) and assuming a certain grip type, wedges 90 degrees etc. So to answer your question , 4B Drag then Drive is a different animal, neither 12-1 nor 12-2.
Here's one for you. You say Angle of Approach is cross line, closed plane line (correctly) and then show photos of Arnie hitting a driver. Assuming Arnie positioned his ball at low point with that driver........If the Angle of Approach is a straight line from Impact to Low point .........wouldnt it, the angle of approach be straight line , square, inline with the target line?
And what are the implications to the quote above given a Hitter using the Angle of Approach who positions his ball at low point? For a Hitter using the Arc of Approach? How might these Hitters differ in terms of elbow position? Club shaft Plane Angle? Club head plane angle? Pivot participation?
There are 4B Hitters , there are 12-1 rs , there are Angle of Approachers , Hitters using the Arc of Approach , there are options, lots of options .......lots...
