I find it interesting that after the 3rd edition the explanation of the 10-2-B grip type changed considerably...
1st edition
10-2-B V/V/A
Pull the Right Hand back from the top pressure point position of Grip A in order to conform to a
lowered left thumb position. This allows the Pressure Point to
drop to an Aft position. Do not
ROTATE the right hand to achieve this change. The pressure point is no longer on the plane of the wrist cock. The pressure point will be on the line of the Inclined Plane during Impact. The use of this Grip Type should be
discouraged until Grip Type A has been mastered.
Wow!!!....I wonder if this was prior to the "Flying Wedge Concept" or did it give birth to it?
Pull the right hand back?...from the base of the left thumb?
Lowered Left thumb position...to the aft side now in the same line as pressure points #2 & #3?
Dropped to an Aft position?...To where the Plane of the Sweetpot and the Clubshaft meet?
Discouraged?

...
Why I wonder?????????????????
