2 Sides of a Coin?

10-2-D STRONG DOUBLE ACTION T/V/A Now the Right Wrist is Vertical and the Left Wrist is Turned to the top of the Clubshaft so that the Left Wristcocking motion will be on the same line as the Right Wrist Bend. The #3 Pressure Point and the left thumb are also on the same line as the Right Wrist Bend. Double Action – same as 10-2-C.
I'm a little concerned about that. 10-2-D doesn't Roll through impact. It seems to me, that the Clubhead/Clubface is uncocking going through Impact. If that's true, then they aren't traveling at the same RPM. The same RPM occurs with Roll when the Swingle doesn't pass the handle.

You left this part out of the quote . . .

This Grip Type features maximum Wristcocking action and strong support for both Acceleration and Impact loads. The palm of the Right Hand moves toward Impact exactly like a paddle-wheel rotating On-Plane – no separate Rolling Motion until after Impact. See 10-10-C.

10-2-D is just one big Karate Chop . . . throw the FACE at the ball . . . Rolling is for biscuits.

Here's what we been feudin' over in the Swinger's Sections (OK who's going to be the first nerd to leap on that!) . . .

I keep telling you this stuff is in the book . . . I don't make it up . . .

10-2-G TRIPLE OF QUADRUPLE When the above Grip Types are MODIFIED by Rotating the Hands so that either or both Wirsts cannot Cock On Plane without also Bending, Feel loses its geometric basis. Also the natural Wrist motions conflict. A bit of Left Wrist Turn properly becomes exactly the same amount of Double Wristcock to keep the Clubshaft On Plane and to maintain Impact Wrist Position. Except with a “True” Swing (6-B-3-0) where Centrifugal Force will produce the “geometric” Flat Left Wrist when there is actually a “visual” Bent Left Wrist. That is, the Clubshaft and the Left Arm are in a straight line per 6-B-3-0 and 2-K regardless of the Left Wrist Position. These procedures may be either “Weak” or “Strong” but either or both Wrist are Double Cocked per 10-18-B.
