From 2-G, HINGE MOTION (page 28, first paragraph): "....an alternate reference point is needed. The Left Wrist position is a dependable standard...."

From BALL BEHAVIOR, 7-10 (page 103, last paragraph): "...the real control comes with moving or holding the Left Wrist in the positions called for by the respective Hinge arrangements."

it is very important for Swingers to learn how to perform all the Hinge Actions since they only use HH without control. Hitters have much better clubface control. Even if you don't use them in full shots- Swingers will gain great insight to ball control for their short game. As Homer said- "Learning only one Action isn't so helpful because you won't know their differences."

The added value of the Flat Left Wrist controling the Clubface is Rhythm Control, 6-B-3-0.
