Couple of point :
I have 2 6th editions.
Oldest copy has the 12-2 error in 23 says C then straight line- as mentioned
newest copy has a sticker over 23 and 24 and the change to 23 is A then top arc and straight line- transposition of the error. I got it new that way- anyone else see this??
I wish the explanation of swinging/hitting said this is how to move the "hands" not "clubshaft/clubhead".
It is a feel to me that (beyond the application of force) it is the PIVOT that creates the "out" in swinging and the "around" in hitting.
