[12 piece bucket]

When exactly is # 4 out of ammo? Another plea for a centered head. Does a sway interfere with a players ability to swing the left arm across the chest?

Jethro . . . See the pic 6-B-4-0 #2 . . . . it's basically spent when it's in line with the shoulder joint . . . 90 degrees . . . . so it's loaded then as the arm swings down it is releasing and released at 90.

I'd say that physical limitations and plane angle or just plain bad concepts (such as "I have to have width in my backswing") limit the left arm going across the chest. Not sure swaying would on the backstroke . . . HOWEVER I think HOLDING ON TO #4 can certainly result in Bobs and or Sways or uncocked right wrists because of a radius disruption or plane shift resulting from the hands being pulled under or over plane . . . you gotta figure out how to get the clubhead on the ball via some sort of compensation . . .
