Here's a couple of quotes from the book :

CHAPTER 2 STATEMENT OF PRINCIPLE continued
PAGE 24
DIRECTIONAL VECTORS
The force of the Impact will hold the ball against the face of the orbiting Clubhead and so carry it along the same circular path. This places the ball under the laws of Centrifugal Force. Which requires that the ball leave its circular path at right angles to the radius of that path at the point at which it leaves that path. But the hook-face alignment of the Clubhead – designed to give it the proper relation to the Plane Line – diverts the ball from its true tangential path. This geometric alignment assures full production of straightaway velocity by assuring no glancing action other than for producing backspin. Study 2-J and 2-F.

The second last sentence is the one that causes me some trouble. It will play a big part in whats coming as it relates to what Homer refers to as the Straight Away Position. I dont get it frankly. Would there not be divergence albeit lessened by steeper plane angles . Maybe some body can explain it to me ...

The proper horizontal motion of the Clubface controls its alignment during Impact. Only the putter is so constructed as to permit visual alignment. All other Clubs are angled – or hook-faced – in relation to the Clubshaft.

I know Ive read about hook face in other contexts ( a more "dynamic " version if you will ) somewhere in the darn book .... cant find it right now.. Has anyone got em handy?
