Do you have the book? What did he say about hitting behind it?
I have hit some shots like that intentionally when the ball is sitting crappy. You can hit some soft shots that way. Interested to hear what he has to say. He was the flavor of the month not long ago.
I saw him playing at the Masters back in the 90's . . . he was still sportin' a mullet . . . lookin suuuhwheat.
