The Lee Buck question is pretty simple to answer. It's the same answer for David Duval and Lee Trevino.

They played the game "shut-faced" to borrow a term from SftPS (I know it's not a very popular book in TGM circles, but I really feel think it's a solid manual to follow.). What that means is they take a strong grip, a flat left wrist and much less supination and pronation than a typical technique. Essentially, they are blocking off hooks and hit powerfades all day long.

This is (imho) the most accurate way to swing.

Also, I don't believe hooks have much to do with having your wrist flat or bowed or arched at the top, regardless of your grip. In essence, regardless of your grip, your hands will have opened to the same degree. this does not mean they open the same amount however, just that the left hand/wrist will turn to [EDIT(typo) address] the swing plane regardless of grip (ie a weak grip will open more than a strong grip). On the way down, your natural inclination is to rotate the hands/clubface the FULL 90* regardless of grip. The result? Hooks with a strong grip.

Therefore the assumption is that a flat left wrist + strong grip = closed clubface. that's not really true because the bending of the wrists can in no way open or close the clubface (we can all agree there). This leaves us in a strange place: if the clubface pointing skyward at the top isn't really closed, why does the ball hook? that answer is a bit of conjecture, but mine is this: the unbending of the left wrist/bending of the right makes it harder for the right to work back "on top" of the left (and vise versa), which is the same motion as closing the clubface. (I need a better term than working back on top...do you guys know what I'm trying to say?)
