While I've only been exposed to Mac's ideas at a very minute level, his concept of '45 degrees' is quite solid and something I often find myself coming back to in my own swing experimentation. The simple answer to the grip question IMO is that the left hand grip at 45 degrees is both anatomically, and geometrically in balance - given a right hand that is basically verticle to the plane.

As for Clearwater, yeah, I remember watching him at the 87 Open and I thought he had one of the best swings on tour, great to see him and Purtzer on the range, and the course - I think Keith shot a 64 in the opening round (my memory may be failing me there). I do see what you mean about him coming out of his angles though.
