His stance on everything was very narrow, his niblick or nine iron shots was not very far apart. He said it didn't lock up his hips, which is a great sorce of power, i developed it in my game, added yards on every club and dropped to a 3 handicap from a 6. Also helps on uneven lies, it's easier to align your shoulders to the slope.
He didn't play a hard swing with long distance. He was all precision but gave up a lot of distance to big hitters. Nicklaus and Woods Swing much harder
