"I can count on one hand the number of people I've seen who can make it work."

How many tour players have you seen? That's a lot of fingers for one hand.

Quite a few. Notwithstanding Tiger, (since nobody knows what he's doing) are you telling me you see Retief, Ernie, Toms, Vijay, etc. all madly spinning their hips?

There's a guy by the name of Mark Wilson playing the tour right now. His former instructor was a huge proponent of the hip spin. He would have Mark literally work on standing there and seeing how fast he could spin his hips. Spin the hips, let the club fall behind you, swing on a flat plane, and somehow not hit it fat WHILE aligning the clubface for impact.

I've know a couple other students of this instructor (teenagers) and the amount of hip action they have is crazy. Stop at the top, hip bump, then SPIN! Throwaway city. You couldn't imagine the problems they have trying to get that out of their strokes even with proper instruction. It's so ingrained into their habit system that even they can't quiet them down. You literally need to attach their feet to the ground so they can't spin and push up. Needless to say many students of this school of thought move on when they realize it's effect on their games.
