[Weightshift]

One other thing

It's impossible to overdo the Slide, so long as you're playing between the insides of the feet (I'm told that Ken Venturi had specially made golf shoes which were higher on the outside edges. God knows what they were like to walk with though.) and the knees point slightly inwards. In the backswing, when the hips can move no further to the right, they start to turn -- in fact this is what causes them to turn. Similiarly at the end of the backswing / start of forward swing, the hip slide to the left causes the left hip to turn when it can slide to the left no more. There should be do conscious thought of turning the hips, in either direction.

Of course it's possible to overdo the Slide if one is not playing from the insides of the feet, in fact it's almost guaranteed.

The silence is deafening I'll retract that the hip slide to the right causes the the right hip to turn -- simply because in trying to emulate Tomasello's teachings, he starts the backswing with turning the right hip.

7-17 FOOT ACTION Foot Action accommodates the Knee Action resulting from the motion of the Weight Shift, and accepts the changes in the loading of the feet. The loading can shift between the inner and the outer edge of the foot but shouldn't roll the Foot over on its edge...

I guess it's only the outer edge that is being referred to here. I still believe that in practice, at least, purposely standing with pressure on the insides of the feet, is good. Wider stances permit better such feel (but narrower stances, less weightshift action, obviously). I was watching Julie Inkster on TGC who appears to have a fairly narrow stance even with the driver, and an almost imperceptable (sp?) forward weight shift.
