[O.B.Left]

HB - I think that going from a bent knee position in the downswing to a straight left leg position at impact is nothing more than the O factor principle - as described by Robert Baker in his swing video lesson. It simply depends on how much of a positive O factor one wants to acquire at impact. Some golfers like Tiger Woods have a very straight left leg at impact (which is partially responsible for his left knee damage) while other golfers keep their left knee slightly flexed at impact.

I agree with Robert Baker that it is a good idea to have a positive O factor at impact, but greater amounts of O factor do not necessarily correlate with increased clubhead speed. One only needs enough O factor to get secondary axis tilt that allows the right shoulder to move downplane, which allows for the correct in-to-square-to-in clubhead swingpath when PA#4 releases the left arm into impact.

Jeff I like his pants and the green screen trick and all but only made it half way through "O FActor". Its hard to watch some of these things for me. I hardly ever read a Golf Digest anymore either. He made so many statements in the first half that I would disagree with that I had to turn it off. "Watch , as I speed my hips........." . Like he didnt swing harder with his arms......... so power is a zone 1 thing then?

"O Factor", the name is so derivative maybe and that is what put me off. "X FActor" , O Factor etc.

Factor this....Knowing of Hula Hula, pivot center, axis tilt etc how can you not disagree with his recommendation to tilt at address and set the head back in the stance as a normal procedure? This is a person recommending that you forsake centered balance, in the name of a what? A preset "O Factor" predicated on a misunderstanding of what it is that he is observing on tour at impact? "O FActor" address : Centered hips, but tilted by taking the head back into a wobbly off center position. You must see the implications to low point, balance, the necessity to slide into impact from there etc .............

This by the way is hardly new. I remember as a kid , copping Golf Digests recommendation to set the weight on the back foot at address to pre start the swing. There was a photo of Tom Wieskopf on the cover with his head set back and his shoulders tilted. His hips centered instead of his head. I hit a lot of hooks off of that stance.

Its 30 odd years on lets set the record straight. The uncompensated average every day swing has a pivot center between the feet.
