Well Jim....how often "the little O appears between your knees is something that's a blog all to it's own.
But the technical aspects of what you brought up I believe are key factors in creating good carving skills. Improvement in these areas add awesome ski skills to the tool bag and skiing moves to a whole new level.
Now...get to work on that little O.....and I'm guessing there's many reading that may prefer the bigger "O"!? 

? G
"O" I don't know that this is true.? I was always led to believe that size doesn't matter?

Good to have you back, BTW.? How was Whistler?
I thought of you when Rich (and later Diana) told Lynn how elegant some of her turns were. (Actually, Diana's comment was that "your turns today aren't as elegant as the ones yesterday on the blue terrain".) You have contributed a lot to those turns.? Its interesting that if challenged she can ski pretty fast, but that certainly isn't her preferred mode.
You missed some of the greatest video.? As I'm being filmed, I ski by with lower legs vertical and torso a bit behind that.? As I go through the turn I am literally in a sitting position but still skiing.? Three frames later I am on my butt and the skis are no longer connected to my feet.? In real time, I had no idea why I fell; on the video I was so far back that I couldn't believe it.? Very enlightening (and humbling).? I never envisioned that I was that far back in normal skiing, no wonder
you and Lynn and Phil and Ron and Greg kept trying to get me forward.? I think I will tie
string rope from my knees to the toes of my bindings.? That will at least keep the lower part of the leg forward (but might make it tough to get the boots out of the binding at the end of the day).
