I guess I'm spoiled and out of date. I don't have any software that can do frame by frame on a WMV file (hmmm - wait - maybe I do but my new PC is not Internet ready yet). I also like to make the victim a little larger in the picture when I tape. But I also use a telephoto lens. Anyone who can analyse this clip from watching a media player window has a great eye!
The first observation I'm going to make is that these are some very nice turns. You're getting on edge above the fall line, you've got a nice rythym going and a pretty smooth flow. I also see some good angulation as oppposed to banking.
In addition to that lazy left hand (held low and not doing pole swings), I'm thinking I'm seeing a little upward pop in the turns. It looks like your feet are a little close together at times, but at other times you have good separation.
On the right turn at 10 seconds in, you can see yourself launching the upper body into the new left turn instead of smoothly finishing the old turn. I suspect you did this on purpose to avoid skiing into the camerman, but it does hint that there's a bad habit lurking.
