It's a reasonable notion Ott; a single still frame can be very deceiving. We've all seen stills that catch world class racers in some pretty ugly poses. But even in these shots the reality that this is a very good skier in a bad moment does seem to make itself known.
And to the opposite side of the coin, I've never seen a shot of an average recreational skier that has fooled me into thinking I was observing a world cup athlete. The presence (or absence) of skill, and a comprehension (or ignorance) of technique has a way of shining through even in a single frame.
My impression of the two pictures is that Jamie has a basic concept of balance, body position and edge control, and usually feels comfortable on his skis. His friend, on the other hand, looks as though his prominent sensation while skiing is probably one of feeling unsure, out of balance, out of control, and just generally confused as to how the hell to make those damn shape skis turn the way he'd like.
Ott, I'm not saying that Jamie has reached a technical pinnacle; just that he seems to have progressed very well in his short time on skis. This is not so unheard of. I've seen some very rapid skill development achieved by naturally gifted athletes. I've also seen skiers who've been at it for years still struggle basic technical skills.
Bottom line; my money is still on Jamie.
