Just looking at the skiing, I think that this is a function of the technique rather than the ski. The ski isn't helping balance-wise in the top of the turn, but I wouldn't place all the blame there. You usually don't start to see a clear development of the top of the turn until you get into the 40-50 point racers though - especially in women.
Since Hulluva opened the door, let me try something way above my pay grade and talk about a technical aspect of Liz's skiing. As many of you know, I've been programmed, some say brainwashed, over the past 5 years to avoid extension movements in releasing the skis. The up-movement is clear in her skiing and at the top of the turn, I don't see how she can begin to hook up her skis as extension has pushed her body away from the snow and she would be light. Yes or no? Once she comes down and brings the skis to edge, she rips and carves the place up far better than I.
Josh, do you have similar video of you doing this type of carving. From looking at stills, my sense is that you do use more flexing in the release portion of your skiing. How do you teach this aspect of a turn?
