Why on a flat is this important important? Even on a flat, Once I start to get speed and angulation comes into play, don't I get vertical seperation?
SMJ - this will tie into your MA - I promise!
What we're talking about here is the ability to move the legs independently. We see this as a common element in higher level skiing. Yes, too much weight on the inside ski can cause problems. But the difference between the static exercise and real skiing is that the forces of the turn will help to transfer weight to the outside ski. IMO, vertical separation comes from the pitch of the slope - this is where the distance between the feet is greater than the distance between the legs. No matter what the pitch of the slope is, you'll get greater vertical separation from greater stance width.
It is possible to make turns beginning with both legs extending, both legs retracting or one leg extending while the other retracts. For the type of turns seen in this video clip, independent leg movement makes for more efficient turns. If there is a slightly wider stance width and more use of long leg/short leg then there will be less vertical movement in this skiing and more effective use of the ski edges and less of a need to direct the skis across the fall line. Changing from one leg long to the other leg long allows the hips to travel from one side of the skis to the other without changing vertical height and transfers pressure to the new edges earlier in the turn.
