I assume you meant Quick Carved Turn...ie QCT?
And I assume skiatansky is being sarcastic, as obviously this entire thread has pointed out the differences, over and over.
Of course it is complicated as the SVMM crowd is still struggling to pin down exactly what their QCT actually is.
But in a nut shell, the SVMM guys seem to be showing a forward pivot point/tail push turn initiation mechanism created by applying tip pressure from pushing the shin into the front of the boot. This can be seen with a "closing" (or indeed just staying locked forward) of the ankle in the turn initiation phase. This move transfers the skiers mass into the boot cuff, which then relises on the boot stiffness to transfer the skiers weight to the tip. This is slow, moves the pivot point forward resulting in the tail being displaced laterally, preventing carving, and it moves the skiers mass forward of the feet putting them in unbalanced state reducing their ability to react.
Of course some of the skiers in their videos , highlighted in Post 263, dont do this at all, and as a result get wicked ski performance. What they do, is what everybody does, (or at least strives for).
That is modern skiing advocates a centered pivot point under the foot, turn initiation is created by tip pressure, however that pressure is generated by pushing on the ball of the foot, resulting in instant transfer to the skis tip, this can be seen by an "opening" of the ankle in the initiation of the turn. It doesnt require the skiers moving forward, allowing the skier to stay in better balance meaning they can react better (If you dont get this, there is an excellant right up of this in Warren Witherels book "The Athletic Skier". There is at least an entire chapter dedicated to this, it talks about how our ability to naturally react, is effected by our balance state.) It also enables uncoupling of the fore/aft/up/down/lateral moves allowing for expert level pressure control and edgeing to happen in the bumps.
In a nut shell the difference from what SVMM shows and how the rest of the world ski is in the turn intiation mechanics.
