Here are some of the best SL videos:
This is an older CSCF video of Marcel Hirshcer training Slalom. Excellent skiing and superb athleticism - some of the feats in there explain why he's been dominating WC SL for so long!
This is one of Mikaela's training runs. Great camera work, nice point of view.
A more recent training run from Marcel - again, different camera angles.
Tina Weirather freeskiing slalom turns. Some awesome points of view.
The race that put Dave Ryding in the top - the best technique on the WC, in my opinion.
