Just got back from my third day now. Being in shape definitely helps and it's number 1, especially if "performance" is on your mind and you find good snow.
I'm not normally organized nor disciplined, but even so, the first days are about exaggerating the movements, for me. I'm too snow-happy to do many drills, but avoiding blacks, starting every run with a few super-phantoms, standing on the outside ski while maintaining a purposefully narrow stance, focused on relaxed but active feet and ankles, deep flexing to release and finishing with the skis across the hill while very counteracted were this weekend's cues. NSPP and outside pole drags are always good add-ons etc. Every run is just focused technical skiing for me, in the first few days.
noob - where did you go? Tremblant only opens next weekend and I'm thinking to get there the following... assuming it's top to bottom...
