i didn't get direct instruction in a long time and just got a cool one today - the best i've heard in a while.
ran into an older coach, one that's given me good advice in the past and i start bitching that, having just gotten the SL going, the long boards i just put on won't turn (my son's 20m skis).
seeing me ski that run, his answer was simple: of course they don't - because you're moving the wrong way: you're eager to turn them, so you move down and in!
it took a few more runs and by the time it started working, I figured i'm moving the exact opposite and he was completely right!
just a cool nugget of instruction i haven't heard before... not one you'll find in the books.
