Incredibly profound yet fantastically flawed
Half pipe on skis isn't even interesting to me. Is there even a snowboard DH or slalom? Skis do ski things, snowboards to snowboard things.
There used to be am snowboard slalom, but I think they stopped it two Winter Olympics ago and replaced it with Boardercross. I actually did a couple of slalom races back in the day. The board set-up was different than on a regular ride, because you really needed to be able to keep your turns super tight or else you had no shot. I moved the bindings to point my feet much more forward than I'd normally do, and I canted my rear foot by inserting a shim (the point there was to keep you leaning forward as much as possible.) I was never very good at it, but I remember it being a pretty fun sport.
