I didn't watch (youtube at work is problematical) but i assume its the same one that has been posted here before (twice, actually).

b) I hope there isn't a snowboarder adjusting his bindings halfway down
c) (seriously) it must be pretty hard to handle the transition to flat at the bottom - a sudden compression and change in drag
