I can get hold of some carving videos (hardboot snwboarding) form a hardboot guy I bought a board from - those videos are sweet. In fact I think Todras has my video, although I'm not sure.
Personally, I'm sick of the mainstream snowboard videos. All they have is teenagers in oversized snowgear, with their pants around their ankles, jibbing off handrails and crap.
There are some of those guys who actually do some heli-boarding, and that stuff is cool, but it's always a snippet of that kind of footage surrounded by hours worth of stupidity.
