If I were you, I would go with what thewholetruth mentioned, and look into the PANO. thats what I would get if I had the money. It shoots to solid state cards (good for action sports, cause you won't get drop outs like you do with tape. Secondly, it uses DVC Pro, which I believe is around 100 mb/sec (dont quote me) opposed to DV & HDVs 25 mb/sec data rate. The pano also haas the option of recording at 60fps, so if you want to get that sick slow mo shot of a switch cork 9, you can shoot in that mode and then slow WAY down without notcieably loss of quality. I live in tahoe, and ride northstar everyday, and I am seeing more and more panos and less and less HDV. I rode up the lift with a guy who shoots for think thank (dont know if youve heard of it) but he was tellin me that this is probably the last year that most of the snowboard production companies are going to be shooting film, and that most of them are using the panos now.
Mawk Dawg productions threw down for FOUR of those R.E.D. cameras (80k, no biggie) so that shows you the importance of resolution in action sports, I think your best bet would be with the pano. check it out, I think there is a new one coming out soon, or it might already be out.
Hope this helps you out, keep in touch you sound like your in the same boat that I am. anyways, peace out and good luck.
