RE: what stand?
I love my Lone Wolf Alpha Assault. It's just 8.5 pounds, one piece cast aluminum (silent and light) and easy to hang. Although I would choose to get the Alpha (not Assault) model for the bigger platform now (12.5 lbs).
I don't think I would leave one up on public land, though...too expensive.
The Lone Wolfclimbing sticks are great, too (10 lbs for 4 sticks, which gets you up 15'+ in a tree), and they fit nicely onto the stand for easy, compact carrying.
