I've been boarding for a few years (actually, once or twice a year for several, and then 15-20 times last season), and my goal this season is to get my tree boarding going. I can make it through the trees when they're not too steep and the snow is nice and soft, but I want to handle them on steeper pitches and cut a nice line, because they're often the last powder stashes at the resort when we get a dry week. I also have a bunch of freeriding friends that get bored lapping the groomers.
This board has helped me out a lot with carving, giving me things to keep in my head as I'm laying down turns (angulate, rotate into the turn, flex/extend, etc). Any advice on where to start with tree boarding? As far as my setup goes, I'll be on an atomic radon, 25-something waist, 159cm long, on hardboots. What sort of angles/setback should I be looking at? I was thinking of running a kind of surfy stance, somewhere along 35f/20-25r.
