Sounds like you're looking for something with excellent edge hold, and
reasonably stiff. I'm about the same weight as you and also consider
myself
an "aggressive freerider" - carving, powder, steeps, trees, bumps... my
favorite soft-boot boards are the Doneks (www.donek.com).
Speaking of Donek, what's the score with their new board model(s)? I was
aware of a couple of names for it/them - Phoenix, I think? - but I haven't
heard anything for a while, and the website doesn't mention them.
