atomic is coming out with a new ski for next season called the blog...115mm underfoot, 10mm tip/tail rocker, and super stable at speeds, even on hard snow. if youre willing to wait, itd definitely be something worth looking into. i gotta plug atomic first!
otherwise, obseths or something of the like would definitely be a good pick...good in the deep snow and stable enough to rip on.
otherwise, something 100+ underfoot, twin, not fully rockered for better stability at speed, but the tip/tail rocker idea is definitely a lot of fun in trees and lower-angle deep stuff.
