From the specs Vince gave, it has the Premier's spade tail, but is blunted. From eyeballing it, it does appear to be slightly more narrow. Could be due to the setback sidecut though.
As far as handling, you can whip the tail around much easier than say the Proto. I was riding it on Bosses and Hail boots and found it very responsive when whipping in and out of turns.
Wolfie obviously rode legit powder with it. I rode a few inches of neglected pow stashes in random areas and the Cobra was surfy. I wouldn't say this is a pow specific board, rather an all-mountain board that handles the pow very well. I'm hoping to be able to get out West next season with this thing and push it.
