I have only been riding for 4 seasons no expert on the subject. But I like Hybrid Rocker with + camber under foot & rockered nose opposed to traditional cambered board.
I ride in the north east (upstate NY) conditions I ride in are mostly hard pack, PP, LG but we get occassional powder dumps now and then of several inches to 2+ feet of snow per event thanks to lake effect. been riding trad camber until week ago. huge difference for the better w/+ camber underfoot to tail & rockered nose (very popularfree ride shape now find it on the Burton baracuda & many freeride boards now) board very easy & quick to turn flys over bumps & tracked out pow where Trad camber tends to dig in superior float in the pow & can ride with more upright stance all this and near equal if not equal edge hold (I got 2012 Atomic Banger 162 I'm 5'8" 140)
