Replying to Surface New Life or K2 Hellbent

So my old skis are pretty much trashed so I need a new pow ski. I'm 5'8, 130ish lbs and an expert skier mostly skiing Mammoth, but also a few Utah/Tahoe/PNW trips. I'm looking at both the 184cm 2011 Surface New Life (AB version-better graphic imo) and the 179cm 2011 K2 Hellbent. I'm leaning towards the Hellbent's because of the camber (I've never skied a flat camber ski). I'm worried about how the New Life's will handle on groomers getting back to the lift, but the New Life's are stiffer and will probably handle crud and chopped up stuff better. Which do you guys prefer? Have any of you demoed/skied both? Opinions?
