Atomic Ritual - 182cm, 130/103/119 (19m radius)
They're cambered, have a little tip rocker, and an average amount sidecut. They seem to have a medium-stiff mid-section with soft tip and tail, which makes them very easy to maneuver when off piste. When on piste it feels like only about 60% of the ski -- the central portion-- gets much bite. That mid-section is stiff enough that it should allow a decent carve, but I'm guessing that my demo pair had dull edges. The skis are light, aren't at all damp, and don't give much rebound.
I had a blast using them on a powder day at Whistler. I think they'd be a splendid AT ski. The only wide ski that I've used which might be better for AT is the K2 Sidestash, which is stiffer, damper and more rockered.
Head Sacrifice - 181cm, 144/105/131 (16m radius)
They're cambered, have a little tip rocker, and a lot of sidecut. (And Head greatly reduced the turned-up tail when the Sacrifice replaced the Inferno.) Their flex is medium-soft, they're pretty damp, they have some rebound, and have decent edge grip, so they carve pretty well for a mostly off-piste ski. They have a round flex (unlike the Ritual), and on-piste it feels like 90% of the ski engages with the snow. They feel like a lighter, softer and less damp version of the very damp Head Rev 105 (which is no surprise since they have the same dimensions).
I didn't get to test them in powder, but given their flex and my experience on the Rev 105's, it's easy to conclude that they'll steer through powder like a dream. Those who want to pivot or slarve won't be so happy, though.
I'd recommend these to lighter skiers who want a wide 70% powder - 30% on-piste ski that isn't fully rockered.
Salomon BBR 8.9 - 186cm, 147/88/110 (12.5m radius)
These are pretty good carvers! It feels like about 70% of their length bites the snow on piste and they have good edge grip, medium stiffness, and a smooth, damp feel. So on-piste they ski like a short carving ski for an "advanced" skier.
I never got a chance to ski them off the piste, but given their amply-rockered, super wide tips and medium stiffness, they're probably pretty easy to steer in powder and tip-dive won't be a problem.
There's also a wider, stiffer version of the BBR, the BBR 10.0.

How well you are able to ski is related to how hard you are willing to fall.
