I have a couple days on the Crimson ti, this ski really rips on hard snow. Excellent edgehold, stability, has some pop out of the turn, haven't had much of a chance to ski them off piste except in some heavy refrozen stuff, and they got deflected a bit in that stuff, but not surprising seeing that it's is a stiff ski torsionally. It's a great carver though, and I have to say, my 183 blows away the 186 Head 88 I had a couple years ago as far as edge hold, carvability and stability at speed. The Head was more forgiving, and likely better off piste though. I did find a patch of a few inches of untracked, and the Ti made some nice smooth carves, but can't make much of a judgement from that.
The ski likes to be driven, not a ski to relax on as much as some. The first day I thought they got deflected a bit like some others reported, but the second day I didn't notice it much, so I chalked it up to snow conditions. They were also fun in the bumps and pretty good in trees, but that's where the refrozen stuff was so it's hard to make a definitve judgement there. I got the ski for days when it hadn't snowed in awhile, and so far I'm happy with them, after my second day of skiing, I couldn't wait to get back out, but will have a better idea when I use them in a variety of conditions. I'm 5'11, 155.
