Had the opportunity to ski these for three days at Mammoth, first two on 8+" fresh and wet, the last on ~4" windbuff. I'm 6'1", 180#, and went with the 192s.
Great tree skis that turn quickly, stable at high speeds and on hard/packed/choppy, long and big enough to land drops smoothly, just all around awesome. I was most impressed at how quickly they turn at low - moderate speeds and how easy they were on my legs, especially for the first weekend of the season and how damn big they are.
Overall, my first impression was very positive, and I would recommend these skis for anything resembling powder. If my opinion changes after more use I'll update this review.
Size wise, the 192s are perfect for me, but I'm biased towards longer skis. Do keep in mind that nimbleness and fatigue wise they feel like a much shorter ski.
