Finally got to try these out. I purchased the 180 length with Dynafit TLT Radical FT. I'm 5'10" about 190 lbs. When I bought them I was looking for a lightweight, mid-fat do it all touring ski. The only resort skiing I plan to do with them is sidecountry. Conditions yesterday were week old Loveland Pass Backcountry junk. Some windblow, some breakthrough crust and a small amount of OK soft snow.
This ski felt exactly like it should to me. Lightweight, maneuverable, and easy to turn. I was impressed at the performance in the windblown and breakable crust. Given they are so light you would expect them to get thrown around a bit. They are bit squirrely at first, but then the dimensions kick in. The 133 / 105 / 117 really helps you plow through the junk. For me they offer a great compromise. You lose a bit of the plow through performance of heavier ski, but you gain so much in terms uphill weight relief and you gain in overall maneuverability. I also expect that the weight will help on steep, spring descents as well. It that case I would expect it to make them ski like a more narrow, heavier ski.
I'm sure they will be great in powder, but what 105 mid foot + ski wouldn't be :) . My concern was how they would perform in junk and on steep descents. I was pretty impressed in the junk. Not ideal, but given the weight, I don't think you could expect much better. Steep spring descents, not sure yet, but they have to be easier to ski than my 188 JJ's. I am confident that I should be able to ski anything I would ever want to attempt with these.
