I bought the Rossignol S6 174 cm 2010- 2011
Here is a picture:
This is the first of a 2 part review. I have skied 3 days so far at Gore Mountain in Northern NY on fairly firm conditions. The secon part will be done in late Feb on hopefully soft snow in Utah.
I am very pleased with the way they grip on hard surfaces. You can easily set an edge and carve a turn on firm snow. The ski is very stable and seems more stable the faster you go.
The wood core allows for soft landings when catching some air in the terrain park.
I found there is a drawback to the twin tip ski style and that is when getting in the gondola you have to ride up with the ski stuck in the snowboard slot.
I will edit this after my Utah trip when I have had a chance to ski it in powder -- (hopefully)
