If powder is what you are looking for, the Faction Ten5 will serve you well in the backcountry! The Ten5 is 100% freeride and floats superbly in the deep powder. But if you occasionally make some turns on the piste that is no problem for the Ten5. The Ten5 will deliver nice round, wider carved turns on piste and makes sideslipping turns just as easily.
Speeding through tracked snow is what little skis do better than the Ten5. The Ten5 has lots of stability and excellent absorption of irregularities in the terrain, a nice rocker construction and a very nice flex. The Faction Ten5 will bring maximum fun off piste and solid performance on piste.
