pros lifts the skis (can do this better with the powerclaw track got one and love it). con I did this to my sled and all I found it to do was trench in soft snow and get stuck quicker on a climb I put mine back after one ride. It trenches bad in soft snow. Went up agaist an 800 dragon and got my back side handed 2 me changed it back no other changes for next day same sleds and riders and outcome was totally opposite.
