So how bad are these things on hard pack and skied out moguls? I'm hearing a lot of bad things but can it still be done?

Pierre, Thanks for your question. The design of the ARG (true reverse camber) make it one of the best powder tools available. That being said it is just that, a powder/soft snow ski. Skiing the ARG on firm piste and through bumps is more hanging on, than it is skiing. This ski does not carve on firm snow surfaces, it pivots and slides. The overall girth of the ski is also a bit much to maneuver through bumps in my opinion. Can skiing the ARG in these conditions be done, for sure. I have been riding the ARG for three seasons. They are life changing in powder and soft snow, and life threatening skiing them on hard pack and through bumps in my opinion. I hope this is helpful for you.
