I probably ski 60% park and 40% offpiste (keep in mind that I ski in Europe, where offpiste normally is 50cm at most).
I'll be mounting them with Marker Griffon Schitzo bindings (I know that many out here have something against them but just got my hands on a cheap pair and are going to give them a try for myself).
Rossignol Storm Open
If I could buy any ski I would probably go for the Line Blend or Armarda ARV - the softer parkski.
I'm 5'9, 147lbs.
