I personally (my opinion) think that jib/cranes for skiing/action sports are a bit of overkill. It's almost like trying "too" hard to mimic what one would see as professional. Half the time the shots get ruined (same with dollies but that's a whole new topic in itself). Oh yeah and a dinky little 501/701 with some low end sticks won't hold this puppy, so that rules out this idea for most people... sorry I'm a dick.
On the other hand my opinion completely changes when the subject matter is somewhat cinematic (short films, even weddings, ect.)
Just not skiing.
Cool find though!
