I have a buddy that owns a ski shop and started skiing on a pair before they came out for retail sale, and he skied them all last winter. He backcountry skis at least 4 days a week, but since he owns a shop he skis different equipment all the time, but his main setup had he Pures. I have been out with him at least 4 or 5 times when he was on them. We skied all kinds of conditions and he never had any problems and claimed that he liked them. He has even skied the area a few times with them. He is a pretty agressive skier and weighs about 185 lbs.
It is a little suspiscious that when he did the Haute Route at the end of the winter he took a pair of boards with Freerides on them. I'll see if I can get some better info from him for you.
