soupcanFrom what I have heard from a friend about the lib tech stuff is it is a very fun playful ski and the magna traction works very well on groomed and what not but the edges gets damaged very easily on rails due to fact it's kinda like a serrated knife. This is not from my first hand experience but from a friend and a guy from a local shop but they both seemed to share the same opinion on them so there must be some truth to the matter.
Demo'd the lib techs for a couple runs a few years back. Haven't rode their later models but I was VERY impressed with them. They hold an edge like no other its pretty crazy how well they work.
I didn't take them into the park though but they struck me as more of an all mountain charger than a park ski with the edges.
