How many people actually sharpen park skis though. i could see it being useful on zero camber skis like the domains when trying to dig an edge in, but i wonder how it would effect edging on rails. might not feel as consistant or predictable
i suggest you do not buy lib tech skis if you are going to ride rails, within a season of riding the edge got ripped out of my jib nas, and is now cracked in 3 places. i cannot say anything about the performance of their powder skis but i found my skis had good pop on jumps and were very light on my feet.
I've loved my pow nas. They are definitely stiffer than I originally anticipated they would be. The only two gripes I've had with them is that I think they have too much sidecut for a 191 pow ski. They can hook pretty bad when hauling ass. The other is that they are damn heavy, but maybe that is the price for solid construction.
Construction has been burly though and the edges held up super well skiing an easy 50 days at Alta/Bird.
