I have the pipe nas [check profile pics for the ones] if thats what your looking at, backcountry lists them as park nas. i havent ridden them yet but plan to next season, they are on the stiffer side. heard the edges are super strong [from sean jordan cuz he use to have em] and that the topsheet chips easily but havent heard anything on delam.
My friend has a pair. Not too serious of a park skier but rips for sure. Does a lot of natural stuff. He loves them. No delam/breaking as far as I know. I mean they're made by a snowboard company so they kindof have to be pretty durable right? THey've got magnitraction too which is sick if you know what that is. Definitely a sick ski though If you're thinking about getting them and can find them go for it.
