Karma and PE are both pretty stiff skis, the only time I rode the Fujatives I hated them more than any other ski I've ever tried, shaky, chattery and unstable was my experience, wouldn't ski them if you paid me to. The ARV's are a super nice ski for park, they butter smooth and are stable cause of the wide platform, whish also makes them float nicely in fresh snow, and cause you're pretty light they might work, but they are softer than both the Karma and the PE, so if you ski fast and charge hard you might overpower them, depends on the length you get though.
