Replying to Capable Rails?

So this doesnt deserve its own thread, but where else would i put it? Sittin in my dorm at IU we have at least 6 inches of snow left. I have already hit up a real mellow 35' rail and a dub kink...there are tons of rails to hit, but the rest are all aluminum....I have heard skis dont go well with aluminum, and i really dont wont to go the effort to build a lip and see for myself...does anyone know first hand if aluminum will slide well with skis?
