Dude seriously, if you're on a rail, it doesn't matter what skis you have on, and when you crash or have run-outs into the street, you can still do the rail without worrying about wrecking skis you paid a couple hundred dollars for.  If you want twins just heat up the tails, bend them, and go. It's what I do.
