go to evolution freeride at basin sports, they've got plenty of twins to demo for the day for 35 bucks or something like that, they've got a good selection
Both Aspen East, and Basin have demos for twin tips, and im pretty sure those are the only 2 shops that demo them, but Northern Ski Works might as well.
yeah, I was thinking they wouldn't have them but I was hoping I could try them sometime. not a ski I would probably buy but it'd be cool to demo them with all the hype they've gotten.
