It also depends on what skis you want to demo. For Kastles, try Podium in Frisco. For Stocklis and often Blossoms, Gorsuch (in Vail, Avon and Keystone). For other near race skis or front side bias skis, try Precision on the main drag in Frisco. For widest selection otherwise, usually, try Christy's Sports in Dillon - a new, huge place in town, just off the main town road to Keystone/A Basin on the right (not the much smaller location at Copper Mtn, initially). If you use the Dillon Christy's, or one of their other locations first instead, you can also switch out same day for other top demo skis at any of their other, base of mountain locations, like the ones at Copper, Breck, Keystone, Vail and Avon. They can look up in seconds to find the location/store for any ski in their inventory.
