I am traveling to Alta for a 4 day weekend and only have really heavy, racing skis at home. I could take these, but am a pretty skilled skier and plan on going into the back country and side-country areas. I have been out west multiple times and am able to do these safely. Is it easy to demo skis at Alta? Or rent? Also, if renting, are the skis good quality? I want to be able to use good quality skis for the time I am there.
