Silver Star is fairly smooth overall (except for Dag's and Downtown) so you can get away with a steeper, shorter travel bike (a girl we go with rides a Giant Trance and does quite well) but if you also plan on hitting resorts like Kickinghorse, you'll want something more slack with more travel.

BTW, haven't ridden Revy yet (will this year though) but Martha's Creek is supposed to be an amazing shuttle run.
