Never ridden Blue Mountain and too far away to do a pre-ride. It would be awesome if someone could give me some insight into the overall terrain or course description. Especially if you raced it last year, I realize the course might change too.

Skill wise I'm not worried about the terrain but if it's a course with some good size rock features and/or loose rocks and/or steep difficult to navigate sections, I would choose my 10lbs heavier bike just because it won't throw me over the handlebars or break in half
