I am impatiently wiating for winter to start. Picked up the 2012 obsethed 189 this summer. Just looking for all reviews of fellow riders who have been on the 2011 or 2012 chassis! Specifically, what do you think of their performance through the bumps? When I'm not in the trees, or high alpine, the bumps are where I tend to be. Curious on what you all think of their versatility!
