Thanks for the answers.
So do you think I should get the 2010 147 Airobic or the 2010 or 2009 147 Evil Twin? I would probably get the riot but the smallest size it comes in is 151 which is to big because I'm 85 pounds. 65% jumps/kickers, 15% rails/boxes, 20% all-mountain/freeride
I'm almost twice your weight and I'm thinking the Evil Twin may be on the stiff side. (I'm more into freeride, but I want something easier to butter than what I have now.) I'd go for the Airobic based on your weight. That's assuming stiffness will be same next year as this year.
