I would go for the 2014 and slowly upgrade it. I have had my 2014 since last September my first upgrade was the brakes. where I ride in the Whistler bike park elixer 5's just dont cut it. I went for Saints but if I was to do it again I would just get Zee's. My next upgrade I did was to switch out the Kage shock for the new 2014 Vivid r2c and all i can say is wow! Feels like a completely different bike sucks up all the small bumps. My Next upgrade will be to get rid of the Domain. It is way too heavy. A boxxer with the new charger damper is what I think I will go with.
