If I were you I'd by the HFX Mag from Jensonusa, i think they're 145$ or something. I know it's 40$ over budget, but it's worth it. You should get 8" front and 6" rear. I know it looks cool. But it's not worth it for the rear wheel. How many times have you gone down a hill and said to yourself. Damn this 6" isn't locking enough, I need a 8". That and the 6" is lighter, a little less than a quarter pound.
