i've ridden both quite abit and i must say you can't go wrong with either. i feel the SL is quicker pushing out of turns and feels slightly more nimble. the blur is much more plush and really handles the technical stuff better. i would catagorize the SL as a XC/Racer and the Blur as a trail bike/all purpose, no to say you couldn't use one for the other. OH YEA NO COMPETITION GET THE V10

ps i bought the blur
