I ride a 2006 700r...I chose it because i wanted something that could haul... like stoopidbot said...i like to go fast too...although the type of terrain around here would be better suited with a utility I still love my raptor and i dont think i would trade it for anything..it has all the power and torque of the 450's plus it has reverse and reliability...(not saying the 450's dont) but my raptor has about at least 175 hours on it and its still running as good as new... I think that the real reasons of choosing a sport quad are because there so fun to throw around ,you can go up pretty much any sand hill around and mostly they haul....
