Ya know I hate to say it, if I were you Id keep the warrior and get a 700. Little bit of an example from my brother, its slightly different but you will get the idea. He had a heavely modded 400ex, decided he wanted a 4 wheel drive. Now a year and a half later he wishes he still had the 400. In your case Id look at it as a back up quad or when you just want to cruise and relax. I do look at Red Headed Step Child as a buddy quad right now.
I plan on keeping a warrior no matter what else I were to get. Actually Im looking for a Wolverine thats ruff or needs some work. A 4x4 would be more fun at times, but Id always have a sport quad when I have a need for speed.
