My first post and figured I would chime in here. I registered here seeking info on my nephews blaster and decided I would join. I have a 700 raptor and there isn't anything out there I would get rid of it for. I have rode 400ex's and although there are smoother rides out there than mine I feel like I am in a big plush caddy to the ride of an ex. Keep the 660 and play at home on the blaster when you go somewhere larger take the 660.
