You can definitely go ahead and scratch the blaster from the list...Like loco said, it all depends on what you plan to do more often as to which quad to get. The 400ex will be good in the trails, but will probably get left in a drag. The banshee will be great for dragging, but will also need some work and skill to make a solid trail machine out of it. I ride my banshee 90% of the time in woods/trails, and the other 10% in dragging, fields, etc...It's real fun to ride in trails but is not as easy as a 4 stroke would be. A yfz450 would be ideal in your scenario though.
