Im looking at getting a atv i used to have a scrambler. Right now im looking at at a few blasters and a few warriors, i like the size of the blaster and the fact that it is a two stroke, but i like the reliability of the warrior. Im leaning towards the warrior but im worried it will be hard for me to throw it around, im 5'2" 105 lbs, im used to my snowmobile which is huge (670 summit, 151 track) but dirt and sand are a little different.

should i go for the bigger machine or the smaller machine?

 

Neither machine should be too big for you especially if you can handle a snowmobile. The warrior may take less maintenance but the blaster will be easier to work on and usually cheaper to fix. Both are just about equal when it comes to speed but the blaster naturally revs faster and higher so it may be a little faster from a stop.
You shouldn't be worried about the size too much, your sled will be harder to maneuver than any sport atv. Even the 700cc sport bikes a fairly light

 

I think either would be fine, but the Blaster would be perfect for you if you like sporty riding. The Blasters are very reliable if treated right. Look for a '03-up so you get the better brakes.
