Well i have 2000 summit 700 151. and i am thinking about selling it an buying a newer sled. So here is my question. i ride alot around Drayton Valley (pretty flat). and i do ride the mountains about 3 times a year. i am thinking about getting a cross fire 800 or a m8. what are the major differences? i do enjoy climbing and playing in the powder. how well does a cross fire do up there compared to what i have now? what do you guys think?
