I do not own a 600 IQ, however, I might be able to give you a little input. Last spring I had the opportunity to ride an early release '07 600 IQ for the day. I was quite surprised by the end of the day. The power was really good for a 600 twin, very notable midrange pull. Hooked up surprising well despite no picks. The best feature, however, was the handling. It was totally on through the chisel plowed fields and rough trail. Ride was comparable to my F7 Sno-Pro, except little better getting through the corners and much better ergonomics. I believe Polaris has nailed the ergos and that comes from having hours in the seat of a rev. The wind protection was also surpisingly good from the smallish looking screen. The only gripes I had was limited storage space and fuel economy (it was a carb model). These are quite minor considering the addition of an aftermarket bag and maybe some jetting might help economy. But then again, it takes fuel to make horsepower, kind of tradeoff. I think you will be quite pleased with your new ride. Do the snow dance and lets ride.......................
