well how bout a change of topic here, although i think that snowest is great for info and have learned alot from guys like m5 who post on here.
I think you will find that polaris is much easier to toss around then the nytro. it takes a bit to get used to the way the steering is set up on them though. The engines make decent power but they have yet to make one that has held together (this being the 800). they only make it to around a 1000 miles or so then let go. (even with the updated engine)
Hope You have better luck with yours then my buddy's dad did, me personaly like the nytro better just cause its what im used and like the way the engine makes power.
