i hear that all the time about "getting into trouble" but i think that is a nonsensical statement especially as a qualifier on whether or not to get a larger engine or turbo or whatever. where a rider goes is entirely upon them besides a more powerful engine as long as you have the skill, can open up new riding areas.I'll give you that, the altitude makes a big difference. However I have a friend whos a guide in Wyoming, the company gives him a new sled every year and he can have whatever he wants. He usually gets a 600 because as he put it "its too easy to get in big trouble with an 800/850" He's been doing it for 30 years so I'd guess he knows what hes talking about. I did go out and ride with him for a weekend and I had an Summit 154 800, with the altitude it didnt feel like it had any more power than my 600 Renegade
i don't trail ride because it bores me to tears so i stick strictly to the mountains. we had some great snow conditions last year and i'm 250 geared up. there were a few times climbing in deep powder at 7k feet with the throttle pinned or close to it was needed on my '22 850 turbo to get to our normal riding areas. highly skeptical that a 600 could have gotten me there or at the least prolly woulda gone thru a belt or two.
