I think I actually owned the school bus of sleds. When my son got too big to ride in front, we bought a 2002 Arctic Cat 660. That was before the turbo. That thing weighed more than a Ford Ranger. It was a great sled for bringing the boy on rides though and was comfortable, got good gas mileage and ran like a top. However, I wouldn't even have wanted to do loops in my backyard for fear of getting that tank stuck in more than 6" of snow! It does point out that different sleds are right for different times in our lives. That one worked perfectly for my needs at the time. The 900 NA works great for me now but there was a time when it wouldn't have. Honestly, any sled that lets me get out in the woods in winter is what works. I don't look at anything as a compromise as long as it lets me ride.I have never owned one.
I also haven't owned a school bus but I know I wouldn't want one.
