I see what you're saying, I think I've rode basically the same sled - my brother's Indy 500 SKS. It's about 75 HP, 3/4" lugs, gearing and clutching that's still trail-oriented, and on and on. You need a crust or pretty wet/heavy snow for one of those to get around off-trail. Starting with the Gen II, and especially when you got into the bigger EDGE and iQ sleds, you had enough power and track to get around, it's just that things were baked in to the chassis that make it want to stay flat to the snow. Comparing my EDGE to my Pro, besides the power and track disadvantage, it takes more effort and is less predictable. On deep days, a 600/144 is going to be a stuck mess, but on the typical snow I see, it gets around fine. As it gets less deep or more springlike, I find the 600 can actually be more fun. Anyway, if you've got money to burn, newer and bigger is great, but anything's better than sitting at home looking at the snow out the window!
