Second thought, PaulyPaul just bought a new zuki450 and he loves it. He rides fast like the rest of us in our group and the last trip out to D he seemed to have NO problem with it at all. It's almost a size of it's own between the other 450's and the Raptor. The longer suspension helps a bunch in the ruff. He did mention you shift it alot, kinda like a 2 stroke. This is probably because it's geared for track. I bet if you changed out the sprocket(s), it would be great for the dunes. I guess you'd just have to ride the two and see for yourself, Jon. It's all personal preference.
