I just watched the 509 Evolution dvd again and I gotta say, to me its the best snowmobile video there is. I dont know if its the tunes, one legged wheelies, or who knows what else but its got so many cool little nuances to it that make it sweet. I know the winter it was made had serious good snow everywhere and that surely helped. How much time is spent matching up the tunes to the different segments and how that particular climb or whatever jives with the tune at the moment, it seems like in this one they match up just perfect.
