Looking at buying a 2016 snowmobile having trouble on brand. Im really looking at a Arctic Cat m8 limited but been thinking about a Polaris 800 rmk Pro. Like not having so much weight and more options. But unsure about durability and build quality in the Polaris. Like Arctic Cats new clutches also. Don't like the not having track options though. The engines on Polaris are iffy to me to. Haven trouble deciding. Any help?
