Plain and simple...nope they are not good. We have one down in Mississippi and the primary example for my answer is this...We followed an old Honda 250 into a Duck hole, he was pulling a Duck blind behind him and had the four wheeler in so deep water was pouring over the front hood. We were in deep as well but our belt got wet and started slipping and we almost didn't make it out with our brand new Polaris 325. He was literally running right past us on land and running circles around us with a trailer and duck blind in water. You get in a sticky situation where you want and hope your four wheeler performs and like it or not that Polaris belt fails to impress/perform when you put torque it. I used to see mud holes and head for them, with the Polaris you just hope you can get around it....disappointing
