I have the Polaris ones and I love the look and how easy they were to install. They offer pretty good protection as well. The Guru bumpers are supposedly the better of the two options, and I have never heard a member disappointed with them. If I was harder on my machine I'd go Guru, but I just don't like the look of them. (Yes, I am one of those wierdos that likes a certain look! LOL!) No regrets with the durability of the Polaris bumpers though.
