I ended up going with the Mnt. Tammer rear suspension! I was fed up with replacing upper spoked wheels and coupler block, on top of needing to replace the rear shock so I went for it. And it is very very nice!!!!! As for the float,a-arm and ski's it made a huge difference in the deep stuff and on the water. The float plate realy helped keep the snow from being shoved into the front of machine and steaming up air filter with water and loading the stearing with ice. A MUST! I was running my limiter I think in the middle to help it not trench as much and keep the front down while climbing. Hope this helps?
