I had a pair of the new Float-2's most of the season from Tom's. This spring I made a big order of shocks for several sleds and decided to upgrade mine as well and try the Evol-R. WOW! There is a huge difference. If you don't ride them you will never miss them, just because you don't know what your missing. I was very happy with my float 2's, but no comparison to the EVOL-R's. Everything is different. Silky smooth going fast on small chop, perfect rebound hitting big whoops hard and fast, exactly like a moto-cross bike would feel! Then on BIG drops, no bounce and no bottom out. Fast but smooth rebound without the bounce or kick. The Evol chamber is high pressure, 250 psi for the progressive portion of the shock, the shock body is low pressure, 60psi for compression, slow speeds and ride height. I hope this helps. Good luck!
Also, Tom is first rate to work with, so no hesitation there....I've dealt with him a lot.
