Anyone have any experience with a Mars super? I just bought a 2002 model that was a pulloff at my LBS. I've played with the settings a bit, setting the air pressure at the recommended level keeping the stock coil spring in, but it seems too soft. I weigh about 180lbs, and run 150lbs of air in the thing. I run it locked out right now because it seems to move way too much unless im on pretty rough stuff. Anyone have any experience tuning these things?
