I have a 06 no boost Apex that I recently got the EZ Ryde and Extreme Challenger track, they set it for my weight, 190, with the front shock with no preload, I rode it in some decent deep snow and it went real good and rode smooth on the trail. I wanted to get a lighter feeling front so I tightened the front shock preload almost a inch, I rode it on some crappy/crusty snow and the front didn't feel lighter and it rode like a teeter/todder on the trail. Did I go to far with the preload or what. I'd call Dustin but they're closed, and its good to get other feedback.
