Stryder, the W/E units really shine in the MX arena. A rider in a neighboring district runs them in harescrambles, and is very happy. He did have them revalved, but that's no big deal, and actually very common. Also, Rath has a very nice version of a ZPS setup. A local racer/Polaris Tech has them and has been very satisfied. If I don't switch to the Hot Seat titanium springs, I'll probably go with the Rath setup. Daryl's very smart, and fast.....and a great person to talk to. You could maybe check his site
www.rathracing.com and give them a call at their shop.
There has also been some concern about an earlier tip on removing the top-out spacer in the front shocks (when installing rezzi's). Some people have gotten on the net and claimed damage. I know half a dozen locals who have done this with nothing but great results, and the machines are mostly raced. I think the main item of concern is to make sure your suspension is setup so as not to be harshly bottoming out.
