The reviews seem to be good, but I have never run them. A few of the guys at WOTR were running them on the trail we did. They loved them. I wouldn't hesitate to run a set.
Had a Jeepster with them, absolutely loved them. You float over everything you come to. It takes a little trial and error to get them dialed in but well worth the price and effort. My recommendation, buy them and don't look back.
I looked into them, but the more I researched and spoke with racers.. The valving is not so adjustable like others out there and the weight capacities are really low. Also the fading under extreme speeds and roads killed the spring rate. Also the price is a bit high, in that range there are other options.
Look into the ADS All in one Airshock/Internal bump stop/Bypass shock.
