I've used both RS and Manitou, and prefer the Manitou's. I have a '97 FS-Ti, which I've changed out the oil weight and the springs. I like the adjustability on the Manitous and the ease of rebuilding them. That and customer service is very helpful, they have sent me replacement parts free of charge. I also had a '98 Judy SL. I blew the cartridge within 6 months. It felt smooth, just not real reliable. When I rebuilt it, I was so confused, I had to have my wife try to help me because the instructions were so confusing. I finally got it all back together and blew the cartridge again in another 3 months. That was it for me no more Rock Shox. I am also seriously considering Marzocchi's as my next fork. Either last year's Z1 or Z3 with the QR20. Has anyone heard any bad reports on either of these?
