Servus!
Had to pipe up on this one....
To Ben: you have been misinformed my friend. Rock Shox only has elastomers in their low-end model, the Jett. One you get to Judy, you are talking about open oil bath springs.
To Trekn: Judy has a proprietary spring system using a stage one and stage two, coil spring in each leg in a lubricating oil bath. SID uses a sealed volume of compressed air that is used as a spring medium. So, difference is steel coil spring vs. air as a spring medium.
I ride a '00 Judy SL and am quite pleased with it's performance. I have replaced the springs with a custom set that is suited to my weight and riding style. Have had much praise for Manitou in the past, as well.
