Ive used them since 94 or so. They work well. You will here all kinds of pros and cons from people. "The Scotts is better" "The GPR is better" and so on. They are also more expensive. People say that they like the Scotts or GPR because you can adjust on the fly. I just set the WER and forget it. Im not sure about anyone else but Im not in the habit of taking my hands off of the bars at high speeds to adjust a damper! Drew Smith, the guy that makes them is a great guy with lots of knowledge and a has multiple ISDE finishes under his belt. He owns WER. Great suspension shop too!
