I have had two people suggest the Scott steering stabilizer over the GPR. Is there a difference in the technology? Why would you buy one over the other? I have heard about GPR's leaking, but I also got to ride a 2009 300 XC-W and the Scott's on it had leaked and was not working right. (The 300 XC-W was nice in the technical single track we were on, but the engine vibration has me headed for a 530 XC-W) Is it a difference between GPR & Scott like Yamaha vs. KTM, or KTM vs. Husaberg?
