I've tried almost everything LimbSaver offers to reduce vibration/noise with no success. All are well made but absolutely do not affect the sound or vibration. This universal cable management is their only product that really works and I use it everywhere. After a few hundred shots with each new bow, wire guides become noisy and harsh. In extreme cases, worn stock rails and rods stick so badly as to cause accidental overshoot to the right. Universal cable guides are always the solution.
