vibration
#3
I switched to a carbon fiber guide rod and it also took alot of the vibration away. I have never used one of those though. Guide rods tend to bend slightly especially with heavy pull weights and the carbon fiber rodsseem to dampen better than the alum. or steel rods. Plus they are lighter too boot!

Yes they absolutely work. I can notice a definite decrease in noise when I install one. I install mine so it just does touch the cable slide when the bow is at rest. This way it stops the slide and absorbes the vibration in the rod and the slide at the same time.
