I have an '04 ViperTec, with the original Limbsavers on, the older round ones for split limbs. I shoot my bow daily, and it seems to be louder lately. Does the NAVCOM material eventually wear out on these and need to be replaced. What I mean is does the constant vibration from shooting eventually degrade the material and they need to be replaced. I was thinking of putting on a new pair of the Alpha Shox, which I have on my VTec. I have checked very screw and nothing is loose. The bow was Crackerized this past winter and seemed quieter then.
