I shoot a Hoyt Vulcan and I go through the factory string silencers rather quickly, although my latest ones have been on longer than the last two sets. Has anyone noticed a decrease in arrow speed without them? A buddy told me that he heard that taking them off will decrease the speed a few fps. Anyone else heard this? Also, would there be a big sound increase even though it has a string suppressor (like STS) on it? Any thoughts or ideas would be greatly appreciated.
