My Allegiance destroyed the string silencers in the first 50 shots. I do not plan to do anything until just before hunting season. The 3D targets don't care about 1 or 2 decibles more noise. I have discussed this with the pro shop and we agreed that the Simms would do the same thing the originals did. We are going to put cat whiskers on in the fall. Good luck and let me know if you have good luck with the Simms.
