An SBD string with wool string scallops from Two Tracks (a sponsor here) will improve the performance and make every one of my bows quieter and smoother at release! And if for some reason I'm unsatisfied with the stealthiness of this combo, I'll use Bow Hush and Hush Puppies from our very own Terry Green. Works every time! I place the top silencer at the 1/4 mark, and the bottom at the 1/3 mark with either set up. This has worked so well for me, that I no longer worry about trying different strings or silencers. It is my go to set up, and before I tune any new bow, I'll install these first.
