RE: Sims String Leech
moonge, man you get great life out of yours. I shoot a darton maverick and get around 50 to 75 shots at best. Never any more than that. I called them and they told me what to try and got up to 75 shots before distruction. They even sent me 2 packs as I was going through 2 packs a day when shooting so left them off during off season. But I wont buy them anymore. But they do work great.
