I had both cat whiskers and sims string leeches on the string of my Mathews Q2. The bow was very quiet. Today I cut the cat whiskers off and installed new string leeches. Now I've noticed more noise than ever. I never had string leeches alone on my string. Are they just not as effective as cat whiskers or did I install them wrong? Would it help to put the leeches closer to the nock? One of the leeches is not completely perpendicular to the bowstring as recommeded in the directions. Could this be why they don't work?
