I have tried the Jax, string leeches, and catwhiskers. Not all catwhiskers are durable, but most are, and no other string product I've tried kills the noise and string vibration like whiskers. JME The newer leeches are more durable than older ones, but switching to whiskers has quieted down any bow that I've made the switch. I must add that I don't have a string suppressor on any of my bows. I had Jax on factory Pearson bows, and bought some for my son's Buckmaster G2 XL. I am not impressed at all with the job they do. Again, JME.
