Hoyt Helix, QAD Ultra Rest, Axcel 5 pin sight. At each shot, im hearing a twang, like something is slapping something else. its not a vibration. I've made sure all bolts were tight, played with the string stop (might have to do this again?), and just re-timed the cams thinking that i finally found my problem, and... nope. still there. not as much but still there. is there anything else I can check to see if i can get rid of this sound? I know it won't be super dead quiet since its next to my ear but i feel like it could get better. Any suggestions?
