2009 martin cheetah. took some tension off limbs yesterday and have developed a "click" "tink" noise on the lower limb when i come to full draw. It is definitely audible and if i can hear it then the animals can hear it. don't know how to get rid of it. have adjusted the tension back and forth several times and nothing i do gets rid of the click. could this be a sign of limb fatigue because i shoot it at least 2-4 times a week for anywhere between 40-100 times
