I also have an lx that makes a popping or clicking noise when I draw back but only after I shoot, I found that the string was comimg out of the roller on the cable gaurd, the cable gaurd was not machined correctly, it had a 1/8" space between the rollers & the back of the gaurd, put a new string & cable gaurd on & it works great. I never have had the string stick to the string suppresor, I also don' t
wax my string serving, Mathews needs to check there machining better.
