its slipping toward the cam i marked the string with a black magic marker to know how far to serve . i keep pushing the serving toward the cam everytime it cracks open like 50 shots or so. this is on the power cable moves from center of bow towared the cam its a inch closer to the cam now. i rough up the string with steel wool and served tight with cam lock still going toward cam. also finish served with end of serving pull between stands hoping this would stop it. like i said before what gives? forgot to add yes serving the end loops
