I know of3 different bows that have problems2 Matthews switchback I have 2 buddys that both have a 27 draw 06 switchback both of them on the cable on the cam about on inch above wears through the serving about every 6 months no big deal just have it reserved every few months. Matthews customer service blows it off. Now my 07 guardian 26inch draw has issues on the upper cam rubs the cable well the local dealer turned the cam filed and smooth polished the cam down so it would not hit the cable. Fixed and doesnt do it anymore.
