My 09 bengal is starting to show signs of wear on the serving well above my arrow. In line with it is the CCS so I am assuming the string is slapping the CCS. Is this a problem? I put a little wax on the area hoping it may cut down on the wear. I also had to do away with my truball double ball bearing because it was slapping the CCS and leaving a heck of a scratch on it. The CCS screws are tight too, I checked them. No problem for me to replace the serving every so often (not there yet) but just wanted to make sure there isn't a problem. Thanks.
