So last night went to the bowshop to get a different launcher put on my QAD so i could shoot FOBs, and my bow guy took one look at my serving on my string and said what the heck. He ended up replacing most of my serving on my main string due to excessive wear and seperation. The worst part was the serving that sits on the idler wheel. It was pretty much worn into multiple pieces getting real close but not wearing on the actual string itself. He said its cause of the deep groove idler wheel on my 2010 Bengal. I thought it was cause of how much i shoot. Any thoughts? Guess i should mention i shoot roughly 200 arrows 1 to 2 times a week.
