mine looked fine after 4 years and that was with no waxing, anyway before last season proshop guy told me to change it so i did, after 7 weeks of hunting and waxingit looked 100x worse than the original. so this spring i went to another shop and had another put on, shoots as good as new so i'll see how it holds up. when i asked the guy with the new string wtf with the old one he told me it was a cheaper dacron material, and said the new one was something like 4150 or something. not knowingwhat that meant he told me it had a much higher tensil strength. didn't know there was that much diff. between strings
