I shoot on average 3.5 times a week for about three hours all year average including hunting season, for 17 years now . I don't know if that is more or less than anyone. L don't change mine reguarly but I have had strings give me sign of changing so I did change them. Like axle to axle lenght changing. Strings un twisting on me. If I get a couple of good seasons on them they will fray near the serving from hitting my winter clothing. I only shoot Winner Choice strings, they have 100% serving on there Buss cable so they last a long time. My set is $107 for the string and cable.
