Have any of you guys had a serving knot break or gut a strand of string? I am thinking of where the serving protecting the string at the string stop is tied off? I was shooting on Sunday and the serving started to loosen. I stoped shooting and had the local shop redo the serving for me on Monday. According to the shop owner if I shot any more I might have damaged the string where the serving tie-off, remember this is on serving that is not 100% in place any more, hits the string stop. Would like to hear the expert opinions.
