I was bouncing around on Youtube for a video to refresh my memory on serve wrapping, and stumbled across at least one youtuber who swears by monofilament fishing line for serving thread.
He didn't specify 6 or 8 lb test or whatever, but he talked about how it doesn't fray and it's slick and flexible (and if you use a string nock point, you can adjust it by screwing it up and down).
I have serving thread now, but whenever I run out, I'm tempted to give it a try.
What do you guys think?
