You guys try some fast flight bow string material you won't rip that apart like dental floss.
I always carry some dental floss, I break the plastic case it comes in and just carry the roll, like mentioned, I use it mainly for sewing thread and it works outstanding. I would double and twist and use it for fishing also if it came to it, seems to me it should work fine for drop lines on a trot line, or limb lines, but I have not tried it for such. Chris
