dental floss works but has two downfalls. You cant adjust it when set and it does seem to wear out relatively fast comparable to how much you shoot.
I used to shoot literally every day all year. My nocks would wear out or wear on the bow till I learned to tie them with #4 nylon.
Nothing detracting from dental floss as it works great, just be sure to saturate it well once its in its proper place or it seems to fray quite a bit.
Brass are nice too but growing up riding a bike it would dig into the riser section of my bowz. Plus you needed a tool. Simplicity is a glorious thing

. If its not broke dont fix it.
