thanks arrow...

i use a length of fine sewing thread(about2.5 foot)wrapped arround the string on top(finished with a small dab of glue, looks like abrass nock only made of thread when done wrapping)anda small brass nock underneathe to keep my release from binding the arrow....its unconventional but it works, the thread doesnt move and lasts the whole year(when you keep it waxed).

i use the thread nockon my recurve too but i shoot 3 fingers under with that. it doesnt worknearly aswell with split finger shooting because the top finger rubs against it and wears it out.
