For the past 6ish years I have been shooting 10 strand, d 10, endless strings off my recurves and hybrids I pad the loops by serving them twice with nylon serving, I have no idea if that actually does anything but I haven't had any problems so far. I serve the nock area with Diamondback. The only reason I got into endless strings was because they looked easier to make and I'm limited on time. As far as string creep goes when I put a new string on a bow the brace height will drop and 8th or so in the first day or so after that I've shot one string for 2 years plus and the brace height never moves. This is off of bows in the 55Ib range.
