Guess I am a little luckier. I use real small diameter shafts that require over nocks and over serts. So I use a dab of glue to hold them on. I do check before I refletch or occassionaly at range, but the glue seems to hold them fast. Only problem I have with nocks is if I get to showing off, and shoot two arrows at the same circle and they smack each other and break the nocks! [&:][8D]
