I see some talk on knot tying tools for nail knots...I've been tying a nailless nail knot for all of my line/leader connections. An old fly fisher showed me and i've used it ever since. takes about 30 secs to tie, no tool required and i have never had trouble with it slipping. For the kind of fishing i do(bass, gills, trout) it seems to be adequate.

Any one else use this?
