I've been using a nail knot tool for joining a short piece of leader material (mono/flouro depending on the situation) and so far that has worked really well with 15 lb braid and 12 lb Seaguar flouro leader. Well, I want to switch something a tick on the heavier side, maybe 20 lb leader material. I tried to tie a nail knot with the tool, and the knot was pretty big. Just wondering what other folks are using? I've looked at the Red Philips and sebile knots, but just wondering if there is a better solution.
