Re: Nail Knot
IMHO, the easiest good-quality leader-to-tippet connection is nesting clinch knots (aka, the basic bluegill bait hook fishing knot). Bend the leader over to form a "U" and tie an improved clinch knot on that U using the tippet. Then turn it over in your hand and repeat by tying an improved clinch in the leader onto the tippet, moisten, and snug the two knots together. It's quick, it lays down completely flat, and everyone should be able to tie the knot in their sleep. Pretty decent knot strength too.
