When I was 17 years old I picked up an issue of American Angler magazine. In it there was an article about a knot called the 16/20. The knot was apparently favored by an informal club in Canada where you need to catch a 20 lb Atlantic salmon on a size 16 hook to qualify. This article ended up being one of the most useful articles I have ever read. I have tried a lot of tippet to fly knots over the years but this knot has been the strongest for me in addition to being easy to tie. As a bonus, if you work on how you tie the knot you can limit your tippet use dramatically compared to most other knots. This video shows the way that I tie the knot. I hope it helps you out on the water.
