I've been using the Davy Wotten knot for all of my fly to tippet connections for about 6 years now. I can't recall a single failure attributed to the knot. As with all knots, you need to lubricate it before tightening. And, if you don't tie it right, it pulls loose when tightened. Even though it's the easiest knot that I have found and trust in, I still need magnifiers. But, you know what "they" say..."Gettin old ain't for sissies".
Give the Davy knot a try. You might be surprised.
Tight lines,
Bob
