This guy. Good to know when you're on the river trying to milk every inch of your leader and you don't have an extra leader in your bag.Building leaders?! People still really do that!? Who the heck wants a hand tied leader with a bunch of knots.
I still use a double surgeons knot and have for over 5 years! Caught 15# carp on that knot, I agree that an extra loop is not worth the extra bulk you get from a triple.
I think I will try this blood knot with bigger tippets.
