But I haven't found any honest strength ratings. The surgeon’s is very strong on all differing sizes of leader—a triple surgeon’s is better than a double—but you MUST lubricate the knot with saliva and slowly draw the loops together for a smoother, more blood-knot-looking surgeon’s knot. I'd either go with the Surgeon's Knot or Albright Knot. Blood knot: two lines wrap around each other similar to the double uni … The uni knot is a good one, a palomar knot is also stronger than a clinch and my favorite for targeting big fish is the non-slip mono loop knot. The Uni Knot isn't quite as strong as the Blood Knot but it's a little easier to tie. If you’re attaching two quite different diameters, the blood knot may fail. Blood knot or Double Uni HANDS DOWN, the double uniknot is a better knot than the blood knot, especially if there is a line diameter difference between the two lines. I do not like the blood knot for connecting braid to a mono/fluoro leader (which is the only connection that the FG knot allows), so the FG knot is a big winner for that comparison. The Double Uni Knot is one of 12 great fishing knots included on the Pro-Knot Fishing Knot Cards (click to see).

As for blood knot for mono to mono connections, I believe it’s a good knot, but my preference is the double uni.

... Uni and Blood knots for hard ties, Lefty's little loop (nonslip mono loop) for floating connections. It is absolutely reliable in all classes of line and can be used with mono, braid and fluorocarbon. A Surgeon's Knot would probably work well and it's much easier to tie in these conditions that you'll face. The greater the line diameter difference, the more the The FG and J knots are stronger. Blood Knot or Double Uni? We put monofilament, fluorocarbon, and superline through an exhaustive series of tests and ­discovered the very best bonds for all

The Albright Knot is a good one and it's much easier to tie than the blood knot. That is used with large nymphs, streamers, salmon/steelhead flies etc and not only is it stronger than an improved clinch, the loop provides a swivel like action to the fly and makes it "lively".

Double Uni v/s Other Knots Easier than the blood knot.

The name leaves little to the imagination - two lines are joined together by two Uni Knots.When pulled taut, the Uni Knots apply opposing pressure on each other, and hold the knot in place. It is very strong and once learned it is also an easy and fast method of connecting a leader to your main line. Nail knot: use a nail or tube with an uni knot to tie one line around a second.

I assumed, like most, that the hollowed blood knot is the best line to line leader connection. What's the best knot for this setup?

FG Knot. It is easier to clip them short when they stand at 90 degrees than angling back like they do with surgeon's or uni-knots.

The FG Knot is a popular leader knot with sport fishing skippers in Australia and around the world. blood knot or double surgeon 07-03-2010, 07:22.

Fishing Knots: How to Tie the Six Strongest.

I also tried with double uni-knots. The Uni-to-Uni Knot is a basic bend knot for joining two lines of similar diameter together.
