The Strongest Knot For Doubling Over Braided Line [Knot Contest]

Braid Loop Knot

It’s knot contest time again!

Of all aspects of fishing, our knots are the only thing that we have 100% control over so it’s on us to make the time to ensure that we’re using the best knots for all of our connections.

And this is especially true for the connection on the weakest line in the system since the weakest link will of course determine the overall line strength.

This knot contest is focused on determining the strongest knot for anglers who like to double over their braided line so that their braid to leader knot strength is maximized.


One of the benefits of doubling over the line for saltwater anglers is so that the leader to braid knot can be stronger since there are two strands of the braid which is often at a lower listed strength compared to the leader for maximizing casting performance while having enough strength at the end next to the fish to withstand the sharp/rough mouths of many saltwater gave fish.

But the potential issue the line doubling knots create is a new weakest link in themselves…

So this contest is going to focus specifically on the line doubling knots to see which one is the strongest.

Here are the 4 knots that I’ll be evaluating:

  • Bimini Twist
  • King Sling
  • Spider Hitch
  • Surgeon’s Knot

And here are the lines used for this experiment:

  • 10 lb PowerPro braid (representing the main line)
  • 30 lb Berkley Trilene (representing the mono leader)

Note: I altered between the Double Uni and Yucatan knots for the final connection to the leader to see if either of them would bread before the line connector knot did.

Line Doubling Knot Contest Details

To test these 4 knots out for their strength relative to one another, I paired them up against one another in a tournament style bracket with the stronger knot going to the final round against the other winner.


The completed bracket is shown below.

For each head to head series, I tied them against one another on the same strand of line and pulled until the weaker one broke.

During the tension loading for breaking the line, I attached a scale on one end so I could log the strength on the line when the break occurred.

Then I repeated the process until 5 tests were logged.

Quick Assessment Of The Knots

Bimini Twist

This is known to be the strongest of all fishing knots. It’s strength is due to it doing a great job at spreading the load across a long series of twists without any sharp load bearing points.

Here’s a video I made last year (pre-beard) showing how to tie it:

King Sling

This is a knot that I was not even aware of before starting this analysis… I did some pre-experiment testing on a variety of knots and this one turned out to be surprisingly strong.

Spider Hitch Knot

The spider hitch is what many anglers use to replace the bimini twist when time is a factor. It’s much quicker to tie compared to the Bimini Twist.

Surgeons Loop Knot

The core design of the Surgeon knot always seems to make for very strong connections. Although it’s an extremely basic and simple design, it’s hold strength can often be one of the best for various connection needs.

Line Doubling Knot Contest Results

Here are the results for each of the head to head match-ups:

Round 1 – Spider Hitch vs. Surgeon’s Knot

To analyze which of these two knots creates a stronger connection, I made them both with 5 twists. This way, the most efficient design will come out on top.

Here are the results:

  1. Spider Hitch won at 13.5 lbs
  2. Surgeon’s won at 14.1 lbs
  3. Spider Hitch won at 15.1 lbs
  4. Spider Hitch won at 13.2 lbs
  5. Spider Hitch won at 13.8 lbs

Conclusion: The Spider Hitch is stronger than the Surgeon’s knot due to winning 4 of 5 bouts.

Round 1 – Bimini Twist vs. King Sling

To analyze these two very different knots, I kept the wraps equal to what I saw to be the typically directions from others websites/videos (25 twists for the Bimini Twist and 5 turns for the King Sling).

Here are the results:

  1. Bimini Twist won at 16.1 lbs
  2. King Sling won at 17.9 lbs
  3. Bimini Twist won at 14.1 lbs
  4. Bimini Twist won at 17.4 lbs
  5. Bimini Twist won at 13.7 lbs

Conclusion: The Bimini Twist is stronger than the King Sling

Round 2 – Bimini Twist vs. Spider Hitch

For this final round, I experimented with different amount of twists for each knot.

Here are the results:

  1. Bimini Twist won at 16.3 lbs
  2. Bimini Twist won at 16.9 lbs
  3. Bimini Twist won at 13.3 lbs
  4. Spider Hitch won at 19.1 lbs
  5. Spider Hitch won at 17.0 lbs

Conclusion: The Bimini Twist is stronger than the Spider Hitch, but it was closer than I was expecting.

So the winner of this contest was the Bimini Twist, which explains why it’s by far the most popular option. And although many people feel intimidated by this knot, it’s actually quite easy once you’ve done it a few times.

Overall Conclusion

This experiment proved that the Bimini Twist is the strongest of the line doubling knots that I’ve tested so far.


But although it’s by far the most popular, I was a bit surprised by how close the Spider Hitch and King Sling knots came from beating it.

And comparing the breaking range of the Bimini Twist to what the FG Knot did in the single line to leader test, I’m looking forward to testing them against one another.

As of right now, I believe that the FG Knot will be the victor since it was breaking at over 20 lbs in our last contest with it using the same types of line.

I’ll be testing them against one another using the same exact strand of line to make sure the difference isn’t from line quality.

Your Help Needed: If you use the Bimini Twist as part of your line to line connection, please let me know which knot you pair it with so I can make sure to include it in my testing.

Just a question, if you took all the results for each knot, and did a statistical average of break point and calculated standard deviation, what are those numbers for each knot? Might not change the results but based on seeing some break above 17 and below 13 for the same knot, its a wide variance. Would be interesting to see a table of all values for each test, I would be happy to run the analysis and share back the results. And of course the bimini and spider hitch with double the test results will have presumably tighter data set with fewer outliers.

Sorry if I got too nerdy on this.


Have you ever compared braid stitching with the bimini? It’s not feasible at low breaking strains but pretty easy in 50lb 4 strand (possible but more difficult in 50lb 8 strand).

I tried to run a relative test but the improved uniknot kept breaking before the knots I was trying to test.

John Lewis

Thanks for all the tips and tests you guys do. I usually tie.
my Bimini to my leader using a surgeons knot. I’ve never had a failure with it but would like to see the results if you should test it. Keep up the great work guys.

Walter Nowlin

I double my line with a bimini then attach my doubled line to leader with a slim beauty knot.

Vincent Foti

I really can’t thank you guys enough for your entire website and you tube channel!! Your time and knowledge of all aspects of fishing is very much appreciated

I’ve been using a loop to loop connection with bimini twists on both my braid (main line) and leader about 6′ of fl. Carb for years until I learned from you the fg knot. Great knot, hasn’t failed yet.

Howard Bessen

For the doubled line to leader, I think the “improved Bristol knot” (sometimes called the “modified, modified Bristol knot”) is great. Sort of like an Alberto knot in reverse (wrapping the mono around two strands of braid vs. the opposite). Owner of a tackle shop in Cabo San Lucas (Baja California) told me that this is stronger than the Yucatan knot, which many of his customers use. (Have you posted you results yet? Would like to see how the FG knot fits in …).

JI'm BIcknell

I use the Aussie Quickie. I would love to see how it compares in your contest.

Cecil Daniels

Great videos. Love to have a quick chart on the boat for others to see with test results. I use an Albright special for Bimini to leader, but I love the FG knot the way you demonstrate it. Can’t wait to see how it compares.

Douglas Ely

I had always used double line at the terminal end to act as a “shock absorber”. This has been since I started fishing when all we used was mono. Now with the advent of braid, I have been using a single strand of the braid attached to a fluorocarbon leader. I have liked using your FG knot to attach the two but it does let go eventually after repeated casts (I have read your troubleshooting suggestions and I do pull very tight before use). Could the FG be used to tie the fluoro to the braid if the braid had been doubled?

Barry Taylor

H ave you ever plaited a double? I hav’nt tested a plait with a Bimini Twist and I use both. With braid I prefer the plait while Mono I stick with a Bimin Twist.i

Bill DeWeese

About darned time. Bimini Twist for the win! My absolute favorite, default knot for terminating the main braid line. Combines wonderfully with the Aussie Quickie to attach leader to the Bimini.

If I could make a recommendation, I would do a video showing how to tie the Bimini knot using the reel handle. This is not just because the handle and any other fixed object like the chair are similar, but tying on the rod/reel is far superior as it allows the line on the rod to provide tension on the line. This tension serves as a third hand and makes a complex knot like the Bimini, crazy easy to tie.
