The Strongest Knot For Doubling Over Braided Line [Knot Contest]
By: Luke Simonds on November 17, 2016
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.
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
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:
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:
- Spider Hitch won at 13.5 lbs
- Surgeon’s won at 14.1 lbs
- Spider Hitch won at 15.1 lbs
- Spider Hitch won at 13.2 lbs
- 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:
- Bimini Twist won at 16.1 lbs
- King Sling won at 17.9 lbs
- Bimini Twist won at 14.1 lbs
- Bimini Twist won at 17.4 lbs
- 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:
- Bimini Twist won at 16.3 lbs
- Bimini Twist won at 16.9 lbs
- Bimini Twist won at 13.3 lbs
- Spider Hitch won at 19.1 lbs
- 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.
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.
