Episode Show Notes

The non-slip mono loop beat the double figure 8 on raw strength, breaking at 100.13 percent of line strength against 77.2 percent, but the double figure 8 is still my winner for the loop knot that pulls the straightest. In this How 2 Tuesday I tie both loop knots, which give your lure or fly more action, and break them head to head so you can decide which trade-off you want.

Frequently Asked Questions

Which is stronger, the non-slip mono loop or the double figure 8?

The non-slip mono loop won on raw strength, breaking at 100.13 percent of line strength while the Steve Huff double figure eight came in at 77.2 percent. That is a big gap, so if breaking strength is your only measure, the non-slip mono loop is the clear winner.

If the non-slip mono loop is stronger, why do you still like the double figure 8?

Because strength is not the only thing that matters in a loop knot. Even though the double figure eight broke lower at 77.2 percent, it is still my winner for the knot that pulls the straightest. A loop that tracks straight keeps your lure or fly swimming true, and that is worth a lot to me.

How do you tie the non-slip mono loop?

Start with an overhand knot six or eight inches down from the end. Pass the tag end through the eye of the hook, fly, or lure, then back through that overhand and bring it close to the eye. Wrap the tag around the standing line three times, pass it back through the overhand, snug it with the tag first, then finish by pulling it down with the standing line.

How do you tie the Steve Huff double figure 8?

Tie an overhand and pass the tag through once more to make a figure eight. Run the tag through the hook eye, up one side and down the other, snug it to the eye, then hold the tag beside the line, wrap twice, pass through both loops, pull the figure eight tight, and draw both figure eights together with the standing line.

Why does a loop knot pulling straight matter?

A loop knot that pulls straight keeps your lure or fly aligned with your line so it tracks and swims correctly. If the loop sits off to one side, the bait can run crooked and lose its action. That is why I still favor the double figure eight for straight pull even though the non-slip mono loop is stronger.

How many wraps does the non-slip mono loop use?

In this tie I wrapped the tag end around the standing line three times before passing it back through the overhand. Three wraps gave me a knot that broke at 100.13 percent, essentially the full strength of the line, which is exactly what you want from a loop connection.

Why I Tested These Two Loop Knots

Sometimes you want a loop knot to get more action out of your lure or fly, and two I like are the non-slip mono loop and the Steve Huff double figure eight. I wanted to know which one holds more strength and which one tracks straighter, because both matter. I break it down in the episode, so press play in the player above.

How to Tie the Non-Slip Mono Loop and Double Figure 8

Here are the steps I walk through in this How 2 Tuesday, with the full demonstration in the episode.

  1. Choose a loop knot for action. Tie a loop knot when you want more action out of your lure or fly at the eye.
  2. Start the non-slip mono loop. Tie an overhand six to eight inches down, pass the tag through the eye, then back through the overhand near the eye.
  3. Wrap and finish the non-slip. Wrap the tag around the standing line three times, pass it back through the overhand, snug with the tag, then draw down with the standing line.
  4. Tie the double figure 8. Form a figure eight overhand, run the tag through the eye, up and down the sides, wrap twice, pass through both loops, and pull the figure eights together.
  5. Pull each to failure. Break both loop knots to compare breaking strength, and watch which one pulls the straightest.

I unpack each of these in the episode. Press play in the player above.

Strength vs. How the Loop Pulls

The non-slip mono loop broke at 100.13 percent, basically full line strength, while the double figure eight came in at 77.2 percent. There is a real difference in breaking strength. But the double figure eight still pulls the straightest for me, which keeps a lure swimming true. I explain how I weigh that in the episode, so press play in the player above.

Final Thoughts From Me

If you want maximum breaking strength from a loop knot, the non-slip mono loop is hard to beat at 100.13 percent. If you care most about a loop that tracks dead straight, the double figure eight still earns its spot.

I tie both depending on what I am after that day. You can compare both of these to every knot I have tested in the free knot guide. Press play in the player above.
