(VIDEO) Three Great Ways to Create Tag Droppers

by | Sep 20, 2022 | 16 comments

Fly anglers like to fish with a couple flies once in a while. The standard method for attaching a second fly is run it in-line — as a trailer from the bend of the first fly. Instead, I prefer to create a tag dropper for that attachment. Tag droppers have big advantages that I’ve detailed in this popular Troutbitten article from a few years back . . .

But maybe just as important is how we create the tag for the dropper. And I have three favorite ways that I use for different reasons and specific applications.

Watch the following video, and then find more detail in the paragraphs below.

The Splice

Joining two lines and leaving a long tag on one of them is what I call the splice, and it is arguably the most popular method for creating a tag dropper.

For joining these two lines, I choose the Orvis Tippet Knot, and there are a couple of good reasons. First, this knot saves material from the mainline, because we create the tag with the added-in length of line. Second, that line also creates a tag that points up and away from the mainline, instead of down. And this difference provides a real advantage for keeping lines tangle-free.

Blood knots are fine for the splice, but they can get a little tricky in skinny tippet diameters. And they provide no advantage over the Orvis Tippet Knot. Likewise, the Double Surgeon’s knot is a fair choice, and probably the most popular, but it requires the use of the down tag, which is created by the mainline, also shortening that by the inches required to create the tag. Using the added-in line with a Double Surgeon’s Knot, which creates an up-tag dropper, is a mistake, because it forces knot breakage on even medium-sized fish.

Use the Orvis Tippet Knot, and love your life.

The Layover

What I call the layover is a close cousin to the splice, because the tag dropper is created by the exact same motions. Here, I choose the Orvis Tippet Knot again to create the tag. A Double Surgeon’s can also create the layover, but you must — once again — use the down tag.

The layover is a great method because it preserves the original length of the mainline. It also maintains the strength of the mainline, and I’d have a hard time arguing that it’s not stronger than the splice.

Lastly, by using the layover method for creating a tag dropper, I can add thin droppers on a thicker line. For example, think of using 4X to a tight line drop shot rig, then using 6X to create the tags for a pair of #20 Zebra Midges. You get the strength of 4X to the weight and the flexibility of 6X to the flies. It’s a neat trick.

An Orvis Tippet Knot and the up-tag.

The Add-On Line

This third method allows for the creation of a tag when a knot already exists on the mainline but no tag is present. With the add-on line we create a tag and slide it down to the knot.

To create the tag, simply tie a uni-knot around the mainline above the existing knot. Snug the uni-knot, but do not tighten yet. First, slide the knot into position, and then tighten it down.

READ: Troutbitten | Fly Fishing Strategies — The Add-On Line

The Uni-Knot here cannot be beat. Because there are five wraps around the mainline, it’s a much stronger knot than choosing a Clinch, a Davy or something similar. Those knots have only one wrap around the mainline, which can sustain damage and break easier. (Trust me. I learned the hard way.)

The Add-On line is a great choice for saving time and saving materials.

What About Loop Droppers?

I hate ‘em. 🙂

While loop droppers are the classic solution for creating tag droppers, they are also the worst. They are clunky, they slide, and they take more time and material to form. No thank you.

But if loop droppers work for you, don’t let me change your mind.

Take Your Pick

With three good solutions for creating tag droppers, there’s a method for every moment. And by getting each of these under your fingers, by practicing them and being comfortable, you’ll find uses for all of these methods as you work up a river.

Fish hard, friends.

(VIDEO) Fly Fishing the Mono Rig — Casting vs Lobbing

Turnover is the fundamental difference between spin casting and fly casting. And all good fly casts, with fly line or otherwise, allow the line/leader to turnover in the air and then hit the water. That’s the difference between casting and lobbing. Without good turnover, we are simply lobbing the line.

Remember this: lobbing is limiting. And a good casting approach, with great turnover, introduces a wide range of options . . .

Podcast: An Introduction to Night Fishing for Trout — S3-Ep14

Ambition is the fundamental characteristic of every good night fisher. We wade into the darkness for the experience. And we quickly realize that the night game is an unwritten book, with just a few clues and an infinite room for learning new things. Each exhilarating hit and every trout in the net is a unique reward, because night fishing requires that you assemble the puzzle yourself.

In this episode, I’m joined by my friends, Trevor Smith and Josh Darling, for an overview on night fishing for trout . . .

Casting and Drifting | Drop Shot Nymphing on a Tight Line Rig — Pt.5

Gaining the bottom, feeling that contact with the riverbed and then gliding over it, tap, ta-tap, tap-a-tap, maybe five to ten times throughout the drift is success. But I’ve noticed that anglers tend to get complacent. Tickling the bottom is only half of the job. And that’s not good enough. We still need to find the right speed for a drift and keep everything in one seam.

Drop shotting puts the angler in ultimate control. Be aware of every element of the drift, and make good choices, because all of them are yours. Control is the advantage of a drop shot rig. Remember this always — your rod tip controls everything . . .

A dead drift is the most common presentation in fly fishing for trout, because it imitates their most common food forms. We want a dead drift on both a dry fly and a nymph. But what is it?

It’s a one-seam drift that travels at the speed of the current without tension from the attached tippet. That’s hard to achieve, but it is possible by first understanding what a dead drift looks like, both on the surface with a dry fly and below the surface with a nymph . . .

This wading staff system makes strong waders stronger and fast waders faster. It allows all waders to reach even more water.

If you rig a wading staff the wrong way, it slows you down. But if you rig it the right way, a wading staff opens new worlds and speeds you up.
It gives you access to places that you couldn’t wade before.

But it has to be rigged the right way . . .

  1. Like so many I’m steeped in the surgeons knot mantra. I am however forcing myself to break free from it and deploy the Orvis Tippet Knot. I’m a lousy knot tier though and fumble through the learning curve until I can obtain some semblance of muscle memory. At this point I sometimes fall back to the surgeons because I’d rather fish than fumble. What are your thoughts regarding double, triple, or even quadruple surgeons knots with a 6x tipppet?

    • Hi Joe,

      Do you use all three methods of adding in a tag dropper?

      Regarding triple and quadruple surgeon’s: I find the extra wraps useless and completely unnecessary. If I tie a good double surgeon’s, I don’t need the extra wraps.


      • Thanks Dom- I typically use the layover method as I primarily Euronymph. I do use the add on line method occasionally.

  2. Great stuff as always Dom! One nuance I’ve found is to use a thicker tag when using the layover method.

    For instance, if my main tippet is 5.5X to the point fly, I’ll use 5X for the tag which gives me a little more separation, less tangling, and a stronger knot at the tag.

  3. Thank you, Dom. I am a better angler because of what I learn from you.

  4. Have you ever tied a dropper off the tag of a blood knot? The blood is a clean little knot and easy to tie. Dave Rothrock promotes the use of a blood in a dropper rig in some of his videos. I like the know for joining tippet sections but wold be concerned about knot strength if tying a dropper off the tag (and which tag would you use?).

    I am a double or triple surgeon’s knot junkie, slowly weaning to the Orvis tippet knot because of the advantage of the up-tag (I have lost medium sized fish using the up-tag of the surgeon’s knot).

    But while we are having the discussion, I would be interested in the experience of others with the blood/dropper set-up.

    • Hi Eric, I mentioned the blood knot in the article above. It’s a fine solution. It just takes a lot longer to create a tag with a blood knot in thin diameters, and there’s no advantage over the Orvis Tippet Knot. In fact, I believe the Orvis Tippet Knot is actually better than the blood knot in the way I can use the up tag.


  5. Agree the Orvis knot has advantages… and like having the “up tag” so why do we have to use the bottom tag after the Uni knot dropper?

    • Good question. Because using the up tag on a uni knot just pulls the wrong way. It cuts through itself.

      Don’t take my word for it. Give it a try for a while, and you’ll probably see it too.

  6. Hello Dom I must say a great explanation of three very practical, efficient and strong methods of tag attachments.

    Thank you for sharing

    Tight lines, AJ

  7. Awesome info. If you have a longer tippet than you want, one thing I do that saves a little time is to use the end of my leader as the new tag. By tying a double surgeons I end up with a long loop and just clip that loop asymmetrically to leave an appropriate length tag and the rest remains the leader down to the point fly. I end up with your “layover method” but I didn’t have to pull a new piece of tippet off. Take it for what it’s worth and thanks for the info!
