Double Up for Fly Fishing Success

Two is better than one when it comes to chocolate brownies, contact lenses, and trout flies. If you’re looking to increase your odds of catching trout, then double up. Use a lead fly and then a second fly, which trails behind it a foot or so.

Here are some double-fly combinations that really work. They include wet-fly combos, dry-fly combos, and dry-wet-fly combos. You never know which fly the trout may prefer on a given day:

1. The Hopper + Terrestrial

This is great for late summer during hopper season. Start with a size 6-10 hopper pattern—or some kind of large attractor pattern (such as a Stimulator). Then, trail either an ant or beetle pattern behind it. This is basically a dry fly combo, although it’s fine if your dropper (the ant or beetle) floats below the surface in the film. Last week, I was fly fishing in Colorado and talked to a fly fisher who used this combo in a high mountain lake and caught fish after fish on size 14 beetle pattern.

2. The Elk Hair Caddis + Caddis Emerger

This is a dry-wet fly combination which works well in the late spring (when the Caddis start to appear) and then into the summer as the Caddis flies continue to emerge.

I like a size 14 or 16 Elk Hair Caddis as my dry fly. Then, I use some kind of an emerger pattern as the dropper. One of my favorite droppers is a size 14 Red Fox Squirrel Nymph. I’ve had great success with this combo on the Yellowstone River in Montana’s Paradise Valley. With this combo, your lead fly acts as a strike indicator. I’ve often tied some synthetic red or white fibers at the top of Elk Hair Caddis so I can distinguish it from all the other Caddis flies on the water.

3. Woolly Bugger + San Juan Worm

My podcast partner, Dave, put me onto this combo. It’s worked well for us in the Driftless region of southeast Minnesota and southwest Wisconsin. This is a wet fly combo. Start with a smaller-sized Woolly Bugger (8-10) and then use a San Juan Worm (tied on a size 8-12 scud hook) as dropper. I use a strike indicator and drift it like a nymphing rig. Then, at the end of the drift, I will swing it and strip it back to me.

On the swing and strip, it’s the Woolly Bugger that is effective.

4. Egg Pattern + Copper John

When I’m fly fishing during the rainbow spawning season in the spring, I’ll often turn to this wet-fly combination. I’ll begin with a standard-size egg pattern (12-14) and then use a size 18 Copper John as my dropper. I like a Red Copper John. Or, I’ll use a Dave’s Emerger. This fly was developed by Dave Corcoran, then the owner of The River’s Edge Fly Shop in Bozeman, Montana.

Regardless of which dropper I use, this combo has been lethal during the rainbow run on Montana’s Madison River. It can work, too, during the fall when the browns are running. But continue reading for another dynamite wet-fly combo.

5. Stone Fly + Egg Pattern

Dave and I used this last fall in the Gardner River in the north reaches of Yellowstone National Park. We had outstanding results. Start with a Stone Fly nymph pattern (size 8-10). The options are legion.

A Golden Stone Fly or a Rubberlegs Stone Fly (with a brown or tan body) works quite well. Then, use a standard-size egg pattern (12-14) as the dropper. Last fall, I had a 30-fish morning on the Gardner using this combination. The browns were all between 15 and 20 inches. I estimate that I caught half on the Stone Fly and half on the egg pattern.

6. Beadhead Prince + Pheasant Tail

This wet-fly combo, or some variation of it, may be the standard go to pattern when there is no obvious hatch.

Use a Beadhead Prince Nymph in a size 12-14 as your lead fly. Or go with another standard nymph such as a Hare’s Ear. Then, use a size 18 Pheasant Tail as your dropper. Again, your dropper could be any number of nymphs—such as a Copper John or Zebra Midge.

Remember, two are usually better than one. Try one of these combinations or experiment with some of your own. You’ll likely double your chances of catching the trout which are monitoring the food line you’re fishing.

  1. Great combos, I like to use a bead head prince nymph with a Frenchie. The AuSable ugly (Adirondack modification to a wooly bugger) and a Frenchie. Waltz sulfur nymph and you guessed it, a Frenchie. The Frenchie is in my opinion the best nymphing fly ever. I like to rig my tandem flies euro style. Tie on your point fly, heavy fly(the fly that will be on the bottom), then tie on a short piece of tippet about 18″ – 20″ above the point fly using a double surgeons knot. Use the tag end that points to your first fly and cut the other one. Tie on your 2nd fly. I like this tag end to be 4″ – 6″ long. Any longer and you will get more tangles.
    Don’t be afraid to try try new things. Have fun. Fishing 2 flies is an amazing experience.

  2. Ok. I am a new guy to this. But is there a special way to cast this dropper without it getting all tangled into something that resembles fly line. The only way I have found is to water load and then cast, nothing fancy. Any other suggestions?

    • Great question! Yes, water load and then cast without alot of extra false casts is the best suggestion I can give. It’s also worth reminding ourselves to let our backcast unfurl all the way before we bring it forward. But too much false casting seems to be the main culprit when it comes to tangles.
