RIO Fly Recommendations | Hopper Dropper Combos from Kurt Kruger

Kurt Kruger, Far Bank Northern Rockies Sales Rep July 27, 2025

As we close in on August in the 406, our angling focus will switch from stones and mayflies to banging the banks with hoppers. While my preference is sending a single hopper into the wind, experience has shown me that adding a dropper pays out. It’s like betting on both red and black in roulette, except you don’t lose your second bet when you hit on the first.

The hopper-dropper routine is especially effective when fish become overly pressured by the Hopper Mob and stop fully committing to smashing terrestrials. Montana offers a bounty of different systems to play this game but my favorite is the Beaverhead River in Dillon, and then my home ditch, the fabled Gallatin River.

The following combos are hopper-dropper pairings that I throw with ultimate confidence on these two systems, but I’ve made may way around the Mountain West enough to watch them be effective in waters throughout the region and beyond.

A final note of advice: these hopper-droppers have very open relationships with each other, so don’t be afraid to switch them out with each other to keep things spicy!

All of these patterns can be purchased at the product carousel at the bottom of this post.

Combo #1: RIO’s Juicy Hopper (Tan #6 or #8) & RIO’s Morrish Super Pupa (Olive #14)

I like this combo early in hopper season when the fish are just starting to key in on the hopper profile and it seems that the majority of those floating the currents are a more drab tan in color. The Morrish Super Pupa in Olive is a nice complement that gets down thanks to a tungsten bead.

Combo #2: RIO’s Juicy Hopper (Peach #6 or #8) & RIO’s Hogan Hot Nest (Olive #14)

This is another early hopper season combo that really delivers. I like switching between the Tan and Peach Juicy Hopper this time of year, and the Hot Nest is a close cousin of the Super Pupa but without the tungsten head so I can feel confident tossing it into shallower seams without fear of getting hung up.

Combo #3: Chubby Chernobyl (Black & Tan #8 or #10) & RIO’s My Gal Sal TB (Yellow Brown #16)

The Chubby has become the skeleton key fly for big bug eaters. It could be a stonefly, a drake, or a hopper but this time of year and on these waters —especially in the Black colorway—it’s getting eaten by fish keying on terrestrials. I love to pair it with the My Gal Sal TB on the Gallatin. Even if the sallies are gone by now, the rainbows here just can’t help themselves.

Combo #4: Chubby Chernobyl (Chartreuse #10 or #12) & Sedge Hammer (Brown Olive #16)

Some years on the Gallatin and into September on other systems in the region, we’ll get some neon green hoppers and the Chernobyl in chartreuse is a great match. The bright color will catch some eyes and bring them in close, and Sedge Hammer dropper will do the rest. No one ever said a dropper had to have a bead! Pro tip: don’t dress this fly with floatant. Simply let it break the surface film and watch late season trout eye the chubby and nail the Hammer.

Combo #5: RIO’s Morrish Hopper (Pink #10 or #12) & RIO’s Hogan Two Tone Thin Thing TB (PMD #16)

When fish get picky and have seen every hopper in the bin as the season winds down, I like to throw the Pink Morrish Hopper. Its proven profile and the color change-up is just what the doctor ordered. And—especially if I’m on the Beaverhead and PMDs are still around—I love to match this with RIO’s Hogan Two Tone Thin Thing TB.
