Introduction
The Copper John is a fast-sinking nymph pattern renowned for its versatility and effectiveness in imitating subsurface insects. With its weighted copper body, lifelike profile, and rapid descent, it’s a must-have fly for anglers targeting trout and other fish species that feed on nymphs.
How to Tie the Copper John
- Hook & Weighting: Start with a short or medium shank hook and add a tungsten or brass bead head for extra weight.
- Body Construction: Wrap copper wire tightly around the hook shank to form a dense, cylindrical body. Add wire ribbing for segmentation and durability.
- Thorax & Wing Case: Use peacock herl for the thorax to create a contrasting texture. For the wing case, secure a thin material like Flashabou or Thin Skin over the thorax and fix it behind the bead head.
This streamlined construction ensures the fly sinks quickly while maintaining a realistic appearance.

What the Copper John Imitates
The Copper John mimics a wide range of aquatic insects, including:
- Mayfly nymphs
- Stonefly nymphs
- Caddisfly larvae
Its generalist design makes it irresistible to fish, as it suggests multiple food sources in one pattern. The weighted body and natural movement enhance its effectiveness in turbulent or deep waters.
Best Places & Techniques to Fish the Copper John
- Water Types: Effective in rivers, streams, lakes, and ponds, especially in deep or fast-moving water.
- Fishing Methods:
- Dead Drifting: Let the fly sink and drift naturally with the current.
- Swinging: Allow the fly to swing across the current to trigger strikes.
- Nymphing with an Indicator: Use a strike indicator to detect subtle takes.
- Adjustments: Vary depth and retrieve speed to match fish feeding behavior.
Why the Copper John is a Must-Have Fly
- Fast Sinking: Reaches feeding zones quickly.
- Versatile Imitation: Works as a mayfly, stonefly, or caddisfly mimic.
- Year-Round Effectiveness: Produces results in all seasons.
Whether you’re a beginner or an expert, the Copper John is a reliable fly that consistently delivers results. Add it to your fly box and experience its unmatched effectiveness on your next fishing trip!
Introduction
The Czechmate is a purpose-built weighted nymph designed specifically for the Czech nymphing technique, a highly effective method for targeting trout in fast-moving waters. With its rapid sink rate and lifelike profile, this fly excels at reaching the feeding zone quickly and triggering strikes even in challenging conditions.
How to Tie the Czechmate

- Hook & Weight: Start with a heavy jig hook (size 10-16) and a tungsten bead for maximum weight, ensuring the fly sinks swiftly to the riverbed.
- Body Construction:
- Use dubbing or synthetic material in natural hues (brown, olive, gray) for the body.
- Add ribbing wire for segmentation and durability.
- Realistic Profile:
- Overlay the body with thin skin to create a sleek, natural silhouette.
- Unlike traditional Czech nymphs, the Czechmate features a pronounced thorax made of peacock herl or other reflective materials to enhance visibility underwater.
What Does the Czechmate Imitate?
This versatile fly mimics a range of aquatic insect larvae, including:
- Mayflies
- Caddisflies
- Stoneflies
By adjusting the size, color, and profile, anglers can fine-tune the fly to match local insect species.
Best Waters & Conditions for the Czechmate
- Fast-flowing rivers & streams – The extra weight ensures quick descent to the strike zone.
- Freestone rivers, tailwaters, and spring creeks – Effective across diverse water types.
- Cold-weather fishing – Particularly deadly in winter and early spring when fish are less active and reluctant to chase food.
Why It Works
The Czechmate’s rapid sink rate, realistic profile, and high visibility make it a must-have for nymphing anglers. Whether you’re fishing deep runs or pressured waters, this fly delivers consistent results by staying where the fish feed.
Tie some up, hit the river, and experience the Czechmate’s deadly effectiveness for yourself!
Introduction
The Stimulator is a buoyant, highly visible dry fly prized for its versatility and ability to provoke strikes. Whether imitating large terrestrial insects or aquatic hatches, its bold silhouette and floating properties make it a must-have in any fly box.
What It Mimics
This adaptable pattern can represent a variety of insects depending on size and color:
- Stoneflies – Its robust profile and segmented body closely resemble these large nymphs and adults.
- Caddisflies – When tied in smaller sizes, it mimics fluttering caddis adults.
- Grasshoppers – In terrestrial-focused fisheries, its buoyant design and leggy appearance make it an effective hopper imitation.
Carrying Stimulators in multiple sizes and colors ensures readiness for diverse fishing scenarios.
How It’s Tied
The Stimulator’s construction is key to its effectiveness:
- Hook: Long-shank dry fly hook (sizes 6–16).
- Body: Bright, coarse dubbing, often ribbed with wire or thread for segmentation.
- Tail & Wing: Deer or elk hair provides buoyancy and enhances the fly’s silhouette.
- Double Hackle: A palmered hackle through the body and a front hackle create lifelike leg movement and superior floatation.
- Head: A bullet-style wing and reinforced head cement ensure durability.
Where & How to Fish It
- Ideal Waters: Fast-moving rivers and streams, especially during stonefly or caddisfly hatches.
- Techniques:
- Fished dry on its own in turbulent water.
- Paired with a dropper nymph for a two-fly setup, increasing strike opportunities.
Why It Works

The Stimulator’s combination of buoyancy, visibility, and lifelike movement makes it irresistible to trout. Whether you’re targeting aggressive surface feeders or prospecting in rough currents, this fly delivers consistent results.
Pro Tip: Experiment with sizes and colors to match local insect activity—its adaptability is its greatest strength.

Introduction
The Diawl Bach is a subtle yet highly effective small nymph pattern designed to target a wide range of freshwater species. Its slim profile and realistic imitation make it a favorite among fly anglers, particularly in clear water conditions.
What It Mimics
This fly is crafted to imitate a variety of small aquatic nymphs and insects. Its slender, segmented body closely resembles natural prey, making it an irresistible target for trout and other freshwater fish.
How It’s Tied

Tying the Diawl Bach is straightforward but yields impressive results:

- Tail & Legs: Hackle or pheasant tail fibers enhance movement and lifelike appeal.
- Variations: Some tiers add a bead or thorax cover for extra weight and attraction.
Where & How to Fish It
The Diawl Bach excels in all freshwater environments, particularly in clear water where fish are selective. It can be fished effectively in two primary ways:
- Indicator Nymphing – Suspended beneath a strike indicator for controlled depth.
- Euro Nymphing (Tight Line) – Fished with a weighted line for a natural, dead-drift presentation.
Why It Works
Its simplicity, versatility, and realistic profile make the Diawl Bach a must-have in any fly box. Whether you’re targeting wary trout or aggressive panfish, this fly delivers consistent results.
Final Tip
Experiment with different sizes and colors to match local insect hatches—adjusting bead weight can also help fine-tune sink rates for varying conditions.
