RS2 Fly vs. Other Nymph Patterns: Which Is Best for Trout Fishing?

As a fly fishing guide with over a decade of experience on rivers from the Rockies to the Appalachians—and five years crafting content for e-commerce sites like Ascent Fly Fishing—I’ve seen how the right nymph pattern can transform a slow day into a trout-filled triumph. Trout don’t just nibble; they pounce on flies that scream “easy meal.” The RS2 Fly is one such pattern, a subtle yet deadly imitation of the mayfly emerger stage. But how does it stack up against classics like the Pheasant Tail, Hare’s Ear, or Prince Nymph? In this guide, I’ll break down the strengths of the RS2 Fly compared to these staples, drawing on real-world experience to help you choose the best pattern for your next trout adventure. Whether you’re ready to buy RS2 flies online or just curious, this article will equip you to fish smarter.

Why the RS2 Fly Shines as a Nymph Pattern

Let’s start with the star: the RS2 Fly, short for “Rim’s Semblance 2,” created by Rim Chung in the 1970s. It’s designed to mimic the delicate, translucent stage of Baetis mayflies—those blue-winged olives that drive trout into a feeding frenzy during hatches. What makes the RS2 so effective? It’s all in the details. A thin Antron or dubbing body suggests a vulnerable, freshly emerged nymph. The CDC or Antron wing adds subtle flotation, perfect for that “stuck-in-the-film” look trout can’t resist. A light hackle tail provides lifelike movement in the current. Available in hook sizes #18-24, it’s ideal for finicky trout in clear water.

From my guiding trips, I’ve watched clients land trophy browns on RS2s when dry flies failed, especially during spring and fall hatches. It’s a year-round performer, earning its spot in my top-five flies. At Ascent Fly Fishing, our premium RS2 Fly is hand-tied with high-grade materials for durability and realism, priced at just $1.65 each—a small price for big results.

RS2 Fly vs. Pheasant Tail Nymph: Finesse Meets Simplicity

The Pheasant Tail Nymph, crafted by Frank Sawyer in the 1930s, is the gold standard of simplicity. Its slim, pheasant-tail-fiber body and copper wire ribbing imitate a wide range of small aquatic insects, from mayflies to caddis. It’s a favorite for its no-fuss design and ability to sink quickly in deeper runs. The RS2, by contrast, is laser-focused on mayfly emergers, particularly Baetis, with a translucent body and delicate wing that scream “easy target.”

In my experience, the RS2 outperforms the Pheasant Tail during spring Baetis hatches on tailwaters like the South Platte, where trout key in on emergers struggling near the surface. I’ve logged days where RS2s outfished Pheasant Tails 3:1 in clear, slow water. But in murky, fast-moving rivers, the Pheasant Tail’s weight and streamlined profile make it a better choice for dead-drift nymphing. Want to hedge your bets? Try a two-fly rig with an RS2 dropper below a Pheasant Tail—trout rarely say no. You can grab our RS2 Fly to test this combo yourself.

RS2 Fly vs. Hare’s Ear Nymph: Subtlety vs. Bugginess

The Gold Ribbed Hare’s Ear is the ultimate “buggy” nymph, with hare’s fur dubbing that pulsates in the current, mimicking everything from caddis larvae to small stoneflies. Its textured body and gold ribbing create a lifelike, segmented look that screams “food.” The RS2, with its sleek Antron body and minimal profile, takes a different approach, focusing on the finesse of a mayfly emerger.

On freestone rivers like the Yellowstone, the Hare’s Ear is my go-to for summer stonefly drifts—rainbows up to 20 inches have smashed it in pocket water. But in technical scenarios, like late-fall sulfur hatches on spring creeks, the RS2’s delicate presentation fools wary trout that ignore bulkier flies. The Hare’s Ear is versatile but can wear out faster due to its dubbing; our RS2 Flies, on the other hand, are built to last multiple seasons. For anglers fishing diverse waters, both belong in your box.

RS2 Fly vs. Prince Nymph: Finesse vs. Flash

The Prince Nymph is the show-off of the nymph world, with peacock herl for sparkle, white wings for visibility, and rubber legs for extra wiggle. It’s an attractor pattern, perfect for murky water or high flows where trout need a bold signal. The RS2, by contrast, thrives in low, clear conditions, relying on its subtle profile to mimic a natural emerger.

On flood-stage rivers like the Madison, I’ve seen Prince Nymphs save the day with their eye-catching flash. But for tailwater browns sipping delicately in clear water, the RS2’s understated design is unmatched—it won’t spook leader-shy fish. If you’re fishing big water, stock up on Princes; for precision, buy RS2 Flies to nail those hatch-heavy days.

When to Choose the RS2 Fly Over Other Nymph Patterns

Based on years of guiding and testing:

• Pick the RS2 Fly for mayfly hatches (spring and fall), clear water, or when trout are feeding just below the surface. It’s a killer under an indicator or in Euro-nymphing setups.
• Choose others for specific needs: Pheasant Tail for deep drifts, Hare’s Ear for buggy versatility, Prince Nymph for high-water aggression.
• No single fly is king, but the RS2’s emerger magic makes it a must-have. Thousands of Ascent customers swear by it, and I do too.

Quality matters, so start with flies you can trust. Our RS2 Fly uses sustainable materials and comes with a satisfaction guarantee, ensuring performance when trout are rising.

The RS2 Fly takes the crown for finesse and hatch-matching precision, making it the go-to for selective trout in clear water. But the best nymph is the one you’re fishing when the trout strike.
