Episode Details

Episode Overview

The Butcher Shop goes deep on one of the Great Lakes predator fly world's most distinctive patterns in this conversation with Eli Berant, the Michigan-based fly designer and founder of Great Lakes Fly. Eli is the creator of the Optimus Swine — a reverse foam head-embedded, side-kicking musky streamer that has been turning heads and producing fish since around 2009. In this episode, host Marvin Cash walks Eli through the full arc of the pattern: the lake musky problem it was designed to solve, the unconventional decision to reverse a foam popper head to create a slower fall and a pronounced glide-bait wiggle, the material choices that define the fly's profile and movement and the step-by-step construction logic from spinner bait hook to laser dub head.

The conversation covers the full Swine family — the original 8–9 inch version on a 6/0 Mustad, the scaled-down Swine Junior for river smallmouth and stripers, the fettuccine-foam Pot Belly Swine for subsurface river applications, and the articulated Maximus Swine and Maximus Swine Junior, which remain something of a "secret menu" offering. Eli also addresses color selection by region — from olive-and-pink for fired-up Tennessee muskies to the Wisconsin-proven Willen's Villain black-white-yellow combo and his own favorite Mardi Gras pattern — and breaks down his preferred line and leader systems for lake musky versus river smallmouth applications. Throughout, the discussion grounds fly design theory in direct, tactical fishing application.

Key Takeaways

• How reversing a foam popper head toward the rear of the hook creates a slower fall rate and induces the Optimus Swine's distinctive side-to-side glide-bait action.
• Why proportionality in bucktail application — specifically how much material per section and how many sections — is the most common failure point for tiers attempting the Swine for the first time.
• How to tune the Pot Belly Swine's fettuccine foam piece by removing individual strips to achieve neutral balance and proper swim orientation before fishing.
• Why a jerk-strip retrieve with a sinking line (350–450 grain tip) is the preferred delivery system for lake musky, allowing the sink tip to hold depth while the fly kicks side to side on each pull.
• When to dial back retrieve aggression and employ a stutter-strip or extended pause with the Swine Junior, particularly during cold-water conditions when bass are holding and waiting.
• Why sharing newly discovered synthetic fly tying materials openly — rather than hoarding them — is essential to keeping those materials in production and available to the broader tying community.

Techniques & Gear Covered

The Optimus Swine is designed around a jerk-strip retrieve that drives its foam-induced side-to-side action, and Eli breaks down exactly how to execute it — stripping two feet with the line hand in alternating pulls, roughly like ripping a bag open. For lake musky, he runs a 10-weight with a 350–450 grain sinking tip, paired with a short 3–4 foot leader from loop to fly — a butt section of 40-pound to wire, finished with cross-lock snaps for fast fly changes. River smallmouth and striper applications drop to a 7- or 8-weight with a 200–350 grain tip depending on conditions. Construction-specific details are substantial: Mustad 32608 spinner bait hook (6/0 for the original), Rainy's Mini Me medium foam popper head reversed and goop-set with silicone adhesive, synthetic yak hair blended with flash for the tail, grizzly saddle feathers as flanks, Magnum Flashabou, everyday bucktail applied in top-and-bottom sections, laser dub for the head, and 1/2-inch eyes pressed and held in a two-touch goop cure process.
