Mike Schultz joins The Butcher Shop to deliver a comprehensive deep dive into the Swingin' D, one of predator fly fishing's most effective swim patterns for targeting smallmouth bass in Michigan rivers. This detailed conversation traces the pattern's evolution from its early 2000s origins through modern 2.0 variations, exploring the critical role of Larry Dahlberg's diver head design in creating the fly's signature side-to-side action. Mike shares the problem he was solving—creating a fly that would hang and move horizontally rather than just vertically like traditional leech and crayfish patterns. He walks through material selection spanning over 15 years of refinement, from the original beads-and-wire construction to today's shank-based articulated designs. The discussion covers tactical presentation details including optimal water temperatures (45-50°F+), rod and intermediate line selection, retrieve cadences and the importance of fishing at proper angles to achieve maximum action. Mike also provides updates on Schultz Outfitters' new e-commerce platform and upcoming events including the fourth annual Bobbin the Hood.

1. How to achieve unpredictable horizontal swim action by properly selecting and seating Rainy's diver heads, which create side-to-side darting movement that mimics wounded baitfish when fished at 45-degree angles on intermediate lines.
2. Why the Swingin' D fills a critical gap in predator fly boxes by suspending in the strike zone and allowing precise depth control through strategic weighting with lead wraps or tungsten scud bodies balanced against the buoyant foam head.
3. When to fish the Swingin' D most effectively—peak performance occurs in 45-50°F+ water during late March through May when smallmouth are aggressive and feeding in shallow 2-4 foot zones.
4. How to construct durable 2.0 versions using The Chocklett Factory shanks, Senyo micro shank connections, Ahrex XO 774 rear hooks and Gamakatsu 2/0 worm hooks up front to prevent hook failures and maximize hookups.
5. Why proper head selection and orientation matters—wider heads with substantial collars produce aggressive side-to-side action for cold water while narrower heads swim tighter for warmer conditions.

Mike emphasizes the Swingin' D's effectiveness stems from proper presentation on intermediate lines using 7-8 weight rods like the G. Loomis IMX Pro V2 or his signature NRX+ Swim Fly. The fly excels when fished at 45-degree angles from a moving boat, using erratic strip-and-pause retrieves that allow the Dahlberg diver head to create horizontal darting action. Keeling techniques using .020-.030 lead wire or Hareline tungsten scud bodies balance the buoyant foam head to achieve desired depth penetration. Mike details construction using articulated shanks (The Chocklett Factory, Senyo micro shanks), Ahrex XO 774 universal curve rear hooks and Gamakatsu 2/0 worm hooks up front, incorporating materials like Senyo's Predator Wrap, Whiting hen saddles, mallard flank and Blane Chocklett's rattle boxes. Leaders run 4-7 feet terminating in 15-16lb fluorocarbon tied with loop knots to the fly with no swivels. The pattern's versatility allows customization through flash colors, head widths and weight placement to match conditions ranging from high spring flows to lower summer levels.
