verything about modern flyfishing is fast. We’ve got fast rods, fast-shooting heads, fast-drying UV resin, and even premade wings, legs, and tails that let you whip up flies faster than ever. This might be why spun-hair bass bugs aren’t commonplace in fly boxes today. Everything about them is slow. They need to be fished with patience, you can’t knock them out at the vise, and their air-resistant bodies made Granddad’s slow, noodly fiberglass rod the perfect hair-bug delivery tool. Thing is, spun-hair bugs haven’t lost an ounce of potency since Granddad’s day. And while it’s true that a well-made hair bug isn’t cheap, if you know what to do with one, it’ll repay you with more giant fish.
