OPST's Intruder shanks are designed for tying flies with dumbbell eyes. The returned eye creates a platform for the dumbbell, lead, tungsten eyes to lie securely, increasing stability and preventing the annoyance of spinning and insecure eyes.
OPST micro shanks are similar to their standard shanks, but with a thinner diameter intended for intruders where a lighter fly is required. Their lighter weight also makes them ideal for surface wake flies for sea trout or salmon.
OPST has found a supple, durable and highly fishable intruder wire for all of your trailing hook flies. OPST wire is the ideal diameter- thin enough to fit through hook eyes with ease but with enough body to secure tightly with thread. In blue and red, per 1 meter.
