Sandfly, I agree with you. However, I eliminate the palmer hackle. As you know, the stimulator was designed for the "salmon fly" hatch out west, which is a large adult stone fly. I never saw the need to add the palmer hackle when fishing it in PA waters. Therefore I call mine a semi-stimulator. Can be used as an attractor, a searching pattern, an adult large stone fly, or when tied with a dull orange body it is an effective pattern for the October Caddis.
