I tie another with globug yarn in white or pale pink with mustard back and a thin red streak in each section, 4-5 sections each with my wood-duck creeper legs and a collar. I used to call it my "bait" fly. Looks very much like a real sand shrimp.
Worked very well as a dredging fly. Doublespey has adopted it and might have some variations of my original theme to offer as well.
