Burkus Riffle Robber Primrose

"Riffle Robbers are a unique PMD fly with a tubular trailing shuck opposed to loose fibers. With a CdC wing and color variations, it has proven its effectiveness on some of the most fabled technical rivers in the West: Silver Creek, Railroad Ranch of Henry’s Fork, and Missouri. It has high marks for tricking some of the most wary PMD sippers." - Ken Burkholder
