Vigs Cock Robin Influenced by the salmon fly I tied this specifically for Grand Lake Stream, which is a very productive fishery in the fall and in October specifically. GLS is located in Eastern Maine and is one of the most well know, fished and productive salmon rivers that this state has to offer. The fly is a great fall pattern and the salmon absolutely hammer it. Mustad 94720 Hook  $5.50 Select Sizes Size 2Size 4Size 6 Martinek Hook Display Fly  $25.00
