The Squidro Blue is one of the best all around color combinations. It is a tied like a classic intruder pattern but utilizes tipped dyed rubber legs instead of ostrich which allows it to sink faster, swim better, and have even more movement in the water than a signature intruder. It is tied on a 35 mm Waddington Shank with a size 2 Gamakatsu Octopus trailing hook. The total fly size is about 3 ½ inches long. Size 2 only.
