This fly came out as a slight variation on the Iso Nymph. Where this fly shines is its buggy appearance and how easy it is to change the color and size without changing the design itself. I tie this fly for almost all of the major insect hatches but simply adjusting the color and size. I also tie it in a peacock color with an orange bead for off color water and steelhead. This fly puts more fish in the net for me and my clients than most other patterns throughout the year. By purchasing this product you agree to the Terms and Conditions as set forth by the seller.
