Deceiver Blue Grizzly although primarily used for saltwater species like Bonefish, Permit pattern imitates Baitfish in a variety of colors and has grown in populartity with many fresh water fly fishermen for Salmon, Trout, Bull trout and Bass.
Today I used this fly to catch Skipjacks on the Florida flats. Just like Baby Tarpon, and they hit this fly like a truck. It's also worked for Snook and Spanish Mackerel. They all seem to love it.
