The Kingfisher Butcher is a great trout fly when fished on the point of a team of wets. I use it in sizes 14 and 12 in a light breeze, but in a higher wave a size 10 is better. I feel confident fishing it for rainbows or Browns in reservoirs or Scottish lochs, and I am told that it is an excellent sea trout fly and has the reputation of tempting the larger fish at night.
