This is the grandfather of bonefish flies and of all the designs that ride hook up with a wing covering the hook point. Chances are, if your guide asks what you have tied on and it's not a Charlie, he'll bite it off and tie on a Charlie or some form thereof. Don't go bonefishing without a box of Charlies. In white, yellow, tan, pink. Flies available in sizes: 4, 6, 8.Shallow: Plastic bead eyes, slowest sink rate.Tailing: Metal bead chain eyes, medium sink rate.Deep: Non toxic metal dumbbell eyes, fast sink rate.
