You can't fish for bonefish or permit without thinking about crabs and shrimp. Both of these fish work the flats eating crustaceans as they move along. Successful anglers start with the right size and color fly (Some very serious anglers carry permanent markers with them to color the fly to match a particular flat.). The fly also has to hit the water with a minimum of commotion but still sink quickly. To minimize fouling SSFlies uses 20lb single post weed guard positioned to shed and deflect as much debris as possible while minimizing interference with hook-ups.
