The Simple Crab fly is a deadly flats fly for bonefish and permit. Instead of a super heavy crab fly that will spook bones the Simple Crab lands softly and if you fish it slow bonefish can't resist. Spooky permit in the Caribbean love this fly as well and you are able to present it with stealth so much easier than many of the heavier crab patterns. This is a "don't leave home without" saltwater flats crab fly.
