Avalon Permit Fly
In preparation for Cuba, everywhere you look you will hear about "The Avalon Fly". You absolutely need to have this fly for Permit. This is the official pattern, not a knock-off or imitation, that is tied in Cuba. If you are traveling that far and spending a small fortune to get there don't settle for anything less. The Avalaon fly rides evenly thanks to the beads along the bottom that aren't just for attraction, but keep the fly balanced and not taking nose dives and acting suspiciously.
