Movement is enticing to trophy trout (and we don't mean dinky trophies) Nearly identical to the famous Sex Dungeon (the name hurts the search results..) This fly has articulated hooks. The front is a b10s stinger hook, the rear is a Daiichi 2220 streamer hook. The articulation allows us to use smaller hooks to prevent harming the fish It also allows for longer, larger patterns without extra bulk or weight. Maximum size, minimum materials and weight. The perfect big-fish streamer.
