This may be one of the most deadly flies for big fish ever created. The sex dungeon is a jointed fly that contains a bit of everything.....lead eyes, deer hair/sculpin type head, ****** type hackle, marabou and some rubber legs. Deadly on big trout.
The fly was first tied last year by a guy called Kelly Galloup and is tied in three main colours black, olive and brown as shown here.
The main/front hook is tyed on a size 2. And asyou can see is popular for the browns.
Maybe too big for over here but this fly is getting very popular State sided!
