Barbless Biscuit Fab - The biscuit fab fly is hugely popular. Its subtle colour, make the wariest of trout, less wary. An excellent fish catcher when trout are cruising, feeding on daphnia. One of the best colour options when using the washing line technique with nymphs. Its foamed tail end, allows it to sit tantalisingly in the water, sinking slowly when suspending other flies. Tied on the Fasna F500 hook range.
