The Straggle Bach Aqua Barbless Size 12 is a superb, modern Diawl Bach variation developed as a searching stillwater nymph. It retains the slim, suggestive form of the Welsh original but adds an aqua holographic butt and mobile straggle collar, giving extra flash and movement without the bulk of a lure.
Fish it on a floating line as part of a nymph team, either on a dropper or point position according to the weight of the other flies. A slow figure-of-eight, steady drift in the wind or short draw-and-pause retrieve all suit the pattern. It is useful when trout are feeding on small nymphs but need a clearer trigger. Its balanced profile gives it the appeal to turn interest into a solid take.
