Roza's Olive Nymph

A great Baetis nymph imitation, this fly is best used when the water is clear and the angling pressure is high.  

From the designer, Lubos Roza: "A special type of fly for trout and grayling in extremely clear water. The fly contains no flash or bight colours and is most effective at catching in clear water that has been heavily pressured by other anglers."
