Have you ever tried fly fishing for carp? They grow to over 20lb and are great fun on a reservoir rod. Better still they take well during the hottest months of July and August when the Rainbows don't want to know. Just throw out some chum mixer and the carp will wallow on the surface. Cast one of these flies amongst them and you're in.
Two selections of 5 floating deer hair patterns to represent biscuits & bread for surface fishing for carp.
