HVK Leadhead Peeping Caddis Collection Designed by Hans Van Klinken. This is a deadly cased caddis or sedge pattern for Grayling and Trout. Tied on a Daiichi 17101 hook to Hans specifications. We have fished with Hans many times and we took him to the Nidd in North Yorkshire to a river he had not fished before. The experienced anglers there caught between 1 and 4 fish. Hans was there for the first time and was fishing with these Leadhead Peeping Caddis flies. He caught 16! Each batch is quality checked by Hans personally before we start selling these flies.
