Several years ago I wrote an article on Winter Trout Fishing with the best flies and techniques to use. This assortment contains most of the flies listed in the article along with a few that we have had success and added to the fly shop line recently. Assortment comes in 10 compartment fly box with 11 flies (labeled). Pearl Marauder size 10 Black Marauder size 10 Mr. Rapidan Parachute Dry size 18 Mr. Rapidan Soft Hackle, Olive size 16 Mr. Rapidan Midge Dry, size 20 Copper John Nymph, Zebra size 18 Perdigon Nymph, French size 16 Perdigon Nymph, Olive size 16 Murray's Dark Stonefly Nymph size 14 Murray's Little Black Stonefly Dry size 18 Olsen's Barbless, Peacock Nymph size 16 I recommend a Trout Nymphing 6X leader for the nymphs and a Classic 9ft 6X Leader for the dry flies.
