Achievements in genetic dry fly hackle have created a consequential loss of quality tailing material.  Whiting Coq-de-Leon Tailing Packs are the perfect solution.  The long, stiff, glossy, and resilient qualities of the fibers on these Whiting CDL Tailing Packs produce perfect dry fly tails and are also very popular for European style nymphs.  The subtle speckled fibers produce tails that are as beautiful as they are functional and give your flies the look and presentation of the perfect dry fly or Euro nymph.
