The balance and performance of a quality dry fly is optimized by a resilient and glossy tailing fiber to mimic the natural. Synthetic materials are too stiff, puncturing the water surface and sinking a dry fly faster. The naturally stiff yet supple characteristics of the Coq de Leon humoral tract feathers have been the tailing material of choice for centuries. Whiting Farms offers these tailing feathers in convenient packs. Color choices include light, medium & dark Pardo. A variety of dyed colors are also available.
