Consider this flytying material, developed by Henry Hoffman, for your tails and wings and bodies on stillwater patterns. Marabou is a great material, but if you have an opportunity to use this material you will relegate marabou to a lesser roll. Hoffman spent years developing quality hackle for the perfect dry fly. Later, he turned his efforts toward a fluffier feather, Chickabou. That often discarded lower portion of the feather peeled off and discarded is a wonderful material. It works great for bushy tails, pulsing wings and when wound around the shank a buggy look equal to marabou or ostrich. I am not advocating abandoning ostrich or marabou…just find and include Chickabou into your patterns like the Kaufmann Dragon or Timberline Emerger or Mini-Buggers or any stillwater damsel, dragon or nymph.
