Upavon Copper Flash Damsel Straggle Hackle takes the foundation of the Blue Flash Damsel — one of the most proven stillwater and streamer color combinations in the range — and replaces the blue flash with warm copper metallic fibers for a subtler, more naturalistic profile that reads differently in clear water and bright conditions. Use it for damsel nymph bodies and streamer collars where the copper flash adds iridescence without the hard blue signal, as a thorax wrap on larger nymphs, or palmered as a collar on wet flies and lure patterns where the copper-olive combination suggests life without triggering refusals from selective fish.
