The Copper Bead Head Pheasant Tail is yet another variation on the ubiquitous P.T. There are a few minor changes in the tying sequence when using the bead as well as adding the flash wingcase. Follow through this pattern for tips on tying it with or without the bead or the flashback. I like to use the bead head version as a dropper under a dry or in a combo with an unweighted nymph. The addition of the flashback makes this fly show up well off-colour water as well. There are a bunch of different variations possible, and they all work. It's up to you to find out which ones you like best!
