The colors dye lots are fairly consistent..but, the feather length varies greatly….I don’t use these for tying flies, rather, I use them for steelhead jigs…if the feathers are longer, 4â€Â+, the overall quality is better..when they’re on the short side, there seem to be more feathers whose barbels clumped and twisted…better to buy 6-8 packages of the colors you want, pick out the best, and return the others for a refund…tying with substandard feathers is unnecessary…
