Fulling Mill Tungsten Czech Pheasant Tail Black - Barbless

The same fly with the flash taken out

The same deep-water shape as the copper version with the flash taken out of it. There are days, usually bright ones over low clear water, when a warm metallic glint is the reason a fish turns away rather than the reason it commits, and on those days a dark slim nymph with nothing shouting about it is the better bet. Everything else is identical, so carry the pair and let the light and the water decide which one goes on.
