The Brassie has been around awhile and a great midge/chrionomid pattern. It will sink like a rock with the wire body, and if you use the bead head, even more so. Adjust the wire and bead size to the hook size. The wire body provides the segmentation. It is a similar style body to the Copper John nymph pattern. This midge pattern could be ties with out the bead. The peacock herl thorax fill in where the bead was with  more pronounced thread head. The bead head is tied off behind the bead, where as, with the non-beaded pattern the fly would be finished off at the eye….the more traditional end point.
