A different concept in weighting flies. Strips of lead that we extrude with a channel or grove in it. To make any fly ride upside down "point up" simple lay a strip on the top of the hook shank and secure it with a few wraps of thread. If you want the fly to ride with the hook point down simply tie the channel lead on the underneath side of the hook shank. An alternative to expensive scud weights with more sink per inch!
