This fly holds a special place in my fly box. It was the first streamer I ever caught fish on and I continue to use them often. Depending on color they can represent a baitfish or a leech. They will catch everything from Bass to Trout. We tie ours with a conehead and lead for weight so you can fish them on floating lines. Stripping them works great, but probably the best way to fish them is dead-drifting one under a big indicator. The smaller sizes work well for point flies on a Euro Nymphing Rig.
