A great imitation for a Slate Drake (Iso) Emerger and a good late season fly for those picky fishing during the summer month. Fish it by itself or you can a PT Nymph behind it as a dropper and hit likely spots where you know fish are stilling. A good technique for when things are kinda slow on the water. All Sales on flies are final. No Returns or Exchanges. Sold in Half dozen or Dozen.
