If you have the time look up the article "Namesake Flies" under Features then Bob Boese. The Black Boudreaux shown there is probably the greatest fly innovation of this young century. So far I can personally attest to it catching bass, bluegill, redear and green sunfish, catfish, gar (yes, two spotted gar), white and black crappie (sacaliat), rainbown and brown trout.
Got your attention yet?
