Chuck Kraft has been guiding and fishing in Virginia for 45 years. He was the original fly fishing guide on the New River, James River, and Shenandoah River. He has been creating hard working, tough, simple, yet effective flies for decades. We owe a lot to Chuck for this pattern. We have boated largemouth to 10 pounds and smallmouth over 4 pounds on this fly. Carp and even musky love this pattern. We guarantee if you are fishing a river or lake that contains crayfish.....this fly WILL work in the appropriate size and color. Great on trout in our local spring creeks as well as out west. We honestly can't say enough about this pattern. If you don't believe us, take a look into our fly boxes, we carry over 100 on our boats! Currently available in Size #2 and #6 in Tan, Olive, Gold, Brown, and Black.
