These patterns have been tested over the last two years by myself and others in various rivers on the Western Slope and Front Range in Colorado. They have also been fished in California and Idaho with good results.
I tie these in a variety of colors and they have all had some success. The Tan, Brown and Chartreuse colors have produced the best results.
Send me an email if you would like the recipes and tying instructions.
Tie some up and let me know how they worked for you!
