I had the opportunity to meet Rene and Bonnie Harrop in Last Chance Idaho. I believe they (especially Rene) are perhaps the most innovative and accomplished tiers anywhere. They and their son and daughter sell their premium flies at the Trouthunter shop and some shop near Silver Creek, I believe.
Rene has a new book out called "Learning From the Water" which is wonderful and has the most beautiful photos of his flies and how he designs them. It is one of the best books I have read.
