To be perfectly honest, Paul has also pointed out that he feels this year's weather pattern (temperatures, amount of sun, etc.) and perhaps a bumper stocking program might also have been reasons for the fabulous fall fishing.
Paul and I talk frequently by phone, and when he described the fly he was constantly (consistently?) catching fish with I recalled the article he wrote for this Web site on his Chronomid patterns. I thought the fly he had described was #2 in the article, and Paul confirmed by email yesterday that that fly (posted again here) was indeed the one he's been using. As he stated in his email:
This loop-wing adult Chironomid pattern is nothing more than the already famous Griffith's Gnat tied shorter on the front half of the hook with a loop of gray polypropylene yarn to represent the wing, and to add floatation and visibilty to the fly as it sits on the water. This fly is most effective when fished with little or no imparted motion. If the fish are actively feeding on adult chironomids, they will eventually find your fly.Paul likes it in a size 16, and Jim fishes both 14 and 16.
