I have, in 35 years of flyfishing, managed to catch ONE fish on a Quigley cripple during a PMD hatch. Admittedly, it was a heck of a fish, and a pic of it with the fly taped to it sold the local shop a thousand flies that summer, but I never did manage to catch another fish on it.

Interesting to see how different our standard patterns are, and that they all work, and that we all swear by them, even though no two of us tie the same ones. *S*
