I was fishing in YNP last year and came upon, what turned out to be, a nice cutt-bow feeding under an overhanging willow. I tried 5 different flies before I even got any interest, then had to change size 2 more times before it took. That was about the best 30 minutes fishing I've had in a long time, a heck of a lot more fun than if I tossed the "One" fly and hooked it right away.
About the most I can tie of any one fly at a sitting before I need to change things up is 2 dozen, so "No". Anyway, what would I do with all the stuff I have now?
Regards,
Scott
