I dunno. I probably catch more fish on a per-year basis on an olive bugger than on anything else, on the order of a thousand or more trout. Then again, I catch that many on a glo bug as well. And could, if I so desired, probably do that on a foam hopper. The hopper would be more fun, I think, but I would have to give up fishing about seven months out of the year.

Oh, wait, I don't HAVE to limit myself to one fly, so I won't.
