... fish in the eastern part of the country.

But I'm with DUB when it comes to the Intermountain West. I very seldom, if ever, put flash on a fly of any kind. I do use some gold, copper, and silver wire ribbing, and I tie some "coppery johns" which don't have a wing case or epoxy, and a beadhead occasionally represents a form of "flash" but beyond that I prefer simpler flies.

I know some excellent fly tiers and fishermen from SE Idaho and Western Montana who are dedicated to flash. That's cool. Works for them. And then when my flies come along, the fishies see something different.
