Well we don't have a lot of grayling in Ohio... I can tell you that the brownies seem fond of it. I fish this the same way you'd fish a scud pattern and under the same circumstances - the difference is I'm imitating a sowbug so I'm fishing it on the edges of slow pool collections of rotting vegetation instead of the edges of weed beds.

FWIW, its a remarkably good bluegill and longear sunfish fly (they eat a lot of sowbugs on flowing water here) and has hooked more than a couple big carp for me.

I think the fish would rather have the Chadwick's. In an informal poll I found that I was only tempting fish that had a gross income under $100K per year which, as you know, is 92% of the population but only 3% of the fat population...
