Thanks fellas!
I do want to tie up some of the Clouser Swimming Nymphs, too. I usually swim nymphs for carp, rather than drag them along the bottom. But a lot of what I read leads me to believe these usually work best on the bottom, dragged. Maybe its just that I can detect the strikes better if the fly is moving...it helps me keep slack out of my line at least.
About the "pom poms"... My kids have a bag of these in different sizes/colors for making whatever it is kids like to make with these things (my son just usually glues big doll eyes on them). From the larger of these fluff balls, I've pulled small clumps of strands to use for tail materials on bluegill foam poppers.
I haven't fished with just the pom poms on a hook. Do they float, or do they eventually sink? That might work either way...
I'm wondering if the "Rainy's Bread Crumb Fly" might be made from Fuzzy Foam? I don't have brown, but not white. Maybe I could overlay the brown on something white...like those pom poms, maybe. But really, I don't think the brown is all that important, except to the fishermen.
