Rick,
When I used to fish the tribs in WI, egg-sucking leech patterns often worked really good. And double-fly rigs worked better than single flies. Sometimes I was too lazy to re-tie on 2 if my line broke, though, and still caught some fish. The theory was the first fly would get the fish's attention, and then they'd strike at the next one that came along.
Purple-bodied egg-sucking leeches worked best some days, olive bodies worked best other days. Some days a bright lime-green fly got their attention...sometimes a plain muddler minnow with a flash of gold or silver.
I never tried it, but I would suppose a bright "flesh fly" might work.
