FishnDave a small clouser has been my top producer for crappies for a while now. But the colors I've been using are white craft fur for the bottom but blue hair of unknown pedigree for the top. The perch came on float & fly rig with a hare's ear fished as a dropper behind a larger clouser. The perch took the hare's ear.
As for the stocker rainbows I've only caught one on a charturse & white micro jig fished below a strike indicator. Me and a couple of fly fishing buddies plan on giving it another try on Sunday.
