The Casual Dress nymph developed by "Polly Rosborough" is one of the few nymphs which I believe effectively mimics natural mayflies, stoneflies and caddisflies. This lets us fish it successfully in all types of water at all angles. I use it in sizes 8, 10 and 12 for trout on the stocked trout streams and I have used the size 8 as a dropper below a popper on the smallmouth bass rivers.
