Yep, trout and smallmouth with 1/32-1/16-1/8 oz brown black or olive, they are killers.
I tie trout specific jigs 1/64 down to 1/100 oz. and mimick my favorite nymph and scud patterns. They get down quick when fished under a float, or you can add lead wire to the hook for more wight before tieing the jig , and drift/jig them with no float.
Tie a few in drab colors and a few in bright colors, and you'll have the bases covered. Work good on panfish also.
