There is a reason some fly patterns are well known. Putting them on a jighead can make them even better.

Been doing this with trout for years, and I'm not going to stop now.

Anything that you can do on a nymph hook, you can do on a micro jig hook. I use #10 and #12 1/80 and 1/100 oz jig hooks a lot for trout and creek fishing bluegills. 1/64 oz works well too. Bluegill don't mind a fairly big nymph.
