You already mentioned it Joe. A Woolly Bugger!! A Woolly Bugger can imitate many different species of trout prey. Anything from leeches, hellgrammites, crayfish, minnows, tadpoles, Madtom catfish, or large stone flies. It’s a pretty fail safe fly to start with. Tie it in several colors and sizes, weighted and unweighted and you will have all the variations covered. It will catch fish when other things won’t. That’s my 2 cents, but there are many experienced tiers and fishermen on here that will help you. Good luck and have fun with it.
I can’t think of a better all around trout fly in different sizes. My only suggestion is try tying some on 1/80 oz jig heads. I think you’ll be pleased with the results in still water or fished on the swing.
Woolly buggers are great! I also recommend the Pheasant tail nymphs which are relatively easy to tie. A Jared ear nymph would be good too. The simplest thing I can think of is a peacock nymph. Good luck!
