For fall, I like some generic nymphs, PT will do as well as caddis pupa and larvae. For dries my most common is an ISO emerger. Buggers can do great when fish are aggressive. I like white crystal bugger w/ blue hackle or gray ghost bugger (gray tail and hackle, bright orange body, gold oval tinsel rib)
Fall through winter I always have an egg pattern - small glo bug (16 to 20) or sucker spawn.
In winter more midges, baetis nymphs (juju baetis is a good one, pt is OK), and little black stoneflies. Zebra midges are great, but I fish limestoners a lot in winter and different colors make a difference some days. Little orange caddis are good where plenty of chimarra caddis are. Dries are small olives or midges - color to match stream.
Winter streamers tend more to white or black rabbit strip leech type flies that can be fished very slowly. Have had years when an olive over cream craft fur streamer with a dark lateral line was the ticket.
