I have not heard how South or North Twin are, but both should be really picked up as Fall returns. Balanced Leehces and Chironomids, Dasmsels and Blobs are fall patterns to use. These are great places that fit short sessions as the daylight lessons, and they are less exposed to bad weather, and easy to get in and out from, and are perfect size to use a kayak, tube or pontoon boat, or launch a drift boat to row around and they both usually fish well into November pending some normal fall conditions and no weird really harsh arctic fronts. Good places for a lot of us to finish the season before things get too cold in about a month.
