Those are some good tips. We fish tourneys year round on current river and winter fishing can be very slow, but also very rewarding. As far as tube color your best bet is to match the crayfish, the smallmouth's primary food source. One reason I believe a natural presentation is vital in the winter is water clarity. If you think your favorite stream or river is clear in the summer it is nothing compared to the gin colored water of the winter. Even now the cool nights we are having are beginning to clear the streams and rivers. With better water clarity comes more easily spooked fish, so stay as far away as you can cast. Where you might get away with a lo-vis green 10# in the spring and summer, it would be better to throw a lo-vis green 8 or 6# in winter. One thing a lot of guys don't know about (and I shouldn't give away the secret) is a crankbait for smallies in the winter. Any slight rise from rain will slightly dirty the river and the fish will go nuts over the right color 200 or 300 series bandit or wiggle wart. As far as black river in southeast missouri goes, the winter is by far the best time to fish. I will put my five biggest smallmouth or Kentucky's I catch in Black River in the dead of winter against any a guy could catch in the spring or summer from the same waters. The fish may be slow, but they are still feeding. Slow down your presentation and you will find that you've been sitting in front of the fire wasting your winter weekends away when you should have been catching the best bass of the year. It seems the keeper to dink ratio is a lot better in the winter as well. Don't forget about the walleye and chain pickerel. They love to feed all winter and the cold water makes them more tasty! (throw back them smallies so they can grow bigger though)
