A friend who owned a hardware store years ago in our town had a big bass mounted. He caught this bass on a Creme Scoundrel 6" plastic worm, air temp was 35 degrees, and spitting snow. It used to be common in my area for guys to stop fishing plastic worms in later fall, and switch to jigs , or stop bass fishing for the year. Since a plastic worm is my favorite bass lure, I fish them through the cold season too. Jigs can be excellent too, as many know. I opt for a Zoom finesse worm, Texas rigged. It seems like darker colors have worked better in cold water, and of course a very slow retrieve, sometimes letting the bait sit for several seconds before dragging or slowly lifting from the bottom. Weeds are not usually much of a problem in cold water, but I still go with a Texas rig the most. Sometimes a lighter split shot rig can work well too. Fishing slowly is the key. For me, I'm sure it's 90% a confidence thing, as I've caught more bass through the years on plastic worms, of various sizes and brands than any other baits. They will definitely produce in colder water. Any others fish them in cold water, or do you go with something else? If so what's your favorite worm/rig?
