What many smallmouth anglers fail to understand is that monofilaments and copolymers are not a thing of the past. They are just as applicable today as they were in their infancy during the 1950′s and 60′s. I use these lines, mostly copolymer, ranging from 6 to 10 lb test about 80% of the time for clear water bass. However, if braided superlines are indeed used for smallmouths (yes, I use them a lot myself also), I use nothing greater than 20 lb size, which in comparison is about 6 lb diameter in monofilament. Lighter line whether it’s a clear monofilament and copolymer, and 100% fluorocarbon or hybrid-fluoro is the best way to go about business when dealing with clear water and its high visibility.
