For most angling situations, monofilament or braided line works fine. But there are plenty of scenarios where fluorocarbon works better. The material’s low visibility, abrasion resistance, high density, and stiffness make it the logical choice for light-tackle finesse fishing, such as chasing winter seatrout, or when nymphing for selective rainbows and browns in clear spring creeks. The demands of fishing around saltwater pilings, oyster beds, wrecks, or other structure make fluorocarbon well suited to clear nearshore environments. Here are a few other variables to consider before you drop your dough on fluoro.
