Maintaining a balance of power, sensitivity and environmental camouflage is the holy grail of fishing line qualities, and Gouken fluorocarbon fishing line from SPRO hits the mark on every point. Its small diameter allows exceptional sensitivity, helping anglers maintain contact and feeling with baits and lures. Although the diameter is small, the line delivers tough-as-nails abrasion resistance for anglers fishing over rocks, logs and weeds and its super tough design is effective for sticking fish with hard hook sets. Fluorocarbon enables the line to blend into the environment by allowing light to pass through rather than refract off of the material, an asset when targeting pressured or spooky fish. It’s a must-have option in just about every type of environment outside of muddy catfish holes. Strength ratings include 10, 12, 15, 16 and 20 pounds. Retail: $18.99/150-meter spool.
