Hank's Quick Tips: Characteristics of Fluorocarbon Line
Fluorocarbon fishing line is an alternative to monofilament that more anglers are using. The latest of the new lines looks like mono but is made of an entirely different material. Fluorocarbon is said to refract light. Therefore, it is virtually invisible beneath the surface, making it a good choice for finesse fish in clear water.
Other benefits include toughness and sensitivity. The line has less stretch than mono but more than braid, offering a fair compromise. However, it tends to be a little stiffer than most monos, although manufacturers are doing a better job of making fluorocarbon lines more manageable.
Perhaps the most noticeable difference is it sinks, whereas mono and braid tend to lie on the surface better. The skin factor makes fluorocarbon ideal for fishing stick worms like Senkos because it allows these baits to flutter better on the fall. However, it's not a good choice for topwaters designed to "walk" or "spit" across the surface.
