Our Tough Trace is ideal for pretty much any saltwater fishing environment or method, but it comes into own when you're fishing around any sort of structure. The high level of abrasion resistance means it can tolerate coming into contact with rocks, markers, or any underwater structure, as well as chafing in the fish's mouth during long battles. It can handle the shock loads from big hits from species like kingfish and tuna, because it has more stretch than fluorocarbon. It's also more supple, which can help your lures, bait or soft baits swim more naturally.
