Monofilament fishing line have many advantages that make a popular choice for most fishermen. Mono is easy to handle, is relatively inexpensive, and has stretch which will help absorb some of the shock when a big fish take a bite and start pulling on your tackle.
When you're fishing for sharks, kingfish, bluefish and other toothy denizens of the deep, a wire leader is a must. Wire fishing leaders will prevent these fish from biting through your line with their razor-sharp teeth. That will help you bring them in to shore or your boat while also saving your baits and lures.
Fluorocarbon has several benefits over mono – it's more abrasion-resistant, and it has less stretch – but the main reason most fishermen choose fluorocarbon is because it's less visible to line-shy fish. ... That's exactly the motivation behind Seaguar's new Gold Label fluorocarbon.
