Anglers must consider the amount of stretch in their fishing lines. This is important to their success rate at hooking fish. Some lines stretch more than others do, which can be a good thing or bad, depending on the angler's skill.
Braided lines, designed for great strength and composed of multiple-spun synthetic fibers, have barely any stretch to them. This means that when a fish bites the attached presentation, the angler will immediately feel the nibble, allowing her to set the hook. Fluorocarbon line has little stretch as well, making it sensitive to bites.
Monofilament fishing line has the most stretch of lines on the market. The Go Fishn website notes that this factor makes it more flexible for casting purposes. However, the stretch also makes it more difficult to distinguish bites and means that when you set the hook, the fish has a split-second to react and escape that it does not get from braided line.
Anglers who employ low-stretch fishing lines must adjust their tactics. If they typically use monofilaments that stretch and then change to braided line, for example, they may overreact to a bite and set the hook with too much force, pulling it right out of the fish's mouth.
