A strong, braided or monofilament cord used in angling, designed to withstand a breaking force of 50 pounds, forms a critical link between the angler and the fish. For example, when targeting larger species in environments with heavy cover, a line with this tensile strength provides the necessary reliability.
The advantage of utilizing a cord capable of withstanding significant pressure resides in its ability to handle larger fish, resist abrasion against underwater structures, and provide increased confidence during retrieval. Historically, increased tensile strength meant sacrificing line diameter and casting distance, but advancements in materials science have minimized these tradeoffs.
