As the names imply, monofilament is made from a process using a single strand and copolymer uses two strands. Copolymer lines were developed to resist abrasion and increased knot strength and promote thin diameters and low memory. Their strongest features according to some are low stretch and higher sensitivity.

Monofilaments have ruled the roost for decades and continues to be the number one selling type of line all over the world due to it’s selection, performance and pricing. Monofilament fishing lines are used in a plethora of techniques and have a super wide range of strengths available starting at 1 lb test and reaching up to and over 100 lb test. Subtle differences between brands often include abrasion resistance, manageability and memory. Several manufacturers offer multiple versions of their product, each offering different characteristics… some like Berkley Trilene offer a Extra Tough version (XT), Extra Limp (XL), and Big Game (Impact Strength) just to name a few.
