Monofilament Vs. Copolymer Fishing Line

Monofilament Vs. Copolymer Fishing LineOne of the most difficult things any angler must do is determine what fishing line to use in what situations. For decades, the choice was not one of composition, but brand. Monofilament fishing line dominated the market for a long time, but copolymer fishing is now a popular choice. While it has properties very similar to a monofilament, copolymer resins offer some advantages and disadvantages. Often the choice may come down to the type of fishing the angler is doing.

Points of Comparison: Copolymer vs. Monofilament

Factors to consider when deciding between copolymer and monofilament fishing line include: 


In this particular case, the copolymer line is superior. This elasticity not only helps prevent the hook from being pulled out of the fish's mouth but also makes for easier and more accurate casting. At the same time, this will allow some fishing jigs to act more naturally in the water, which can be of a concern when working with lures in deeper water.



The copolymer fishing line also has an advantage here, which aids in casting. One of the problems with true monofilament lines is that they often retain their memory, which leads to problems when casting and retrieving the line. This memory keeps the line in loops, or wanting to go in loops, even when the desire is for it to be perfectly straight. Tangles and "bird's nests" can result from line that retains too much memory. Copolymer lines do not have this problem. 

Abrasion Resistance

Anglers often find themselves dealing with heavy brush, rocks and other objects both above and below the water's surface. With regular monofilament, such structures can cause nicks that eventually lead to the line breaking under less stress than it would normally. This can cost the angler a fish. Copolymer lines are more resistant to this type of damage, ultimately making the line more reliable.


This is one area where monofilament seems to have the advantage over a copolymer. The copolymer line is usually thicker, which leads to greater visibility in the water, as well as fewer yards on the reel. Some anglers feel line visibility can discourage a fish from striking, especially in clear water.


For those who are concerned about cost, monofilament and copolymer lines both offer a good value, especially compared with some of the other fishing line technologies on the market. Still, the best value is monofilament lines. In some cases, it may be possible to find a discounted copolymer line for the same price as a high-end monofilament line.

Selecting the Best Fishing Line 

In addition to these two types, you may also want to consider the advantages of braided or fluorocarbon fishing line. Do a thorough comparison between the various options before making your decision. Ultimately, you should select the type of line you are the most comfortable using. You may even want to alternate between multiple types based on the type of fishing you are doing at any given time. No matter which type of line you select, it's important to use it properly. Make sure you know how to set up, replace, test, and wind a fishing line. It's also important to properly store fishing line
