Things We Like and Dislike about Monofilament

The Good Stuff

Affordable

It comes as no surprise that monofilament lines are so popular when they cost the least out of all fishing lines. Not every angler out there can afford a braided line. Beginners also don’t want to push their budget, so an affordable monofilament line sounds the most reasonable.

Easy to Use

Another factor that makes beginners love monofilament lines is their simplicity. Monofilament lines are the most manageable, thanks to their stretchiness. Also, it’s a piece of cake to cut, tie strong knots, or rig with a monofilament line.

Buoyant

Monofilament has a low density compared to water, so it floats. Its floatability makes monofilament ideal for surface water lures, or whenever you don’t want a line that sinks too fast.

Diverse Color Options

Thanks to nylon being the easiest to dye, monofilament lines come in a variety of colors. Colors dramatically affect your fishing, whether in using high-viz colors to help you monitor your line or low-viz colors to hide your line from the fish.

Shock Absorber

Monofilament’s stretchiness gives it an advantage, which is good shock absorption. 

Good shock absorption means you won’t struggle violently with a fish in a sudden hookset or when a fish attacks you. The line goes back to its original form as if nothing happened.

Thicker Diameter

Monofilament lines have thicker diameters than their fluorocarbon and braided counterparts. This quality gives these lines excellent abrasion resistance. A quality like this is to-die-for, especially if you’ll fish in an area where there are rocks, weeds, or any sharp edges.

The Bad Stuff

Stretch

Monofilament’s stretchiness is cool until you realize that it reduces the line’s sensitivity to bites, movements, or any sudden changes you need to be aware of immediately. This lack of awareness can lead you to lose fish because you don’t react soon enough.

Deterioration

Monofilament is a line that you’ll have to change very often. It deteriorates due to exposure to UV rays. Also, it changes properties when it’s wet. It is the most affordable, so it would probably hurt the least to change it when it weakens.

Buoyant

If you’re planning on deep-sea fishing and deep casts, monofilament won’t work for you because of its buoyant nature.

What to Look for When Buying a Monofilament Line

1. Color

One of the best aspects of monofilament lines is the variety of colors. However, sometimes being offered multiple options can be confusing.

The options provided are mostly clear, low-viz colors, and high-viz. Clear and low-viz colors are for invisibility, while high-viz colors are to be seen.

Clear lines are perfect for clear water, but it has to be cleaned regularly, so it doesn’t turn white. Blue is also perfect for clear water. Low-viz colors such as moss green work great in camouflaging your line in bodies of water packed with weeds and structures.

High-viz colors such as bright yellow or lime green help anglers see the line and keep track.

2. Abrasion Resistance

A line with high abrasion resistance is needed if you’re fishing in a place with a lot of structure, rocks, weeds, or sharp edges. You want a line that is as tough as the environment you’ll use it in.

However, not all kinds of fishing require high abrasion resistance. If you’re fishing in a hassle-free environment or using a topwater lure, you can do without abrasion resistance.  

3. Line Strength

The ability of a line to carry a certain amount of weight before it snaps is called a pound test. A line’s pound test should match your target fish’s weight in pounds. If your target is 10-pound fish, then you should get a 10-pound line. 

It shouldn’t be less than your target fish’s weight, or it will break. However, you shouldn’t go too heavy with the line either, unless you know you can handle it.

4. Memory

Memory is the line’s ability to retain its last shape that it was in for a while. This tendency leads to curling and tangling; nobody wants to deal with that.

So, you should be on the lookout for low-memory lines because they stay straight off the spool. A low-memory line is what you need for a smooth and long cast.

Frequently Asked Questions:

What Are the Benefits of Monofilament?

For starters, monofilament is the most affordable fishing. In addition, it is the easiest to use or tie knots with. Also, its thick diameter and stretch make it tough against sudden attacks, structures, and rough surfaces. Finally, the diversity in color options is insane.

Which Is Better: Mono or Fluorocarbon?

Both have their pros and cons; the choice depends on your needs. Monofilament is stretchy, tough, buoyant, and easy to use. Fluorocarbon is practically invisible, sensitive to bites, waterproof, and long-lasting.

Nonetheless, monofilament deteriorates fast and has low sensitivity to bites and movements. Fluorocarbon is more expensive, has higher memory, and sinks too fast for some situations.

How Long Does a Monofilament Line Last?

It is said that you should change it once a year, but the answer depends on how often you use it, store it wet, or expose it to UV rays. As a rule of thumb, you should always check your line for any signs of wearing out.

What Type of Plastic Is a Monofilament Fishing Line?

It is made of a single fiber of nylon. Thanks to its high melting point and impressive abrasion resistance, it only made sense to use it to make these handy fishing lines.

If a monofilament line isn’t made of nylon, it’s probably made of fluoropolymer for extra durability, which is a fluorocarbon-based polymer.

Final Thoughts

Finding the right monofilament line for you is not easy, but we hope our little research has helped you. Now, let’s go over some highlights.

For a large variety of colors for different purposes, consider the KastKing World’s Premium Line and the Berkley Trilene Big Game.

If what you want is a tough monofilament that can handle the most aggressive fish and the most unfriendly environment, check out the SpiderWire Ultracast and the KastKing DuraBlend.
