The Pros and Cons That Come with Monofilament Lines

1. Pros:

Shock Absorbance

Monofilament lines are mostly made out of nylon, which is pretty tough. It also has an excellent level of stretch, low memory, and a wide variety of different diameters. All these factors allow the lines to be quite sturdy. They have a high tolerance for the wear and tear that fishing regularly causes.

Manageability 

Monofilament line is your basic fishing tool. It is quite soft and flexible, plus it comes with an excellent variety of options that allow you to pick a line that’s perfectly suited for you, making it quite easy to handle.

Affordability 

Affordability is one particular merit of monofilament lines. Although you can find some of them extremely expensive, the majority are within anyone’s budget. Especially if you’re a beginner still trying your hand at some simple casts, you wouldn’t want to spend an arm and a leg on a line.

Floatation 

Monofilament lines tend to sink slowly, making them an ideal choice for topwater fishing. The reason behind that is the fact that nylon isn’t a dense material.

Resilience 

Monofilament lines can be made out of nylon, and they can be made out of other materials such as Dacron, polypropylene, fluorocarbon, or polyethylene. These other materials tend to be a little bit more expensive. Yet, they offer you extra strength, longer casts, and longer lifespan. 

Monofilament lines can take a lot of beating as they can be used with various fishing techniques, no sweat what-so-ever.

Exceptional Knotability

We have spoken about the manageability of monofilament lines; this factor leads to another advantage, which is superior knotability. You can efficiently perform various knots on this line with complete assurance that it will hold those knots perfectly.

Far Casts

With its superior abrasion resistance, floatation, and manageability, monofilament lines tend to be the chosen ones when anglers want to perform longer casts. They simply have a higher tolerance for the elements.

Visibility Spectrum

You’ll find that monofilament lines come in a wide variety of colors allowing you to choose whatever that will suit you and your fishing environment best.

2. Cons:

Susceptible to Elements

Although these lines are quite sturdy, continuous exposure to UV light rays and moisture without proper maintenance and cleaning would cause it to lose its shape and strength.

Stretch vs. Sensitivity

Striking a balance between just enough stretch to tire out your prey and adequate sensitivity to not lose your target before meeting it in the first place is quite hard. Some lines have too much stretch while others are too sensitive, but they will snap at the very early signs of a fight.

Water Absorbance

We have previously mentioned that continuous exposure to moisture might very well ruin your line; that is because monofilament lines stand to absorb a lot of water.

What to Look For When Buying a Monofilament Line

1. Line Diameter

The thinner your line is, the better, as it provides lower visibility and better manageability. Yet, don’t let a thinner line persuade you into agreeing to low strength. 

Always try to know a range for the fish sizes that you’re going to be chasing. Such knowledge will help you purchase a line with adequate weight test and thickness. 

2. Weight Test

This is the strength of your line and how heavy it can lift. The market offers a vast spectrum of weights, so you will definitely find something that will suit you. 

If you’re going for a cumbersome fish, then definitely aim for a higher weight test. However, if you are going after little trout, crappie, or panfish, then a lighter weight test will do just fine for you.

3. Abrasion Resistance

The lifespan of a well-kept monofilament line is around six months. Nevertheless, you must always keep in mind several variables that would affect the durability of your monofilament line. 

The most crucial factor will be what kind of water you’ll be fishing in. Saltwater will demand a much more robust and, therefore, more expensive line, while fresh or brackish water tends to be a little bit nicer towards fishing lines.

4. Visibility

You must always keep in mind the fact that the fish may very well spot your fishing line, and that will simply ruin your whole fishing trip. 

Try to go for clear lines or colors that can easily be camouflaged and blended into nature. These colors include dark greens, browns, and blues. They will still be visible to you. However, the fish will be none the wiser.

5. Stretch

Stretch is always a controversial element when it comes to fishing lines. You want your line to have enough stretch to give you the ability to fight and tire-out your catch, yet you don’t want too much stretch that can lead to very low sensitivity and, eventually, loss of the line’s structure and strength. 

Hence, you want to try to strike the right balance between stretch and sensitivity because, naturally, you need to know when the fish has caught your bait or has even caused the slightest movement around your line, while still maintaining strength and versatility.

6. Memory

Memory is your line’s ability to keep its shape when it’s unwinded. A line with high memory will not loosen after it has been unfurled from the spool; it will have angles, coils, and eventually tangles. That’s why, always try to go for the lowest memory possible to achieve smoothness and sleekness.

Frequently Asked Questions:

Should You go for a Monofilament or a Fluorocarbon Line?

Many variables can go into such a decision, but they all fall under one statement, which is what you need from your fishing line. 

How you want it to behave, what kind of fish you’re going after, and what sort of environment your line will be working in are also important factors.

To sum up, if you want a line that can tie top-notch knots and enjoys excellent stretch for over-the-water fishing, then a monofilament line will do perfectly for you. Also, if you’re a beginner, then a monofilament will help you as it does not have a steep learning curve, and it is quite affordable.

On the other hand, fluorocarbon fishing lines are a little bit more expensive, as they are more robust and in possession of excellent visibility.

What’s the Lifespan of a Monofilament Line?

This depends on the frequency of usage of your line and the competence of your maintenance. You have to always tend to any signs of breakage or abrasions as soon as possible. Still, the lifespan of a monofilament line that is being regularly used is around six months. 

Which Plastic Variety Is Monofilament Line made of?

Mainly nylon. However, lines that are designed for longer casts are usually made out of Dacron, polypropylene, fluorocarbon, or polyethylene.

Final Thoughts

Monofilament lines are an excellent choice for fishing. They enjoy perfect casting distance, affordable prices, good memory, good stretch, and unique visibility options.

To sum up, the most important things to know before purchasing a monofilament line or any line, to be honest, are what kind of fish you’ll be going after and what fishing environment you will be present in. These variables will weigh heavily on your decision.

If you want to go for a line that will check all the boxes, give you great strength, low memory, adequate stretch, and everything that you might need, then our top pick, the Berkley Trilene Big Game, is the best monofilament line.
