Factors To Consider When Buying Mono Fishing Line

Like anything in life, it’s important to remember that one size doesn’t always fit all, especially when it comes to your monofilament fishing line. 

Certain lines are going to perform better than others, depending on a wide variety of factors.

Here are four factors you need to consider before purchasing the best monofilament fishing line for your next fishing excursion.

Understanding Line Stretch

Line stretch is important for anglers who may occasionally need some line forgiveness. 

A monofilament line can stretch up to 25 percent or more, making it a great ally if you’re prone to setting the hook too hard or if your line drags. 

A decent stretch also works to prevent fish from becoming unbuttoned (where they lose the hook), particularly helpful when you’re trying to pull in a fish putting up a big fight, like a smallmouth or largemouth bass.

Knowing Your Diameter and Knotting Capacity

It’s important to consider where you’re going to be fishing before selecting a line, especially if it’s a body of water that’s known for currents or unforgivable terrain. 

A larger diameter line is often more durable than thinner lines, especially against sharp rocks and underwater structure, offering a bit more protection in case you hit something sharp. 

Keep in mind, however, that a larger diameter can often mean higher visibility, which might spook fish away. But a thicker lines is also more likely to hold larger knots.

Understanding Line Strength

The line strength is one of the most important factors to consider when purchasing a new fishing line, particularly if you’re after some big-game fish. 

Tensile strength is the amount of strength (measured in pounds) applied to a line before it breaks. It is crucial to select the right line strength for your reel before you head out or be willing to face exhaustion and disappointment on the water. 

After all, the last thing you need is putting up a good fight for a while to have the line snap under pressure. As a rule, you should opt for a tensile strength equal to the size fish you are hoping to land. 

The Importance of Line Memory

When it comes to fishing, less is usually more. And this stands true with line memory too, especially if you’re wanting less friction when casting.

Line memory is the material’s natural ability to retain the shape of the spool after it has been unwound. Ideally, you want a fishing line that doesn’t coil or curve when released.

 A low memory monofilament fishing line will hold straight after releasing it, whereas a high memory line will likely stay coiled and curved. 

A coiled and curved line decreases your casting range and increases the likelihood of knots and snags. Always opt for a line that has little to no memory for a better cast.

Frequently Asked Questions

Below, we’ll go over a few of the most common questions asked by anglers when shopping for monofilament fishing line. 

Is a monofilament line better than a braided line?

As a short answer, it depends. Both monofilament and braided lines have their benefits and drawbacks, but monofilament can be easier to use. 

Monofilament line has a much higher abrasion resistance when compared to braided lines, making it less likely to cut against sharp objects. Additionally, monofilament has a higher line stretch compared to braided line, helping keep hard-hitting fish on your line—instead of breaking it clean away. 

Monofilament is also easier to tie, easily holding your lure in place with any knot. For most anglers, a monofilament line is a cost-effective solution for most fishing trips.  

Is a mono-line better than a fluorocarbon line?

If you’re comparing mono to fluorocarbon lines based on cost, monofilament will always be more cost-effective. 

Aside from the cost, fluorocarbon lines have several advantages over mono-lines, although that doesn’t always make them the ideal selection for your next trip. 

In terms of visibility, the fluorocarbon line has light refraction capabilities that mimic freshwater, making it almost invisible. It also holds stronger than mono-lines and offers a higher abrasion resistance too. 

However, fluorocarbon is denser than water, making it sink quickly once cast. Monofilament suspends itself in water, making it a strong winner in this category.  

Does a mono fishing line go bad?

Similar to produce, meat, and dairy products, monofilament fishing lines do, in fact, have a shelf life before they start to go bad. This is true even for lines that haven’t been removed from their packages. 

One major issue with a monofilament line that has been kept beyond two to three years is the impact memory that it will hold in the line itself, which will cause weakened sections throughout your line. 

How often should you change your mono-line?

Unfortunately, there’s not a “one size fits all” approach to how often you should change your mono line.

If you’re only using your line periodically (think a few weekends a month), you’ll want to change your line once or twice a year. But if you’re an avid angler, you may want to change your mono-line more frequently, ideally every six to eight weeks.

Always make sure to check your line for any imperfections before use, especially if you’ve stored your line for an extended period. What may have started as a small nick in your line the previous season can substantially expand over time. 

What color is best for a monofilament fishing line?

With a host of different colors available in the monofilament market, choosing the best option might seem difficult. But rest assured, choosing a color is as simple as determining what you’re wanting to use it for. 

If you’re looking for a line you can monitor under the water, opt for a high-vis color like yellow or bright blue. Keep in mind that these colors will be more visible to the fish too, although aggressive fish tend not to mind as much.

On the other hand, for reduced visibility in the water, opt for a clear or green color line. Both colors are likely to blend with surroundings, which will help reduce visibility.

In Conclusion

Although many only think about the best fishing rod, lures, and bait, using the right monofilament fishing line is just as important as the rest of your gear.  

However, not all monofilament fishing lines are created equal, and choosing the right line takes a certain level of care and a lot of consideration.
