6 Best Fishing Line For Trout: Monofilament & Fluorocarbon

Having a hard time finding the best fishing line for trout? We got you covered.

You’re here because you know there are several types of lines on the market that’s best for trout fishing.

Monofilament, fluorocarbon, and braided fishing lines are the most common choices. It’s hard to tell which is the best since it’s up to you to decide which one works the best for you. However, some are more common than others.

In our experience, monofilament lines are the best to use to catch trout. Nevertheless, we’ve got a couple of recommendations for you to choose from below.

Why is Monofilament Best for Trout?

When it comes to trout fishing, monofilament line is often the best choice. This type of line is made from a single strand of plastic, which makes it strong and durable. It also floats on the water, making it easy to see and track.

Monofilament line is often less visible to fish than other types of line, making it a good choice for stealthy fishing. Additionally, monofilament lines are relatively inexpensive and easy to use. It comes off the spool easily and is relatively forgiving when it comes to tangles.

In terms of pounds we recommend 4-6 lbs for trout fishing with mono line. We recommend this because it gives you a good fighting chance against the fish, while still providing some give if the trout makes a sudden run.

All in all most anglers use mono line for trout fishing because of its strength, durability, and invisibility.

1. RUNCL PowerMono, Monofilament Fishing Line

Standout Features:

The RUNCL PowerMono fishing line is the best monofilament fishing line for trout. I used a 6 pound line with a 4 pound fluoro leader and had no trouble landing a 12 inch trout. The mono line is easy to put on the reel and has great color options. Green in particular as it gives a little extra visibility over clear. The line is also strong and held up well to multiple catches throughout the day.

One drawback is that the line at times was not taped at the end of the spool, which can lead to tangles. There were instances where I had a huge bird’s nest form at the end of the spool by the end of the day. Despite this, the RUNCL PowerMono fishing line is still an excellent choice for trout fishing.

2. Seaguar Blue Label 25-Yards Fluorocarbon Leader

Standout Features:

The Seaguar Blue Label is the best fluorocarbon fishing line for trout. It’s the most popular brand as it’s the “go to” trout fishing line of many experienced fishermen. It’s made of a 100% fluorocarbon leader material and is smaller in diameter than most others on the market. It’s been around for the longest time which is why most people have tried it before.

It’s among the best choices which is no surprise since Seaguar has invented this type of fishing line back in 1971. It has remarkable tensile and knot strength with impressive abrasion resistance. On top of that, it also absorbs shock very well.

Because it’s made of pure fluorocarbon, it’s practically invisible once under the water. Trout can’t spot it because it’s not reflective. Other types such as Monofilament look invisible but are quite reflective in water.

This product goes well for freshwater and saltwater fishing rods.

3. KastKing FluoroKote Fishing Line

Standout Features:

The KastKing isn’t actually pure fluorocarbon such as the Seaguar Blue Label. However, it performs similarly since it features a 100% fluorocarbon coat. The fact that it’s just coated with the material reduced its price significantly. In fact, it often costs about a half of the price of the full fluorocarbon line.

The KastKing FluoroKote is best for when you’re in warm weather and deep water. It sinks fast, and it has exceptional abrasion resistance. It’s also crucial to mention that it doesn’t absorb any water. It works well for all kinds of situations and baits you can think of.

The material under the coating is a copolymer that helps with its invisibility when under water. It doesn’t stretch, has higher density and works with almost all techniques and situations.

This is a good choice if you’re on a budget since it performs similarly at a fraction of the cost.

4. P-Line Floroclear Clear Fishing Line

Standout Features:

If you want the ultimate knot strength, you should definitely consider the P-Line Floroclear. This is actually a hybrid of fluorocarbon and nylon which gives a softer touch.

Another thing that’s quite amazing apart from the strength is how great you can cast it. P-line has created a tough product, and they’ve got it just right. It’s also crucial to mention that this one has low stretch so it won’t curl as most fluorocarbon do.

You can use it any way you like though it works the best as the main line. Its small diameter makes it ideal to catch regardless of the season you’re fishing in.

Many people say that P-Line works like mono with fluorocarbon specifications. This also makes it great for brass. Also, it costs less than pretty much every 100% fluorocarbon line.

5. Sunline Super FC Sniper

Standout Features:

The Sunline Super FC Sniper is one of the best choices if you’re using both casting and spinning reels. It’s versatile mostly because the manufacturer used triple resin processing.

The high-quality materials used in this process give it some remarkable characteristics. Sunline is resistant to abrasion, doesn’t stretch and has a uniform diameter. This means that there won’t be any thin spots, knots, defects or any kind of issues when you’re trout fishing.

Castability is impressive thanks to its overall strength low memory. It sinks quickly and is probably the best for heavy cover applications.

This product is strong and durable, but its best feature is probably the fact that it doesn’t tangle or stretch.

6. Stren Fluorocast Fluorocarbon Fishing Line

Standout Features:

Another popular fishing line choice is this all-American type. The Stren Fluorocast is made in the USA, and you’ll often see people use and recommend it as one of the top choices.

The Stren Fluorocast Fluorocarbon line is strong, as it’s made of 100% fluorocarbon. The abrasion resistance and toughness of this one are mostly why fishers use it. It sinks quickly so all your lures will go deeper in less time. If you know the way these work, you’ll know what to expect from Stren Fluorocast.

Many people say you’ll get the best results if you pair this fishing line with an 8 or 10-pound braided line. It does a great job as a leader, especially for trout fishing. Its small spool design allows it to work with a tackle box.

It’s invisible underwater because it’s made of 100% fluorocarbon. Its best specification is impressive abrasion resistance. For this reason, you can use it in all kinds of situations and both salt and fresh water.

Buying Guide: Fishing Lines for Trout

There are different factors you should consider when buying the best fishing line for trout such as weight, visibility, strength, and color.

Experience Level

The experience level of the angler is an important consideration when choosing a trout fishing line. A beginner or novice angler may not need the same features or specifications as an experienced angler. For instance, a beginner may want a line that is easy to cast and has good handling characteristics, while an experienced angler may prefer a line with more sensitivity that can detect even the slightest bites.

And so if you’re a beginner, monofilament is your default option. It’s easy to use, has a bit of give which helps with casting, and is affordable. Monofilament is also great for catching brown trout as well. 

But if you’re looking to step up your game, there are other types of lines available that may better suit your needs. Braid is a good choice for anglers looking for sensitivity – you’ll feel even the lightest bites – as well as strength; it doesn’t stretch like monofilament does so you can set the hook quickly. A fluorocarbon is also a good option for experienced anglers; it’s sensitive and durable and sinks quickly making it ideal for fishing in deep water.

Size Line for Trout Fishing

In general, you will want a light-weight line for smaller trout and a heavier line for larger trout. A good starting point is to use a size 8 or 10 line for trout under 10 inches in length and a size 12 or 14 line for those over 10 inches.

When deciding on the weight of the fishing line, consider the water conditions you will be fishing in. If the water is slow and deep, you’ll need a heavier line to make it to the bottom. If the water is fast and shallow, you’ll want a lighter line so it doesn’t drag in the current.

Finally, pay attention to the thickness of your line. Heavier lines will generally be thicker than lighter lines. This is important because a thicker line can’t fit through the same guides as a thinner line. Make sure you have the right size line for your reel.

Color of Fishing Line

Green color fishing line is often used by anglers targeting trout. The line is less visible in most water conditions, and it also blends in with the surrounding foliage, making it difficult for the fish to see. While some anglers believe that any color will work, green is often the best option when fishing in heavily wooded areas or around structure.

When choosing the color of your fishing line for trout, it is important to consider a few things. The first thing to think about is what water conditions you will be fishing in. If you are fishing in clear water, you will want to use a light-colored line so that you can see it well. If you are fishing in murky water, you will want to use a darker line so that it is less visible to the fish.

The other main consideration when choosing line color is the visibility of the bait. If you are using brightly-colored bait, you will want to use a line that matches or contrasts with the bait color. For example, if you are using pink bait, you would want to use a pink or red line. If you are using bait that is more natural-looking, you can use a line that is less visible, like green or brown.

Finally, if you’re a beginner, then yellow colored fishing line might be the best choice since it’s very visible in the water. It makes it helpful for beginners to keep track of the line.


The strength of your fishing line is one of the most important factors in determining your success when trout fishing. A strong, durable line will withstand the pulling and fighting of a trout on the end of your line, while a weaker line may break or snap under the pressure.

When choosing a fishing line for trout, it is important to consider the size and weight of the fish you are targeting. Larger trout can be quite powerful, so you’ll need a line with enough strength to handle their fight.

There are a variety of factors to consider when choosing a fishing line for trout, but overall strength is probably the most important. The best way to determine the strength of a particular line is to check its pound test rating. This number reflects how much weight the line can hold before it breaks.

A line with a high pound test rating is ideal for larger trout, while a line with a lower rating is better suited for smaller fish.

Fishing Line Setup

The only way you’ll be successful in catching this shy fish is by selecting the best fishing line for trout setup. Without it, it doesn’t even matter which bait or technique you’re using.

Fluorocarbon line is the popular choice when it comes to fishing lines. Trout is actually quite shy which is why fluorocarbon is a much better choice than the braided fishing line for example.

These fish have amazing eyesight that’s probably better than any other fish. They have similar eyes like humans with a better ability to see ultraviolet frequencies.

This is the type that’s nearly invisible when underwater, so the shy trout is less likely to notice it. Braided might be better for other fish such as golden perch and yellow belly fish.

Trout have amazing sight so they can spot most lines quite easily. For this reason, trout fishing with monofilament line might make it harder to actually catch any.

This fish has monocular and binocular vision which allows them to see in the opposite way of where they’re swimming. More so, they see in practically every direction at the same time and can move their eyes independently. line

Can Trout Spot Fishing Lines?

Trout can definitely see fishing lines. It’s funny, but they’ll be suspicious of even the slightest showing of the line regardless of the lure you’ve attached.

It’s crucial for your success to keep in mind that this fish is easily scared. Choose only the line that’s invisible once in the water since all your chances depend on this.

Luckily, most lines made for targeting trout are barely visible. Combine this with an appropriate lure or bait, and you’ll have much higher chances of catching trout the next time you’re in the water.

The Three Main Lines for Trout Fishing

Fluorocarbon Fishing Lines

Fluorocarbon fishing lines are better for trout because it’s barely visible underwater, so trout cannot see it. It has no color and is completely clear plus you’ll feel the bite quite clearly. Also, fluorocarbon lines are very strong and durable, which is important when casting in windy or rocky conditions.

Fluorocarbon is very similar to monofilament in terms of stretching abilities. It’s not elastic so you can feel when the fish bites pretty much the same second. Also, fluorocarbon lines sinks better, so it’s best if you want to place the bait deeper in the water.

Probably the only downside is that fluorocarbon is a bit more expensive than most others on the market. If you’re just starting out, it might be too much when you’re buying all your equipment. However, if you’re looking to catch trout, you should try these if you have a chance.

Monofilament Fishing Lines

Monofilament fishing lines are another popular type of fishing line trout anglers use. It’s mostly recommended to beginners since it’s versatile and works for all kinds of fish. On top of that, it’s affordable so and usually much cheaper than fluorocarbon option.

It’s more elastic, and though people often think that’s bad, it’s not. Lines that aren’t elastic at all might break easier when the fish bites. Monofilament lines will stretch just enough instead of breaking. For this reason, it works well with most species.

It’s also important to note that this one won’t sink as fluorocarbon does. It actually floats which can be both good and bad depending on the bait you’re using. You might need to do some more in-depth research on this if you want to be sure you’re doing it right. Still, if you opt for topwater baits, choose monofilament line. Otherwise, fluorocarbon is a good choice.

Pay particular attention to the drag setting of your reel. Because it stretches, it could snap quickly unless you use it with care.

Another thing you should know is that mono has high memory. If you don’t use it for too long, it will most definitely curl up on your spinning reel. This will make it practically unusable. Also, make sure to avoid bright colors since trout will spot them from afar and you’ll just end up throwing your money.

Try it out several times in different weather conditions and see if it works for you.

Braided Fishing Lines

Regardless of whether you’re trout fishing with lure or bait, you can use a braided fishing line in combination with either fluorocarbon or monofilament. The trick is to use braided as your mainline and one of the other two as your leader line. This will save you some pennies, but you’ll still be able to catch some trout.

Using a full fluorocarbon as the mainline is a bit expensive for some especially if you’re just starting out. Braided lines are stronger but have the same thickness which is exactly why as many people opt for it.

It’s also a bit faster since it doesn’t stretch and has a thinner profile. This allows you to feel the bite very well. Plus, it has low memory, so it’s ideal for trout spinning reels. It’s also long-lasting as it has great abrasion resistance.

Its most significant setback is the fact that it’s highly visible. For this particular reason, it’s not recommended as a leader line. Trout will spot it every single time since it has no transparency whatsoever.

Using a long leader fishing line on a short rod is a bad idea if your mainline is braided. You’ll have lots of trouble with accuracy and probably no success in catching trout. However, you can make it work by pairing a rod with a fluorocarbon leader. This will help not to scare trout though it will do very little for the accuracy.

As you can see, there’s a way of making the braided line work for trout. It’s an affordable solution, but you’ll most definitely have to pair it with another kind. On its own, it does no good, and trout most probably won’t even come near it.

What is the Best Line for Trout in Clear Water?

The best line for trout in clear water is 4 to 6 pound test fluorocarbon.

This line is less visible in the water and will help you get more bites.​ Make sure to use a leader as well, as this will help protect your line from getting tangled in underwater obstacles. A good leader size is 12 to 18 inches long.​

What is the Best Line for Trout in Stained Water?

Fluorocarbon is the best choice for trout in stained water, hands down. It has a near-invisible sheen and is virtually impossible for fish to see.

In addition, fluorocarbon sinks quickly and has a high abrasion resistance, making it ideal for fishing in fast-moving water or snaggy conditions.​ However, you can go with monofilament as well if you prefer. Just be sure to use a line with a high pound-test rating to handle the big fish in stained water.

What Line to Use for Trolling Trout?

You want to use a heavier line if you’re trolling for trout. The reason why you want a heavier line is that you need to get the bait down deep. If you’re using a light line, the trout will be able to see your bait from a distance and they’ll swim away before you even have a chance to cast your line.

A heavier line will help you get your bait down to where the trout are hiding, so they won’t be able to see it. This will give you a better chance of catching them. Make sure to use a sinking line if you’re going to be trolling for trout, so your bait will sink down to where they are hiding.

What is the Best Ice Fishing Line for Trout?

You can use a 10 to 15- pound braided line with a fluorocarbon leader. You’ll want a fluorocarbon leader with the braided line because it is less visible in the water.

If you are using a spinning reel, use a 6-8 pound monofilament line. You’ll want to use a fluorocarbon leader with the monofilament line because it is less visible in the water.

Final Thoughts on the Best Fishing Line For Trout

Knowing a little about the fish you’re trying to catch is always a good idea. Trout is specific, and unless you get to know some facts and characteristics, you’ll probably struggle to catch it.

While you have to consider many factors, getting the right fishing line is probably the most important. Fluorocarbon is often the best fishing line for trout and it’s the easiest to use since this species has excellent sight and is shy. Others might work too but require a bit more experience.
