The Best Fishing Line For Trout: What Guides Use 2024

Use the best fishing line for trout to catch big brown trout like this.

In this article, I will discuss the best fishing line for trout fishing and why I and other trout guides only use premium fishing lines. Learn which sizes and types of fishing lines are best for different methods and when fishing trout in rivers and lakes.

The best fishing line for trout fishing on small streams for newer anglers is the 6-pound Suffix Elite monofilament line, but there are times when 6-pound or 8-pound line is a better option. For more advanced anglers fluorocarbon and braided lines might be a better option depending on the method.

Monofilament lines are used by most river anglers and are used by fishing guides that use multiple methods with one rod, but for specific methods such as casting lures, jig fishing, or trolling, lines like fluorocarbon lines or braided lines will have some advantages over mono. All lines have pros and cons to them, so let’s find out what line is best for you.

The 3 Best Trout Lines

The three best trout lines are Monofilament, Fluorocarbon, and Braided lines, and each one has advantages and disadvantages depending on the type of water you are fishing and the type of method that you are using.

  1. Braided Line: On my fishing reels that I use for casting lures in lakes or in rivers, I like to use braided lines for a number of reasons which I will discuss below.
  2. Fluorocarbon Line: Many skilled anglers and guides will prefer a quality fluorocarbon line when casting lures in rivers or when using methods like Drift Fishing or bottom bouncing.
  3. Monofilament Line: On the reels that I use when I am float fishing for trout in rivers, I prefer and use a premium monofilament line, and I will discuss the benefits of monofilament below and which ones are best.

When I am using reels that I use for multiple methods, instead of changing lines, I always prefer a premium monofilament fishing line for trout fishing which is why I often recommend mono over all other lines.

Is Mono The Best Line For Trout Fishing?

When I use a mono line for trout fishing with both bait and with lures, I find that it always works best with a good fluorocarbon leader setup.

I still believe that most of the time float fishing is one of the most productive methods for catching trout in rivers, especially if you use the right leader setup. The trout fishing leader setup that I use and teach my clients works better than most other leaders that I have tried.

The major benefits of mono are:

  • It is sold everywhere
  • It works well on all reels
  • It works well with all trout fishing methods
  • It also comes in many colors (see below which is best)
  • It comes in all the needed sizes for fishing trout
  • It’s the least expensive of all the fishing lines

However, not all monofilament lines are created equal and some are cheap and not very good while other mono lines are excellent for trout fishing. There are also some disadvantages to Monofilament lines.

The Best Monofilament Line For Trout Fishing

You must use a good monofilament line for trout fishing if you want to be able to fish well with mono. The best monofilament lines for trout fishing are premium lines or what I call performance lines, and I will discuss the advantages of these lines and the disadvantages of the cheap lines.

If you want the best fishing lines for trout that are made from premium mono, these are the best that I have used. I will also discuss the best sizes below this.

Other Great Mono Lines For Trout Fishing

  • River Line: The Ande Premium Line is a very popular and well-liked line used by river anglers. Guys will use this for both float fishing and for lures or other methods.
  • General Purpose: Trilene XL is not what I would consider a premium line, but it is an old standard used by thousands of fishermen. It is also inexpensive and is still a decent line for trout fishing. Check it out at this link: Trilene XL.
  • For Wooded and Rocky Rivers: The P-Line CXX X-Tra Strong Monofilament Line is a good line to consider when fishing in rivers with lots of snags and when a little extra strength is required.

One of the disadvantages of mono is that it can have line memory which makes casting difficult. Line memory creates line coils when it comes off the smaller spinning reel spools and that can affect the way the line goes through the guides and the way it sits on the water. Line memory and line coils can cause problems.

Cheap lines are the worst for line memory and line twist, and that can also cause more tangles and problems, so avoid cheap lines. Cheaper lines that are also thick are even worse.

Good lines like the Suffix Elite line are much better and are lines that I would consider as a performance fishing line or, as they call it, a premium fishing line.

Performance type monofilaments will help you cast better, and they will help you catch more fish when compared to cheap crappy lines because they perform better allowing for better hook sets, stronger knots, and less memory, and they go on the reel better with less line twist.

I find that performance lines can also offer features like being limper or stiffer, or they will be stronger at a thinner diameter which is exactly what you want when you are fishing for line-shy trout.

Some of these performance lines can also have UV coatings to make the lines last longer, some will have less stretch and some are slick for better casting.

How To Straighten Fishing Line

Even good fishing lines can have some line memory if left for a long time or if left for too long in the sun or if it’s exposed to heat.

The easiest method to straighten the monofilament fishing line is to stretch it by tying it to something stationary and then walk back about 1.5 times the length you could normally cast and then pull or stretch the line.

Just be careful not to pull too hard or it could break the line near the reel and you will lose a lot of line. This method often works on good-quality lines but not so well on cheap lines.

How Long Does Monofilament Line Last

Monofilament that is stored indoors and out of direct sunlight will last about 3 years. How I test my mono is I will tie my best knot onto a large hook and I will pull it to test how strong the knot is. If it’s hard to break it’s still good, but if it breaks easily, it’s time to recycle it.

Some local tackle shops will take back your old line for recycling.

The Best Fluorocarbon Fishing Line For Trout

Fluorocarbon lines are arguably the best fishing lines for trout in rivers for certain methods, and fluorocarbon definitely has its advantages as well as some disadvantages, but the really important thing with fluorocarbon is to buy the right one.

Cheap fluorocarbon lines cause a lot of problems and give fluorocarbon a bad name but it doesn’t need to be that way.

The primary advantage of the fluorocarbon line is that it is the most invisible fishing line to the fish and it’s very abrasion-resistant which can be great if you are fishing around a lot of rocks or logs. It also tends to sink and has less stretch than monofilament, making it the best fishing line for trout.

Since the fluorocarbon line tends to sink, it is good when fishing with lures, but I avoid it and do not recommend it when float fishing which I give reasons for below.

There are many advanced river anglers and river guides that love fluorocarbon lines for lure fishing or when using jigs, or for methods like Drift Fishing or bottom bouncing,

If you do decide to use a fluorocarbon line for trout fishing it is very important to use a high-end fluorocarbon line from a reputable brand. This way you will get a good line that casts well with the type of reel that you use.

The downside to fluorocarbon is that it can be stiff and it can cause problems on spinning reels, and because of that I usually do not usually recommend it to beginners or average anglers for their spinning reels.

Some anglers claim some fluorocarbon lines are stiff right out of the package and they have seen it practically jump off the spool of their spinning reels causing all kinds of problems. I have had clients have problems like this and it’s often it’s due to the line being, or they put it on wrong, or it’s just a low-quality fluorocarbon line that is not good for casting.

Another downside is that a high-quality fluorocarbon line can also be 2 to 3 times more expensive than mono lines.

However, some of the high-quality fluorocarbon lines are more supple and are good when using baitcasting reels and spinning reels.

Often, when using a fluorocarbon line, any slack in the cast or after the cast can cause problems on spinning reels.

Best Fluorocarbon

The best fluorocarbon lines for spinning reels when fishing for trout are:

  • Seaguar Inviz-X fluorocarbon line is one that I have used for many years and is often my go-to line for leaders and for casting lures. This might be the highest-rated fluorocarbon line in the world.
  • P-Line Fluorocarbon 100 % Pure Line – The P-line Fluorocarbon is a good line used by trout anglers, and it is one of the highest-rated lines available.

Due to the potential problems and the higher prices, also because it’s less versatile, and because you can easily use a fluorocarbon leader when fishing with monofilament lines, I do not use fluorocarbon as my main line on most of my spinning reels.

I would also never use a fluorocarbon line on any reel that I float fish with because it sinks, and for float fishing, you always want the part of the line above your float to be buoyant when float fishing.

This way, you can mend easier, and you will have less line drag. You will also have a better hookset with a floating line when float fishing.

Braided Fishing Line For Trout

I have also used braided lines when float fishing with spinning reels, baitcasting reels, and even with Centerpin reels, but you must use a good leader setup and know how to properly secure it to the reel.

The Best Braid For Trout

Expert lure anglers and guides know that when fishing for trout in a river or lake with jagged rocks or with lots of wood and sunken trees, you want to use fluorocarbon and not braid because the braid will cut into the wood, and you’ll get hung up. The sharper rocks can also cut through the braid.

The advantages to using braid when float fishing or bottom bouncing is:

  • No stretch, so long hooksets are better
  • Most braided lines float, which is great when float fishing
  • Braided line has very low or no memory
  • Braided line comes off the spool smoothly
  • Brained lines are extra strong for their diameter
  • Braided lines are more sensitive to help you detect strikes when you are bottom bouncing

The disadvantages of braided lines when float fishing:

  • You need a fluorocarbon leader or the trout will see the line.
  • Because there is no stretch, it is more common to break fish off on the hookset or when fishing with a leader.
  • Braid is not as easy to tie knots with, and you will need specials knots for braid.
  • The float caps that hold the float to the line can break more often with a thin braided line.
  • Braided line can freeze in the winter because it can absorb water and freeze, and even the entire spool can freeze solid if you dunk your reel into the water in below-freezing temperatures.
  • Not properly securing a braided line to a reel can cause the entire chuck of line to spin freely around the spool making it impossible to reel in. This can occur if you tie the braid directly to the spool without a mono backing or taping it to the spool.

Sufix Nanobraid Line

The downside to braided lines is that the fish may see the line if you tie it directly to the lure, so you might require an 18-inch to 36-inch section of 8 to 12-pound fluorocarbon leader. I use a leader all the time.

Leaders – Do You Need Them?

A leader is simply an added section of line that goes on the end of the fishing line. This is where you tie on your bait or lure and it is a good idea.

When it comes to trout fishing, wire leaders are bad! Anytime I see an angler with a wire leader on while fishing for trout I know that guy has very little chance of catching any sizable trout unless he’s using a fast lure.

Leaders for trout fishing are primarily made from Fluorocarbon. The purpose of a leader is to hide the thicker mainline from fish’s sight and/or to help with abrasion from rocks or wood.

The leader can be the same size as the mainline that you are using or it can be slightly lighter. Almost never will my leader be stronger than my mainline.

I almost always use a leader when fishing for trout in rivers and lakes.

Best Lines For Different Types Of Reels

Some fishing lines work better on different types of reels than others but the truth is you should put whatever line on your reel that suits your situation.

Spinning reels work best well when spooled with monofilament lines however if left on too long and not used the mono can have bad line memory and therefore line twist.

Braided line, and Copolymer lines also work well on spinning reels.

Few fluorocarbon lines work well on spinning reels and bad fluorocarbon lines can cause all kinds of problems on spinning reels so stick with the ones I recommend.

Baitcasting reels work well with almost all types of lines including fluorocarbon lines.

Best Line For Centerpin Reels

The two best lines for Centerpin reels are mono like the Raven Mainline mentioned above or braided line like Power Pro.

I never use fluorocarbon lines on a Centerpin reel because they are heavy and they sink which causes all kinds of problems with mending and hook sets. See my page on the best lines for Centerpin fishing where I list all my tested and proven lines.

The Best Fishing Line For Trout In Rivers

There’s a reason why the best trout line is different for river fishing versus lake fishing is because of the different methods used and because of all the rocks and logs found in many rivers.

The best fishing line for trout in rivers will depend on the method that you are using but if I was to choose only one type of fishing line it would be a good quality monofilament line that is great with all methods of river fishing.

What Is The Best Fishing Line For Trout In Clear Water

The best line in clear water is the fluorocarbon line. However, You can have clear water in both lakes and rivers and to be honest with you, there are other factors listed above that will determine the best line in clear water and I would recommend sticking to those reasons.

As an example, in clear water lakes when trolling, the best line is braid, but only if you use a long fluorocarbon leader.

But in any water with lots of wood, sunken trees, or sharp rocks, the best line would be fluorocarbon.

When float fishing in clear water, mono is still the best line to use, just make sure you also have a good fluorocarbon leader.

What Is The Best Fishing Line For Trout In Dirty Water

You will often see the water of a trout river get dirty after a rain. So what is the best line for trout in dirty water? Since having a stealthy line is not an issue, the real answer is any line will work in dirty water but the line you should use depends on the method you are using and if it’s rocky and wooded or not. See Trout Fishing After Rain – Expert Guide Tactics And Tips.

What Is The Best Line For Trolling For Trout?

You could use any of the lines mentioned above for trolling for trout. Most anglers still use monofilament when trolling for trout, and that is ok, but Fluorocarbon and braided lines are often the better lines for trolling for trout.

The extra thin diameter on the braided lines will help get your lures deeper and provide you with a more solid hook set with zero stretch. For this reason, braided lines are the best lines for trolling for trout.

However, braided lines are more visible to the trout so always add a 2 to 6-foot fluorocarbon leader to them.

A fluorocarbon line is also a good option due to less stretch and is more invisible to the fish.

Does Line Color Matter?

The simple answer is yes, the color of your fishing line does matter simply because some colors can be seen by the fish easier than other colors. I recommend that the section of the line that is nearest to the bait or lure should be clear or green or that you use a clear floruocarbon leader.

The line near the bait should not be yellow, orange, or colored at all.

However, if you have read my articles on float fishing you will see that I do recommend bright colored lines, in fact, that is mostly what I use when guiding and fishing but I always use a 3 to 5 foot or longer fluorocarbon leader.

The reason I use colored lines is that colored lines provide anglers with the advantage of being able to see the line out of the water which helps the angler get a better presentation.

I also use a 3 to 4-foot-long fluorocarbon leader if I’m using brightly colored lines when casting lures for trout or steelhead, or when bottom bouncing. I simply attach the leader to the line using a Triple Surgeons know, Double Uni Knot, A Tippet ring, or a micro swivel.

Is Copolymer Line Good For Trout Fishing?

The copolymer line is very similar to monofilament except that the advantage to copolymer lines is better breaking strength, better knot strength, and less line stretch.

Copolymer lines tend to sink more which is a disadvantage for anglers that want to float fish. Some copolymer lines are less supple, and copolymer lines are often more expensive. For these reasons, I don’t use copolymer lines.
