5 Best Float Fishing Lines For 2021

Float Fishing Line

I have been float fishing with spinning reels and Centerpin reels for over 30 years and as one of the top river guide around the great lakes region, I know from experience that some float lines work better than others.

What Is The Best Float Fishing Line?

The best float fishing line that I like and use on all my steelhead float rods is 8lb Raven Mainline in the high-viz yellow color. The best float fishing line for trout is 6 pound Raven Mainline. There are a few other good options that some anglers prefer and you need to know how to set up the leader properly for a colored line.

8-pound line is what I use for great lakes steelhead fishing but If you are float fishing for trout or salmon the line will be different.

I discuss the best line sizes for salmon on my page Float Fishing For Salmon: Advanced Tactics for Great Lakes Salmon, and I discuss the best line sizes on my page Float Fishing For Trout- Expert tips and tactics for more trout.

Using a great float fishing line like the Raven Mainline for any species will improve your drifts and prevent some of the problems that can occur when using the wrong line or the wrong size of line. The type of line, the size or weight of the line, the color, and even buoyancy of the line are all important and I will discuss that in this article.

You could try and use braided lines or fluorocarbon lines but the best float fishing line is a monofilament line. A good mono line for float fishing line should be buoyant, lightweight, thin, strong, have low memory, and cast easily.

Float fishing lines can be colored so you can see them easily or they can also be clear and I will discuss the benefits of the line colors below.

Using a float fishing line that has been tested and proven by thousands of anglers just makes more sense. Many of my clients come out with the wrong lines and they struggle with getting a good presentation or they have lots of problems.

If you ask enough anglers you will get lots of different opinions on which line is the best simply because most anglers haven’t tried enough lines to know there is a difference.

I’ve has my hands on probably over 500 float reels and I have used just about all the different lines that anglers use when float fishing, and trust me, there is a difference. I will discuss this all below.

The Best Line For Centerpin Fishing

FishUSA.com is the best place to buy river fishing gear and brands like this KingPin reel and other brands that specialize in river fishing.

The best line for Centerpin fishing will need to have low memory, be thin but still strong, and will float. The best line for Centerpin fishing is the Raven 10 pound Mono Mainline. Another great line that anglers like is Sufix Elite in 8-pound test.

If you are a trout angler in smaller trout streams the best float fishing line is 6 pound Raven Mainline.

A line that is too thick and a line that sinks can cause a lot of problems and affect your presentation and your hooksets. I will get into that more below.

A thin line and a floating line can improve your presentation and give you a better and longer drift and can also improve your hook sets.

There are a few other good lines and some not-so-good lines.

The float fishing line is also known as the mainline to differentiate between the line on the reel and the leader line. You may see that some companies call their line the mainline especially if they are companies that specialized in Centerpin fishing.

The Best Line For Float Fishing With A Spinning Reel

I have used a few good lines for float fishing with a spinning reel but I have narrowed it down to only 2 lines. The best line for float fishing with a spinning reel is Sufix Elite Premium Monofilament Line in 8-pound test. Another great line is the Raven 8 Pound mainline.

These two lines are also popular with other float fishing anglers around the great lakes region.

Float Fishing Line Color

Centerpin Line Color
Brightly colored Centerpin lines are best if you know how to properly set up your leader.

Float fishing lines come in many different colors and many anglers will have a different opinion on which color they prefer. There are advantages to a brightly colored line and I prefer bright colors like yellow and orange and I will explain why.

Clear or green lines are popular with a lot of anglers and they use them because they believe that colored lines can spook the fish. But do they?

Can Fish See Colored lines?

Fish can see colored lines especially in clear water with slow-moving baits, so it is always best to use a leader that is long enough to keep the colored line far enough away from the bait that the fish don’t see it.

When float fishing, I always use a colored mainline and I highly recommend them!

If you do not set up the leader properly then yes, bright-colored lines will spook more fish however many anglers do not set up their line and leader properly even when using clear lines.

Float Fishing Setup for Colored Lines

One of the reasons anglers do not setup the leader properly is that many older and very popular float fishing sites have leader diagrams that recommend putting the split shots on the mainline which runs down to a short leader that your bait goes on. This is not the ideal way to set up a leader for float fishing.

In fact, there is no way that I would be able to have my clients hook over 500 steelhead a month with their leader setup the way most diagrams show, instead, it would be closer to 100 fish hooked.

If you make the mistake of putting your weights on the colored mainline with a short fluorocarbon leader then the colored line is close enough to the fish that it will likely spook them.

What many anglers that use clear lines don’t realize is that putting your split shots on a clear mainline can also spook fish because the mainlines are thick and they are usually made of mono which is not invisible under the water like fluorocarbon is.

If you use what I call a shot line on your leader you can use bright colored lines without spooking the fish because it keeps the colored line far enough away from the fish that they will never see it. With the proper leader setup, you will get all the benefits of the colored line without spooking the fish.

Whether you use a colored line or not, you should use a leader that is 3 feet or longer and made from fluorocarbon. You can see the shot line and the leader setups that I use on my page 5 Most Effective Float Fishing Leader Setups. These are proven to be the most effective leader setups you can use.

Colored Lines For Float Fishing Are Better

I believe that bright colored lines have more advantages than clear or darker lines, especially as a beginner. The main advantage of a bright-colored float fishing line is that it makes it easy for you to see the line so you can manage and adjust it better when needed.

Bright colored lines are all that I use on my Centerpin reels and since I often catch more fish than most anglers on the river, I know for certain that a colored line combined with a good leader setup will not spook fish.

Bright lines are also much easier for other anglers around you to see so they are less likely to cast near or over your line and they can follow your line down to find your float easier just like you can.

I also use bright colored lines to help teach anglers about proper line positions and mending. I always struggle to teach anglers how to float fish well when I can’t see their clear line.

Therefore I highly recommend going with a bright-colored line especially if you are new to Centerpin fishing and if you are using the right leader setup.

Even as a veteran float angler of 30 years, I only use colored lines which shows that they are not just for beginners.

Float Fishing Lines That Float Are Better

I put this client at the top of the pool so he could fish it more effectively. You can see where the river goes from shallow where he is standing to deeper where his float is.

Some float fishing lines are heavier than others. Fluorocarbon as an example is known to be a denser line and it sinks, as does some copolymer line and even some heavier monofilament lines.

The best float fishing lines should be strong but also as thin as possible and they should float or be neutral buoyancy. Thicker, heavier lines sink!

When the line floats it can easily be mended if needed, it doesn’t get dragged around by the current which can pull the float in an unwanted direction, and your hook sets are easier because your line lifts up off the water better with a floating line.

Lines that sink cause all kinds of problems. Some brands of lines that are made for tough fishing conditions like pike or bass fishing around rocks don’t work for float fishing and there are other lines that are much better because they are limper and are more buoyant.

What Pound Test Mainline Should You Use For Centerpin Fishing?

Best Float Fishing Lines
Big Steelhead require light leaders and the right size mainline.

The best pound test for great lakes steelhead is 8 pounds however there are some rivers and situations that might require 10 pounds or more.

I go into great detail on what the best pound line is for float fishing and what I use for great lakes and west coast rivers on my page What Pound Line Is Best For Centerpin Fishing.

I have been testing lines for over 35 years and I always recommend going with as light a pound test for your mainline as possible and there are a few good reasons for it with the biggest reason that you will catch more fish.

It’s important to use the correct line size for the steelhead and the rivers that you fish, and I choose the size of the line by the size of the heaviest leader that I need to use for the steelhead in my rivers, and I upsize it by 2 pounds.

Why not just go with a heavy line?

Some anglers think that steelhead are big so why not just use 20-pound test line and not worry about it. Unfortunately, I see these guys come out with me on guide trips or lessons and they can’t even get good enough drifts to catch a steelhead because the line is too heavy. The simple truth is that an extra heavy line will cause problems, which I will discuss below so lighter lines are always best.

Why does the leader matter? The leader is a critical part of your setup. If you use a leader that is too thick the fish will see it, and if you use a leader too thin the steelhead will just keep breaking you off.

I have tested leaders for over 35 years so I know exactly what works for me on great lakes steelhead in all conditions. If you are not sure what leader size you should be using, I discuss leader sizes and my page Best Steelhead Leaders For Float Fishing.

Some anglers believe they are fishing for big steelhead so they need a 10lb or 12lb or even 14lb test leader to be able to handle those big fish, they are usually wrong, a few exceptions apply.

I have fished rivers all around the great lakes and have been able to consistently land steelhead with 0.20mm diameter line. That size is thin enough that the steelhead will eat my baits but still strong enough for me to fight and control and land steelhead up to 16 pounds.

So if you only need to use a 0.20mm diameter line which is about 8lb test (some brands) just to get the fish to bite the bait, then having a 0.28mm (12 – 14lb test) mainline is just useless because you can’t even use all that extra strength of the mainline anyways or you will just keep breaking off at your leader.

Here is the catch, you can’t just use any brand of 8-pound leader and then just use any brand of 10-pound line!

You see, many leaders and mainline lines are not rated properly. On my leaders page, I discuss brands with 4 pound, 6 pound, and 8-pound leaders labels that are all 0.20mm in diameter, and after testing them I found that they all break at roughly the same pound of pull (about 8 pounds).

On top of that, many, if not most brands of mainline in the 10-pound range are closer to 0.28 to 0.32mm which is actually closer to 16 pounds breaking strength and therefore too heavy.

This is why I always recommend and buy my leader and my mainlines based on the diameter size and not the pound test rating on the label. Honestly, most brands lie about how strong their lines are and if they say their line is 10 pounds, it’s likely closer to 20 pounds which is not what you want when float fishing.

What is the problem with heavier lines? There is a reason I recommend and use certain lines in certain line sizes. In my testing, I have found that heavier lines tend to sag and cause a belly in the line between the rod tip and the float which can cause unwanted tilting of the float.

A thinner and lighter line won’t do this and it will give you a better line angle and a better float angle.

If you don’t know why the tilt and angle of your float matters, you are going to miss opportunities for a lot of fish, which is why I highly recommend you read about the 5 fundamentals of good float fishing that I teach all my clients. You can read about that on my page Float Fishing: Tips From A Pro River Guide For More Trout

I find that thinner lines also don’t sink as much as heavier lines do, and higher floating lines are always best. This is why you never want to use Fluorocarbon lines when float fishing – they sink!

I also find that thinner lines cast better and cast farther than thicker heavier lines. Thinner lines are more manageable than thicker lines.

Best Centerpin Mainline
Thicker mainlines tend to have more problems so it’s best to go as thin as possible. I believe my client told me this was 12 pound test which would likely break at 20 to 22 pounds. He had problems all day with this line.

Many of my hardcore steelhead buddies will actually use a float fishing mainline of 6lb test because it casts better and tangles less. See the chart below for a guide of what pound test line you should buy.

The float fishing line strength can also depend on the type of water you want to fish and the type of fish you will be targeting.

As an example, on rivers that are large and deep like the Niagara river or some west coast rivers, or on rivers that you can’t walk along the bank easily to chase a fighting fish, you may need to go with a heavier line so you can pull them back.

On smaller rivers where you can easily chase a fish up or down the bank, you should use a lighter line that casts and fishes better. See my size recommendations below.

How Much Line To Put On A Centerpin Reel

How much line goes on a Centerpin reel depends on the reel. Some reels have different size diameters and hold more or less line.

This picture shows one of my guide reels that is just slightly below the full amount. You can see the gap between the spool and the base is a little over an 1/8 of an inch to the line.

The first thing you want to do is fill the Centerpin reel about halfway with a fly line backing. Then add the mainline to about 1/8 inch from the inside gap of the spool and the base of the reel.

Depending on your reel this will be about 200 yards of backing and about 200 yards of mainline. See the backing that I prefer to use below.

The backing I use is the Cortland backing from FishUSA.com

Best Float Fishing Lines

Guides Top Choice

Raven Main Line

The Raven Main Line is made by a company that specializes in Centerpin fishing and this line is actually made for float fishing. This line has been my preferred line for the last 12 years and it is by far my favorite float fishing line to use.

The Raven Mainline floats well, has a thin diameter, and comes off the reel easily with minimal line twist. The line casts great which makes it a good line for anglers that are learning to Centerpin fish but it’s also great for more advanced anglers.

The Raven Main Line is also much cheaper than most other similar lines considering the spool size is 985 yards for less than $13.00 at some stores. Most other brands are less than 350 yards for almost the same price or more.

I have tested this line in all weather conditions, even in weather as low as 7f / -14c degrees and it held up very well. I have also had the same line on my reels for 4 years before I needed to change the line and that says something considering that my Centerpin reels get a lot more use than the average anglers Centerpin reel would.

I have also used this on spinning reels when float fishing and it worked great for me with no issues.

Popular Choice

Sufix Elite Line

Sufix Elite is a Premium Monofilament Line that many Centerpin and spin fishing float anglers use and like.

It has good strength, good handling, and durability. It also has three good colors to choose from.

Long Time Favorite

Sunline Line Fine Float ll

Sunline has been a favorite of many float fishing anglers for a long time. This upgraded version uses a special technology that really helps it float which is a big reason why many good Centerpin anglers use it.

P-Ion technology gives the floating line slickness, water repellency, color, and hydrophilic properties.

It has good strength, good handling, and durability. It also has three good colors to choose from.

Good Choice

Blood Run Main Line

This is another company that specializes in making Centerpin and float fishing products and they have a mainline that works well on Centerpin Reels.

Some of my clients have had good success using this line on a Centerpin reel if they use the 8-pound or 10-pound line sizes. It floats well and casts nice and is a good choice for Centerpin fishing.

Best Low Stretch Copolymer

Sufix Advanced Copolymer

There are some benefits to copolymer lines like a low stretch, better abrasion resistance, and better knot strength. This line is also still supple and casts nice and would be a good choice for those guys that like to use copolymer lines.

Backing For Centerpin Reels

If you’re setting up your Centerpin reel for the first time you will need backing to fill the bottom of the spool. Generally, about 200 yards of backing and about 200 yards of mono around 8lb should fill up your Centerpin reel nicely.

Backing For Centerpin Reels

This is the backing that I use to fill about half the spool of the Centerpin reel before I add the main Line.

Is Braided Line Good For Float Fishing?

Braided line is good for float fishing because it’s buoyant, it is very thin, it’s strong and abrasion-resistant, and it has little to no stretch which is great when setting the hook at a long distance.

The primary advantage to using braided lines when float fishing is that it is very strong while still being very thin.

Another great advantage of using braided lines for float fishing is that it’s the best line I have ever used when setting the hook on a float that is 100 feet or more down the river because the line doesn’t stretch and that gives you a solid hookset.

Braid does have a few disadvantages.

The downside to using braided lines and why I don’t recommend braided lines when float fishing is because anglers tend to break off more fish on the hookset when in close simply because it has no stretch to cushion the hook set. I find it’s even worse when guys use shorter stiffer rods that have less flex than the longer whippier rods.

To prevent this you need to either set softer when the float is close to you, which is hard to do in the excitement of your float dropping down fast, or you need to upsize your leader to a stronger and thicker leader.

The problem with upsizing your leader is that the fish might see it and then not eat your bait.

I have found that some anglers will break more fish off during the fight for the same reason.

The other problem anglers have when using the braided line is that it will freeze solid if it gets wet when winter fishing, especially if you submerge your reel for some reason. Once it freezes sold you will have problems with your drifts all day.

Some braided lines that I have used also tend to absorb more water which can make them sink which is not good for hook sets and for the presentation of your bait. A line that absorbs water is more likely to freeze or it will cause more ice build-up on the rod guides when fishing in below-freezing temperatures.

I have an article on how to keep the guides from freezing if this is ever an issue for you.

Use Float Fishing Lines That Experts Use

Whatever line you use for float fishing make sure you use one that has been used and tested by other anglers that actually know what they are doing. I have a lot of buddies and I know other guides that all float fish and they all tend to use these same lines and you should too.


  1. Hi Graham,
    Thanks for taking the time to write such informative posts, I have started fishing for Salmon and steelhead last fall and learn’t a lot form your site.
    I had a question regarding choosing fishing lines,I have been using Raven 8lb as per your recommendation .
    After reading a few reviews I realized that a lot of people claim that the Siglon ff2 floats higher and is more hydrophobic than raven line and is more supple(less memory/coils & twists).
    I wanted to know if this was true in your experience?(I don’t mind the extra $ for Siglon)

    1. I have used both lines and didn’t find a significant difference between the two, or should I say I didn’t find that the Siglon worked any better. The Raven line works and I have caught thousands of steelhead with it with no issues even at long distances and with lots of line on the water.
      With many fishing products, you will have fans of one product over another, and what some guys like others won’t like. In many cases, I think it’s more of a personal preference than anything. The only way for you to tell which you prefer is to try both, or if you already have Raven on the reel and it works perfectly for you just stick with it.

      Good Luck
