Best Fly Line Theory: Key Selection Criteria

best fly line for trout

Before going into more detail about each of the lines on the list, I will explain a bit of the theory behind what lines are used and why to help you make a more informed decision.

There used to be only two types of fly lines, but now, there are many different fly lines. As a result, it is quite possible that you get overwhelmed and simply give up on trying to find out the best fly line for you.

Based on Amazon Ratings

The main selection criterion that I used was the average rating out of 5 stars of each fly line on Amazon.

According to Axiomq.com, Amazon is one of the largest e-commerce websites in the entire world. As a result, I found this site a reliable place to know what other people have to say about the products. As you might have learned in high school, the larger the sample size, the more accurate the average. Meaning, the more reviews there are, the more accurate the average rating will be.

Based On Fishing Conditions

Other than that, each specific line suits some weather conditions and fishing spots more than others. Fly anglers love trout fishing, and they can do it with different setups. As a general rule, those with weight at the front are better for windy conditions or where you need to be really accurate such as when you are shooting for a specific point next to a bank.

These fly lines are made heavy at the front so that the wind doesn’t blow them off the course. There is also less delay from when you cast it and when it hits the water. You can use it even if you happen to be a beginner.

The different types of fly lines are:

  • Double Taper (DT) Fly Lines: These fly lines have longer heads to form long loops and delicate presentation.
  • Weight Forward Lines (WF): These fly lines have shorter and heavier heads. For this reason, beginners use them for more effortless casting and quick turnover. Moreover, the heavier heads are also good when fishing with streamers.
  • Shooting Heads: These fly lines are pretty easy to cast, specifically into the breeze.
  • Special Nymphing Lines: These are special types of fly lines for nymphing techniques. They have low diameters to get the nymphs where fish are faster.

Recommendation: For all the theories and a complete discussion, I recommend reading this article by FishUSA.com. It explains how they are made and other interesting facts about fly lines.

Here is the list of best fly lines for trout your ideal fly fishing spots, and to know whether they are suited for an experienced caster or the one who is a seasoned casting sniper yet. So without any delay, lets’ get on with it.

RIO Mainstream Trout Fly Line

An All-Around Good Line

Rio brand has been around for quite a while and is well respected in the fishing world because of its quality. Although this line works well for all-purpose use, it is also great for beginners.

The tip has a welded front loop and is very easy to swap leaders. That way, you don’t have to fiddle around for a long time trying to switch them out and end up missing a fish.

An average customer rating of 4.6/5 from over 80 individual reviews

Given its good rating and considerable number of reviews, I can honestly say that you won’t be disappointed with this fly line. It is also specifically designed for trout, so you won’t have to worry about whether it will work for trout or not.

On top of that, you can use it for other types of fish, like bass, crappie, and bluegill. Subsequently, you’ll have more cash in your pocket because you won’t have to buy a bunch of different lines.

It will also save you time as there is no need to go through the frustration of remembering which line is for which type of fish or even creating a complex system to organize all of your lines.


Overall, there seem minor complaints about the fly line.

Some customers have reported that the new softer lines are harder to cast, especially when you compare them to the more previous lines that were more rigid.

They also mentioned that it creates a loud whirring sound (slightly more than usual) when you get a fish on.

Others haven’t had any issue with it.

RIO Intouch Gold Fly Line

Rio InTouch Gold Floating Fly Line Moss/Grey/Gold - Fawcetts Online

All-Purpose Fly Line for Trout

If you keep switching between different fly line styles and techniques, you must be tired of it and looking for a fly line that performs all tasks equally well. Thankfully, you can expect all that from Rio Intouch Trout Gold.

An average customer rating of 4.8/5 from over 80 individual reviews

Based on the reviews, it is pretty clear that you won’t regret buying it for a fantastic fishing experience. As it is made explicitly for trout, please don’t bother wasting your time anticipating whether it will work for trout or not.

Rio’s claim of an all-purpose fly line sits accurately on this fly line without any argument. If you have worked with Standard Rio gold, you can think of Rio Intouch trout Gold as an upgraded version.

The good thing is that tape is the same as Standard gold, so it loads the rod easily, maintains the loop stability when casting, and heads shoot the line with minimal effort.

With a 47-feet head section of the line, you can quickly mend the fly line at longer distances to make the drift-free fly floating.

The main difference between the standard and the upgraded version is that later is built with ConnectCore Rio’s proprietary core material with the quality of ultra-low stretch. The low stretch quality makes it more sensitive in your hand. So you can better estimate the fly in the water and delicate bites. This low line stretch gives more undeviating power for setting the hook, and the fish doesn’t get enough time to run.

Use of AgentX in the fly line coating bonds the two separate layers to boost the line’s performance. The Rio’s MaxCast hydrophobic line coating repels the water that allows the higher floating and farther shooting. The Maxfloat tip keeps the tip from sinking and helps it float twice as high as the normal tips.

If you got this fly line, don’t forget to take care of it for more prolonged use.

An average customer rating of 4.7/5 from 74 individual reviews

With a big sample size, it can be confirmed that the Avid Trout Fly line can be the best purchase for you.

This Rio fly line, specifically made for trout, has interesting technology to make your fishing experience new and enjoyable. Many anglers love the Avid Trout Fly Line for its features.

The overall length of the fly line is 80-feet, with welded loops at the front end. Its upbeat technology allows easy loading and is excellent for nymphing and streaming.

It would be completely right to say that it is an exceptional RIO product designed with technologies that can upbeat all your previous fishing experiences.

The advanced AgentX coating adds up to the durability and slickness of the fly line that also improves its performance.

A finely molded welded loop at the front allows the most uncomplicated leader attachment in no time. The smooth and expediting energy transfer from line to the leader results in a significant turnover. This makes rigging relatively easier and is the one reason for being preferred by many anglers.

It has a shorter head length that gives reasonable control on the rod while loading. It works best when you use a modern or fast action rod. So, with minimal energy, you can cast with this fly line.


Serious cons are not as evident for this product. Only minor things were reported in the reviews.

The customers didn’t like the brighter color of the line, and some find it awkward while casting nymph rigs at a shorter distance.

Another complaint noted was the weird coils at the front section that was not easy to straighten out. Although it worked well for streaming and nymphing, it wasn’t going well for dry fishing.

Talking about the product’s longevity, most were of the view that they can’t say much as only a few weeks have passed since they bought it.
