Additionally, the Orvis Hydros comes with a heavy head that allows the tip to sink quickly, allowing you to lure in trout that lurk near the surface.

The line has an olive peach color with a 5 weight construction. This makes it suitable for most beginners. However, it doesn’t come in options that suit heavier rods.

The secret behind that is the weight-forward design of the fly line, which allows anyone to cast the line as far as possible.

It comes in a wide range of weight options, ranging from 3 to 8 weight, so it’s more suited for first-timers who use a relatively lightweight rod.

As one of the biggest competitors to Rio, Orvis also has another series of lines that are specifically made for trout.

Thanks to this design, the Orvis pro has become a golden standard for any angler who prefers dry fly fishing. 

Similar to the top-line options available from Rio, this one also has a gradient color pattern that will help you indicate the distance of the line and enhance your level of consistency on every cast.

  • The welded loop makes it incredibly easy to attach a leader to the line

Things to Keep in Mind While Shopping for a Fly Line for Trout


Buying the right fly line is always a bit tricky because you don’t know what exactly to look for, let alone buying a suitable one for trout.

To help you with this confusing task, we’ll briefly explain all the essential aspects that you should keep in mind while shopping for fly lines.

Line Weight

One of the simplest yet most important aspects of a fly line is the weight of the line. However, the weight of the line describes the size and thickness of the line more than it describes its actual weight.

This measurement is extremely important because if you get a line that is too light, it may not cast well or not cast at all. On the other hand, a heavy line weight might overstress or even break your rod.

Ideally, the market of fly lines offers various weights that range from 1 weight to 12 weight. However, the easiest and most reliable way to get the right size for you is to match the fly line weight with your rod.

To do that, all you have to do is check the bottom of the rod. There, you should find a number that indicates the weight of the rod. 

For example, if you have a 6 weight rod, a good rule of thumb here is to get a 6 weight fly line, and so on.

However, you should keep in mind that this isn’t necessarily the case for all rods, as some of them are designed to work with a huge variety of line weights.

Line Type

In addition to weight, fly lines also come in various types. Each one of these types depends on the type of fly you’re going to use.

Author Note: It’s important to pick a suitable line type for you because some of them are more suitable for specific varieties of trout than others. These types include:

Sinking Line

In this type, the entire fly line will sink underwater. This type is great for fly fishing in deep water, making it one of the best for trout that hang deep in lakes and ponds.

Floating Line

These ones float entirely at surface level, this one is great for fishing with streamers and nymphs in shallow water. This one is great for beginners because it’s quite easy to control.

Sink-Tip Line

A good combination of both where the tip sinks and the rest of the line floats. This one is great for fly fishing in rivers where you might need a little more control while getting relatively deeper than floating lines.

Tip Style

Another thing that you should keep in mind is that the tip of the fly line also comes in a wide range of styles that will have a huge impact on your performance.

For that reason, you have to understand what each one of these types has got to offer in order to pick the ideal one for you. Let’s have a quick look at each one of them:

Weight Forward Lines

These types of lines come with a tapered tip at the front part of the line. The main purpose of distributing the weight towards the front is to push the line’s center of gravity forward, and therefore, increase the speed of the line after casting so that it can travel further with less effort.

This makes it ideal for beginners and those who fish in wide bodies of water that require casting at a long distance.

Double Taper Line

These lines are pretty similar to a standard line in most properties except that they have two tapers at each end of the line instead of one. 

In addition to giving you more value for money, these lines are quite stable at a medium distance and can be a more suitable alternative for those who find it difficult to control weight forward lines.


In fishing lines, high memory means that the line has a very high tendency to revert back to how it was kept on a reel. This means that it’ll start to curl up while fishing, which limits your control over the line 

For that reason, you always need to avoid fly lines with memory problems because they’ll needlessly require a lot more effort to control in the water.


The color of a fly line is more valuable than just being an element of aesthetics. Of course, the color itself can vary according to your personal preference. 

However, many fly lines these days use colors to indicate distance, which allows you to figure out the distance that you can cast.


Fly lines are made from different materials, and therefore, they have different styles of finishes.

One of the most common materials used is Polyvinyl chloride (PVC), which offers a slick finish that protects the line from snapping.

In addition to PVC, polyurethane (PU) is also used, which is also slick but more durable and abrasion-resistant.


Fisherman with fishing rod

How long should the leader be when I’m fishing for trout?

In addition to the fly line, you should also consider your leader and its length while fishing for trout. Ideally, the length of a leader relies on two aspects.

The first one is the depth of the trout in the water. For instance, if you’re fishing for the trout in deep water, you need a pretty long leader to reach the fish. 

However, if the fish is feeding in a relatively shallow stream, you should keep the lead at a limited length. In most cases, the leader length should exceed the rod’s length.

In addition to the depth of the fish, your experience plays a huge role in choosing the length of the leader. 

This is because the longer your leader, the more difficult it will be to cast the line. If you’re a beginner, a 5 ft leader is a good starting point that you can work your way up from.

How do you properly cast a line while fly fishing for trout?

Fly fishing is all about the casting technique, so here’s a simple guide that will help you cast your line properly to catch trout:

  1. Hold the rod with a solid grip by placing your thumb over the rod while wrapping the rest of your fingers beneath the rod to support it.
  2. Initiate your backcast by extending your rod in front of you then pulling the rod backward with enough force to get your casting line behind you. Make sure that you start at a slow and steady pace and increase your speed as the rod travels further back.
  3. Once your line picks up the speed, you should stop exerting more pulling force and let the line’s momentum pull it further back. This also gives you a necessary fraction of a second to prepare for your forward cast.
  4. Keep your eyes and body oriented toward the area where you want the line to land, then stroke the rod in this direction in a quick motion that aligns with the line’s speed.
  5. Once the line picks up the forward pace, stop your hands and let the momentum of the line take it where you want it to land.

Such a technique requires a lot of training as well as trial and error in order to learn to transfer your energy into the line, so it’s perfectly okay if you can’t master it from the first try. 

However, with time, you’ll know the right time to let the line’s momentum carry on exactly where you want it to land.

Final Verdict

This wraps it up for today’s guide about the best fly line for trout fishing. As you can see, the market offers a wide variety of options that might seem pretty overwhelming if you don’t know exactly what you’re looking for. 

However, with this guide, you should be able to put your hand on the most suitable fly line for your needs. 

While there are some incredible options to choose from, we believe that the Rio Elite Gold Slick Cast Fly Line is the best overall option for anyone who’s looking for the maximum level of quality and performance while trout fly fishing.

However, if you’re on a strict budget and looking for a more affordable alternative that still works, we recommend the Scientific Anglers Air Cel Floating Trout Fly Lines.

In addition to being one of the most inexpensive options out there, the fly line will also do the trick for most anglers out there who don’t mind looping the line on their own.

Happy Hunting!
