Trout fishing is one of the most technical forms of fly fishing as there are so many different approaches required that your rods and lines have to keep up with. Some anglers compare it to saltwater fishing for bonefish but bonefish are a lot simpler than trout in my experience.

  • Taper: Weight Forward
  • Length: 90 ft
  • Color: Olive


  • Superslick coating for good shooting and floatation
  • Low stretch and sheds dirt and oils for longer-lasting performance
  • Easy for mending on the water and aerially
  • Perfect all-around trout line for nymphing, and dry fly.
  • Top-quality welded loops for easy leader attachment
  • Quite expensive

The Orvis Pro Trout floating fly line is hailed as one of the best floating fly lines around thanks to its new and improved design. Perfect for streamer fishing. Orvis has put a lot of work into their floating lines and their addition of a textured coating has made all the difference.

The textured coating gives the floating fly line better floatation so it sits higher in the water. This means the fly line is easier to see and manipulate as it less drag and friction on the water. Mending your fly line and picking it up to cast will be a lot easier and give off far less water spray for a subtler approach.

The long front shooting head on these fly lines makes loading your fly rod a piece of cake. You can feel the tip of your rod start to flex as soon as you lift the line and with a single back cast, you can push the shooting head into the running line with one false cast.

This means long distances and being able to cast larger flies into the wind with ease. The longer tapers at the tip of the fly line also make it perfect for small casts and accurate soft presentations at any distance.

Types Of Trout Fly Fishing Line

Types Of Trout Fly Fishing Line

To choose the best fly line for you, you’ll need to understand the types of fly fishing lines available for trout, and you have two main choices; weight forward and double tapered.

Weight Forward (WF)

A WF fly fishing line is thick and heavy at the front and tapers into the running line, creating a shooting head for pushing long distances with ease.

The heavier front end loads your rod quickly and with more energy for shooting a long cast with minimal back casts. It’s perfect for turning over larger flies, a heavy nymph, or when you fish into the wind and are always used in saltwater for this reason.

For more selection on fly line weights see the following reviews:

Double Tapered

A double tapered line has a front taper and a back taper without much of a running line. The major benefit of this is that you can flip the line around once it’s used and pretty much have a new fly line at the front end.

These types of lines are known to be more delicate when fishing light dries but in actual fact that comes down to whoever is holding the rod.

The one thing these fly lines do help with is making longer roll casts when you’re on wide water. The back end taper helps the line flow with less energy.

Which should you choose?

There is an age-old fly fisher debate about which line is better for what and a lot of fly fishing myths that come out of it. The fact is that both types of lines perform the same when cast to 45-50 feet, which is the length you’ll be casting for trout most of the time.

If you plan on casting heavy flies further than 50ft on the water, then a WF line is best. For anyone who wants to roll as far as possible and mend at distance, a double taper will suit you best.

What weight line should you have

What weight line should you have?

The line weight you choose should match your rod first, then your flies you’ll be fishing with, and have nothing to do with the fish.

To get the best casting performance out of your rod, whether you’re nymph fishing or fishing in saltwater, your line or lines have to match your rod.

Your rod weight will guide you to your line weight. As a general rule, you can fish one weight above or below or the same as your pole. So a 3 wt rod can work with a 2/3/4 wt line. You can down a weight for delicacy, up a weight for a bigger punch and distance, or when fishing into the wind.

Tapering Out

So which of our trout fly lines is the best? Well, this is technically for you to choose, as we anglers all fish differently, and prefer different lines for different rods. But, in case you want my opinion, here it is.

The best floating fly line for all types of fly fishing techniques for trout, from nymphing to large streamers, is the Orvis Pro Trout. This fly fishing line makes casting, mending, and accuracy as easy as possible so you can always guide your fly where you want it to be.

The runner-up is the Rio Intouch Trout LT. The fly line comes with a shooting head for all occasions that’ll let you drop a fly in front of a fish into a strong wind with ease. It has low memory, comes in every trout line weight, and the beautifully tapered head on these fly lines will let you drop a fly down immaculately.
