How to Choose the Best Fly Line for Steelhead

We've already talked about choosing the best fly rod for Steelhead and the best fly reel for Steelhead. These posts are important if you're a first-time Steelhead angler. They can also help anglers who are purchasing new gear determine which rods/reels fit their casting style and angling technique. And, to round out our species-centered blog posts about Steelhead, this post will help you choose the right fly line.

In our past Steelhead posts, we've covered single-handed rods/reels, switch rods/reels, and Spey rods/reels. This post covers fly lines for both: we'll start with single-handed lines, then get into the Skagit-versus-Scandi question for two-handed rods. The short video below is a quick primer:

In terms of single-hand lines, a lot of single-handed angling for Steelhead involves nymphing. You can also swing flies with a single-handed rod. In this post, we'll focus on streamer and nymph lines that pair well with single-handed rods.

THE BASICS

First, choose a fly line that matches your rod. If you're fishing a 10' 7wt fly rod, pair that rod with a 7wt fly line.

Steelhead fishing is done in cold water conditions. Therefore, choose a fly line that's built for cold water angling. A tropical line is going to shrivel up and give you major problems when you're fishing for Steelhead. If you're confused about which lines are made for cold water conditions, read our article about water temps here.

So we've narrowed down your choices. You should be considering a cold water fly line that matches your rod weight. And if you want to be safe, a fly line with 'Steelhead' or 'Nymphing' in the name is probably a good bet. If you're considering a RIO InTouch Salmon/Steelhead, Scientific Anglers Amplitude Anadro/Nymph Fly Line, or Cortland Salmon Steelhead Fly Line, you're on the right track.

But surely there are times when other lines would be more efficient and more productive.

FISHING TECHNIQUE

Fishing Technique is one of the most important considerations when choosing a fly line for Steelhead. Because these fish can be targeted in a variety of different ways, it's important to choose a line that matches your desired angling style. If you're swinging streamers with a single-handed rod, you're going to want a shooting-style line that allows you to cover the most water. If you're nymphing, your line is going to look totally different.

Nymphing Lines: SA Anadro is one of the best nymphing lines on the market. RIO InTouch Salmon/Steelhead line and the Cortland Salmon Steelhead line work well, too. These lines have short, aggressive heads and long back tapers to help anglers turn over bulky nymph/indicator rigs at longer distances. We recommend these lines when targeting Steelhead with nymphs in the Great Lakes or the western US/Alaska. We especially like the Amplitude (textured) version of the Anadro - it's one of the few lines that genuinely casts better textured than smooth.

Streamer Lines: If you're swinging flies with a single-handed rod, a few different lines are optimal. The RIO InTouch VersiTip II line system is a great option for anglers who want to be able to adjust their setup for differing water types. This interchangeable tip system helps anglers swing flies on a single-handed rod with efficiency and versatility. A variety of single-hand Spey lines will work well too if you're planning on single-hand Spey fishing. The RIO Single Hand Spey Elite line is one of our favorites.

Dry Fly Lines: Skating dries on a single-hander calls for something lighter with a long head, like the RIO Salmon/Steelhead. The long, light head lifts off the water easily for repeated pickups and recasts. It rewards a practiced caster and can feel tough at short range, so it isn't the first line we'd hand a beginner.

Two-Handed Lines: Skagit vs. Scandi

If you're fishing a spey or switch rod, the choice usually comes down to Skagit versus Scandi. Most two-handed steelheaders swing flies, and that's where a Skagit head shines: its short, heavy front loads the rod easily and turns over weighted flies and heavy sink tips without fuss. Every Skagit line is built to be fished with a tip, which makes it the go-to for the dark, deep days of winter. The RIO Skagit Max Power is a great all-around choice - honestly, there isn't a huge difference between brands here, so the bigger variable is head length.

On length: a shorter Skagit head (around 20 feet, roughly 450 grains) is easy to cast, gets down fast, and suits shorter rods like a switch rod or tight, bushy water. Longer rods in the 12.5- to 13-foot-plus range cast a longer head more comfortably. Need to get down even faster? A multi-density Skagit head like the RIO Skagit Max GameChanger sinks the front of the line quicker than an all-floating head.

A Scandi head, by contrast, is a full floater built for presentation. It's the better, more enjoyable choice for skating dries and fishing near the surface - we love a clean Scandi taper like the Gaelforce ESH - but it won't throw heavy flies or tips like a Skagit will. Multi-density Scandi lines exist, but they take real effort to cast and are best left to dedicated Scandi casters.

Whichever you choose, an interchangeable tip system is essential for swinging. We like OPST tips (they run a touch shorter) and MOW tips, both excellent for dialing in depth. And the most important rule applies to single- and two-handed alike: cast the line on your rod before you commit, because the right match is rod-specific.

LEADERS/TIPPET

Regardless of which technique you're using, these lines will help you be a more successful angler on the water this season. Plus, RIO makes a variety of tippets and leaders that will help your chances on the water, too. The RIO Fluoroflex Steelhead/Salmon Leader is a great choice when swinging flies and other Fluoroflex options like the Trouthunter Fluorocarbon Leader are ideal for nymphing. Similar tippets should be used.
