Spey & Swing Rig
Two-Hand Rod — Skagit & Scandi
The most addictive way to catch a steelhead. A long rod, a flowing cast, and a fly swinging through the current. Two line systems, one obsession.

Spey Rod
A Spey rod is a two-handed fly rod designed for river casting. The extra length gives you leverage to cast heavy lines without a back cast — essential on rivers with trees and banks behind you.
- Length: 12'6" to 13'6". 13' is the sweet spot for Great Lakes steelhead. Switch rods (11') work for smaller rivers.
- Weight: 7 or 8. 7-weight for Scandi and lighter presentations. 8-weight for Skagit and big flies. If buying one rod, go 7wt — it handles both systems.
- Action: Medium to Medium-Fast. You need the rod to load deep for Spey casts. Ultra-fast rods fight you on sustained anchor casts.
Reel
A Spey reel needs to balance a 13' rod, hold 100+ yards of backing plus a bulky head system, and have a drag that can handle a steelhead running downstream in heavy current.
- Size: 7-9 weight rated. Needs to hold the running line + head + backing. A 7/8 reel for a 7wt rod, 8/9 for an 8wt.
- Large arbor. Faster line retrieval, less memory coils, better drag consistency.
- Sealed drag. You'll be fishing cold, wet conditions. A sealed drag keeps grit and ice out.
Choose Your Line System
This is the fork in the road. Same rod, same reel — but the line system defines your entire approach. Pick one, and everything downstream changes.
The Line System
Every connection matters. Here's how it all links together — and which knot to use at each joint.
Backing
Backing fills the reel and provides insurance when a steelhead makes a long run. You'll rarely see it, but when you do, you'll be glad it's there.
- Dacron (20-30 lb): The standard. Affordable, low-stretch, easy to handle. 150-200 yards is plenty. Most anglers use this.
- Gel spun (30-50 lb): Thinner diameter = more capacity on the reel. Stronger for the same thickness. Worth it if you're chasing big fish or need room for a bulky Skagit head.
Running Line
The running line sits on your reel and shoots through the guides during the cast. It connects to the head via a loop-to-loop connection. Think of it as the thin, slick line that lets your head fly.
- Mono running line (25-30 lb): Cheapest, shoots farthest, tangles most. Amnesia or Maxima Chameleon. The budget choice that works.
- Coated running line: Thicker, less tangly, easier to handle in cold. Rio ConnectCore, Airflo Ridge. Best all-around.
A Skagit head is a short, heavy, compact shooting head (18-24 feet) designed to turn over sink tips and big flies with minimal casting stroke. It's the brute-force approach — and it works beautifully.
- 7wt rod: 425-500 grain head
- 8wt rod: 500-575 grain head
- Rule of thumb: Rod grain window is usually printed on the rod blank above the grip. Start in the middle of the range.
A Scandi head is a longer, lighter, more aerodynamic shooting head (30-40 feet) designed for smooth, continuous-motion casts. It carries smaller flies elegantly and presents them with less disturbance.
- 7wt rod: 350-425 grain head
- 8wt rod: 400-475 grain head
- Key difference: Scandi heads are lighter than Skagit for the same rod — they rely on line speed, not mass.
Sink tips are short (10-15'), heavy sections of sinking line that connect between your Skagit head and your leader. They get your fly down to where the fish are. The "T" rating tells you how fast it sinks.
- T-8 (light): Slow sink. Shallow runs, low water, warmer months. 6-8 inches per second.
- T-11 (medium): The everyday tip. Moderate depth, normal flows. Start here.
- T-14 (heavy): Fast sink. Deep runs, high water, winter. Gets down fast in heavy current.
Polyleaders are tapered, coated leaders that replace sink tips in a Scandi system. They're lighter, cast more elegantly, and come in a range of sink rates from floating to fast-sink.
- Floating: Surface presentations, skating flies, summer.
- Intermediate: Just below the surface. The most versatile choice.
- Fast sink: Deeper presentations when needed. Not as deep as T-tips but smoother to cast.
Leader
Short and heavy. Skagit leaders are 3-5 feet of straight fluorocarbon, 10-15 lb. The sink tip is already doing the depth work — the leader just needs to turn the fly over and be strong enough to handle steelhead.
Longer and lighter. Scandi leaders are 6-12 feet, tapered or straight fluorocarbon, 8-12 lb. The longer leader gives a more natural presentation — the fly arrives before the line.
The Fly
Skagit flies are big, heavy, and designed to push water. The heavy head and sink tip can turn over flies that would be impossible on lighter systems.
- Intruders (black/blue, pink/orange)
- String Leeches
- Egg Sucking Leeches
- Articulated streamers
- Woolly Buggers (size 2-6)
- Singles: #2 to #2/0
- Shanks: 25-35mm articulated
- Barbless preferred (ethically and legally in some waters)
Scandi flies are smaller, lighter, and more elegant. The lighter head can't turn over heavy flies — but it doesn't need to. These patterns work on the swing with subtle movement.
- Soft hackle wet flies
- Spey flies (Lady Caroline, Green Butt Skunk)
- Small intruders (sparse)
- Muddler Minnows
- Singles: #4 to #8
- Light wire hooks
- Up-eye or down-eye traditional
Casting Basics
The workhorse. Works on either bank. Two sweeping motions set the anchor, then fire. Learn this first.
Read the full guide →Faster, one sweep. Best when the current is on your casting-hand side. Elegant when it clicks.
Read the full guide →For when the current is wrong for a single Spey. Lifts and repositions the anchor with a downstream snap. Essential for fishing both banks.
Swinging flies guide →Reading the Water for the Swing
- Classic swing water: 3-6 feet deep, walking-speed current, gravel or cobble bottom. The fly sweeps broadside across the current — irresistible to holding fish.
- Tailouts: Where a pool shallows out before the next riffle. Fish stack here. Cast across, let it swing through the entire tailout.
- Inside seams: Where fast water meets slow on the inside of a bend. Fish hold on the soft side, watching the fast water for food.
- Step and cast: One cast, two steps downstream, repeat. Cover water methodically. The grab comes when you least expect it.
| Condition | Skagit | Scandi |
|---|---|---|
| High/stained water | Best — heavy tips get down | Struggles to reach fish |
| Low/clear water | Too aggressive | Best — subtle presentation |
| Cold water (<38°F) | Best — fish are deep | OK with fast-sink poly |
| Summer/fall | Works for kings | Best — fish near surface |
| Tight quarters/trees | Better — shorter head | Needs more room |
Tie the weak links correctly
A clean fixed loop for leaders, fly line connections, and loop-to-loop rigging.
A fixed loop knot that lets streamers, jigs, and small plugs move instead of hanging stiffly from the line.
A classic line-to-line knot for backing, braid, mono, and diameter changes.
