Choosing a fly line for your rod, your water, your fish.
The right line transforms a rod. The wrong one makes even a great rod feel dead. Start with your rod's action, then narrow by what you're fishing for. That's the order we work through it at the shop counter.
First time buying a fly line?
Here's the short version: pick a line that matches the number on your rod (a 5-weight rod takes a 5-weight line), and roughly the type of fishing you do most. If you don't know more than that, the line below is the right answer for most anglers. Two alternatives are listed for common situations where a different line is the better call.
The line we sell more of than any other. Long head, smooth coating, fits most modern rods. Buy it, fish it, you won't regret it.
The American classic. If you have an older or traditional-feeling rod — anything that bends easily when you cast — the 444 is the right answer and you'll save thirty bucks. Lays out dries beautifully.

If you have a newer, stiffer rod that doesn't seem to load right with a regular line, this is the upgrade. Built half-size heavy so the rod has something to bend against. Casts everything from dries to small streamers.

Three questions. Tailored to your rod and how you fish.
What are you fishing for?
What style of fishing?
What weight is your rod?
Look above the cork grip — it says something like "5wt" or "8 weight."
How does your rod feel?

Spey lines are rod-specific — two rods of the same weight can want grain weights 50+ apart. We use the Scientific Anglers spey chart (1,194 rods, 23 manufacturers) to give you a real recommendation, not a guess.
Is your old line actually done?
Most fly lines have 200–300 quality fishing days in them. After that, the taper and coating quietly fall off whether the line looks bad or not. Here's what to look for.
Rod action drives the taper and grain weight.
The action of your rod — slow, medium-fast, or fast — tells you whether to fish a true-to-weight line, a half-size heavy, or a full-size heavy. Get this part right and the rest of the choice falls into place.

Rod action sets the weight. Fishing type sets the taper.
Same 5-weight rod, three different fishing situations, three different lines. Here's how to think about each one. Recommendations link to in-stock products.
The most-fished category at the shop. Slightly more power up front than a pure dry-fly line, but presentable enough for a #16 PMD. Handles two flies, a small indicator, and a tippet ring without piling up.
Long head, long front taper, true-to-weight. You want delicacy on the cast and the ability to mend at 40 ft without disturbing the seam you're fishing.
Short, aggressive front taper. Half-size or full-size heavy. The line needs to turn over a thingamabobber, two flies, and shot without piling — true-to-weight lines just won't.
A dedicated thin-diameter mono-core comp line. Standard fly lines won't sink through the column or transmit takes the way a euro setup needs — and the diameter matters as much as the weight.
An overweighted front taper that turns big flies over without false-casting six times. Floating version keeps you on top for visible eats and dead drift work.
Sink tip for 2–6 ft down. Type 6 or full sinking when fish are 8+ ft down or you're swinging through fast water. The Cortland Galloup-collab lines are the most refined streamer-specific lines on the market right now.
A short-headed line built to load inside 20 ft. Most trout lines are designed for 25–50 ft casts; small water needs a line that's working as soon as you flick it off the tip-top.
A dedicated stillwater floater has a longer rear taper to suspend an indicator from distance and enough mass up front for chironomid leaders rigged 12+ feet deep.
If you only own one stillwater line, make it a clear intermediate. It slips below the wind chop and into the column where the fish actually are. Pair it with a sinking line for deeper water.
You need a line that turns over wind-resistant deer-hair bugs and poppers without false-casting six times. Short, aggressive front taper. Full-size heavy on a 6 or 7 weight rod.
Compact head, heavy front-end mass, low-stretch core. Pike and musky lines exist to turn over flies that weigh more than your tippet spool. A trout line will not do this job. Don't try.
Carp fishing rewards a flats-style line on a 6 or 7 weight. Short head for quick loads at 25 ft, supple coating, stealthy color. Don't use a tropical-coated line for cool-morning carp. It will stiffen up like wire.
The Magnum Glow is a specialty line. Half-size heavy aggressive taper with a glow tip you charge with a headlamp. Lets you see your line in pitch dark without spooking fish. Worth owning if you fish nights for big browns.
Long head, long back taper for accurate presentations to spotted fish. Tropical coating that stays supple in 90° heat and resists salt buildup. The new Magnitude clear-tip lines are worth a hard look for pressured fish.
Shorter, more aggressive front taper than a bonefish line — you want to turn over a heavy crab or spoon fly with one false cast. Louisiana redfish fishing especially rewards lines built for quick, close-in shots from the bow.
Low-stretch core for solid hooksets at distance. Front-end mass to deliver heavy crab patterns into wind. Quiet entry — permit spook off a noisy line splash from 30 ft. Purpose-built lines pay off here.
Compact head, hard tropical coating, low-stretch core for crushing hooksets through a tarpon's bony mouth. Most tarpon lines are full-size heavy by design — you're loading a fast 12 wt with the line up and out, not at 25 ft.
Heaviest grain windows, hardest tropical coatings, the most aggressive front tapers in the game. 12+ wt lines built to throw 8" baitfish patterns into 25 mph wind. Get the right line or you're casting all day for nothing.
Heading to Belize without knowing yet whether you'll get more bonefish, tarpon, or jack shots? A Grand Slam-class line is your single best answer. Built specifically to handle the bonefish-permit-tarpon trifecta on the same trip — multi-species versatility without specializing for any one. Tropical coating, balanced head, low-stretch core.
Short, powerful heads built to turn over sink tips and weighted flies. Compact head + appropriate MOW tip + running line. Integrated lines (head + running line in one) keep setup simple; shooting heads give you flexibility to swap.
Longer head, softer presentation, for unweighted or lightly-weighted flies on the swing. The Scandi counterpoint to Skagit — built for dries and wets on a tight line without disturbing the water.
The lines we put on the most reels.
We spool hundreds of reels every season. These are the lines we recommend most when someone hands us a rod and asks "what should I run on this?"
