Quick answer: For most anglers the best monofilament is a good all-round copolymer line in 6–12 lb — forgiving, cheap to respool, and easy to knot. Choose a low-memory copolymer if you want smoother casts, a high-abrasion mono around structure, and a clear low-vis mono in gin-clear water. Braid still wins for deep sensitivity, but mono remains the smartest first spool and the better choice anywhere you want stretch and shock absorption.
Monofilament is the line most of us learned to fish with, and despite the rise of braid it is still the right answer more often than the internet suggests. It stretches, which forgives a heavy-handed hookset and cushions a lunging fish at the boat. It floats, which suits topwater and float work. It is cheap, ties easily, and is close to invisible once you match it to the water. For a huge range of everyday fishing, a fresh spool of mono is all you need.
The catch is that “monofilament” spans everything from bargain-bin bulk spools to premium copolymers engineered for low stretch and high abrasion resistance. Picking well means understanding a few properties rather than chasing the flashiest label. Below we cover how to choose, then the main types of mono and where each one shines.
Quick Picks
- Best overall: an all-round copolymer mono in a mid-range breaking strain.
- Best for casting distance: a low-memory, supple copolymer.
- Best around structure: a high-abrasion mono that shrugs off rub and grit.
- Best in clear water: a clear or low-vis mono the fish struggle to see.
- Best budget option: a big bulk spool for filling reels and backing.
How to Choose Monofilament Fishing Line
Start with breaking strain, and be honest about the fish you actually target. Lighter line (4–8 lb) casts light lures further and gets more bites in clear water; heavier line (10–20 lb) buys insurance around structure and bigger fish. Most anglers over-gun their line and pay for it in casting distance and bite rate, so pick the lightest strain you can confidently land your usual fish on.
After strain, weigh up the properties that separate cheap mono from good mono. Stretch is a double-edged sword: it forgives mistakes and absorbs shock, but too much of it dulls bite detection at range. Memory — the tendency of line to hold the coils of the spool — causes tangles and kills casting distance, so a supple, low-memory line is worth paying for. Abrasion resistance matters anywhere your line rubs rock, timber or reef. Diameter counts too: a thinner line of the same strain casts better and is harder for fish to see, but check the manufacturer’s diameter rather than trusting the label strain alone. Finally, match colour to water — clear for clean water, and a low-vis tint where it helps you watch the line without spooking fish. Fresh line matters more than any of this: mono ages, so respool regularly.

All-Round Copolymer Mono
If you buy one spool, make it a quality all-round copolymer in the strain that suits your usual fishing. Copolymers blend materials to balance the classic mono trade-offs — reasonable stretch, decent abrasion resistance, manageable memory and good knot strength — so nothing lets you down badly. It is the line I would put on a beginner’s reel and on plenty of experienced anglers’ reels too. For bread-and-butter species like bream, whiting and flathead, it is hard to beat on value. Have a quick look at the current and most recent options on Amazon for the copolymer fishing line.
Low-Memory Casting Mono
When casting distance and a tangle-free spool matter most — light lure work, long casts to spooky fish — a supple, low-memory mono is the upgrade. These lines lie flat off the spool instead of springing into coils, so they flow through the guides and reduce wind knots. You trade a little toughness for that suppleness, so it is not the pick for dragging fish out of heavy cover, but for open-water casting it feels a class above cheap line. Have a quick look at the current and most recent options on Amazon for the low-memory monofilament line.
High-Abrasion Mono
Fishing around reef, rock, oyster racks or timber chews through ordinary line. A high-abrasion mono uses a tougher outer surface to survive the rubbing and grit that would nick and part a softer line. It tends to be a touch stiffer and higher in diameter for its strain, which is a fair trade when the alternative is a bust-off on the first run. If your favourite spot is snaggy, this is the line that saves fish and lures. Have a quick look at the current and most recent options on Amazon for the abrasion-resistant monofilament.
Clear and Low-Vis Mono
In clear water, line visibility can be the difference between a follow and a hook-up. A clear or low-vis mono is refined to disappear against the water, which matters most for finicky, pressured fish. Some anglers prefer a faint tint they can see against the sky while the fish cannot see it below the surface — a useful compromise for watching for subtle bites. Reserve the ultra-clear lines for your clearest days and lightest presentations. Have a quick look at the current and most recent options on Amazon for the clear monofilament line.
Budget Bulk Spool Mono
Bulk spools are the unsung heroes of a well-run tackle shelf. A large-capacity spool of dependable mono costs little per metre, which means you can respool often — the single best thing you can do for your fishing — without wincing at the price. It is also ideal as braid backing to fill a reel and stop braid slipping on the spool. It will not have the polish of a premium line, but for filling reels and staying fresh, cheap and plentiful wins.

Comparison
| Line type | Best for | Key strength | Trade-off |
|---|---|---|---|
| All-round copolymer | Everyday fishing | Balanced all-round performance | Master of none |
| Low-memory casting | Distance and light lures | Supple, tangle-resistant | Less abrasion resistance |
| High-abrasion | Reef, rock and timber | Survives rub and grit | Stiffer, thicker for strain |
| Clear and low-vis | Clear-water, spooky fish | Hard for fish to see | Harder for you to see |
| Budget bulk spool | Respooling and backing | Cheap per metre | Less refined |
Frequently Asked Questions
Is monofilament better than braid?
Neither is universally better. Mono stretches, floats, ties easily and costs less, which suits topwater, float fishing and beginners; braid is thinner and near stretch-free for deep, sensitive work. Many anglers use mono as a main line or as a leader off braid.
How often should I change my mono?
More often than most people do. Mono weakens with sun, heat and use, so respool at least once or twice a season if you fish regularly, and sooner if the line looks dull, feels rough, or holds heavy memory coils.
What breaking strain should a beginner start with?
A 6–10 lb all-round mono handles most common species and forgives learning knots and hooksets. Drop lighter for clear water and small fish; go heavier only if you are targeting bigger fish or fishing around structure.
Can I use monofilament as a leader?
Yes. Mono leader is supple, cheap and knots easily, and its stretch cushions a strike. Where fish are leader-shy in very clear water, many anglers switch the leader to fluorocarbon while keeping mono as the main line.
The Bottom Line
Monofilament is not the old-fashioned compromise it is sometimes made out to be — it is the right line for a great deal of everyday fishing, and the smartest first spool you can buy. Get an all-round copolymer in a sensible strain, respool it often, and you will out-fish plenty of anglers running expensive braid they do not need. Add a low-memory line for casting, a high-abrasion line for structure, and a clear line for tough clear-water days as your fishing demands. The one mistake to avoid is running old, over-heavy line and blaming the fish.
