How We Test Carp Fishing Line
Every line here is scored on the same four things, so a budget mono and a fluorocarbon mainline can be weighed on equal terms. Strength comes first for me, because a mainline that parts on a fish is the one thing you can't afford.
For strength I look at the breaking strain for the diameter, knot strength and abrasion resistance over gravel and snags. Casting and handling covers how supple the line is, its stretch and memory and how smoothly it leaves the spool, while presentation is about how fast and flat it sinks and how well its colour blends in on the bottom.
Value for money then weighs all of that against the price and spool length, and the overall score is the average of the four. Fluoro and braid cost more per metre than mono, which shows in their value scores.
Which Carp Fishing Line Should You Buy?
| If you | Choose | Why | Watch out for |
|---|---|---|---|
| Want one mainline for most fishing | Shimano Technium | A three-layer build with 12 per cent stretch and high abrasion resistance | Not the fastest-sinking line |
| Cast a long way with a low-vis line | Fox Exocet Pro Low Vis Green | Super soft and supple, and made for distance | Less tough than the Subline |
| Want mono pinned to the bottom | Gardner GT-HD Low Vis Green | Fast sinking and settles flush to the lake bed | Starts at 12lb |
| Fish snags, weed or sharp gravel | Korda Subline | Ultra-tough, dense and sinking, yet still supple | Built for toughness over distance |
| Want to fill three reels from one spool | Trakker Mono Reel Line | 1000m of fast-sinking dark green mono | No 15lb option |
| Want a dependable all-round mono | Daiwa Sensor | Supple, knots superbly and comes on bulk spools | Not a low-vis carp line |
| Are filling reels on a tight budget | Korda Basix | Tough, abrasion-resistant line for very little | Thick for its strain |
| Want the line as hidden as possible | Korda Kontour | 100% fluoro, practically invisible and fast sinking | 200m spools |
| Want fluoro with spool markers | Thinking Anglers FTX | Pure fluoro, with markers on the 600m spool | Only 14lb and 16lb |
| Fish heavy weed with braid | Thinking Anglers SBX | A round, fast-sinking braid with zero stretch | Needs a leader, and check the rules |
| Want a braid for long range | Trakker Sinking Braid | An ultra-smooth finish made for distance casting | Needs a leader, and check the rules |
| Want a fine sinking braid for less | RidgeMonkey Descend | Low-diameter 20lb and 30lb that sink super fast | Stops at 30lb |
The Best Carp Fishing Lines We Have Reviewed
The following carp fishing lines achieved the highest scores across our four scoring categories, which are Strength and Abrasion, Casting and Handling, Presentation, and Value For Money. The overall score is the average of these four.
Mono | Fluorocarbon | Sinking Braid
Shimano Technium Line
Best Overall
How It Scored
High strength for its diameter and high abrasion resistance.
A supple middle layer and smooth outer skin for clean casting.
Sinks and stays dark, but not as fast as a fluoro.
Not the cheapest, but a quarter-pound spool goes a long way.
For me, the Technium is the mono most carp anglers could spool up with and stop worrying about. Its three-layer build pairs a hyper-resistant, low-stretch core with a supple middle layer and a smooth, UV-protective outer skin, so it casts well, knots well and stands up to abrasion.
Stretch is cut to 12 per cent, which helps bite indication and feel at range, and the strength for its diameter is high, with the 12lb at 0.32mm and the 15lb at 0.38mm. A quarter-pound spool holds 1,100m of 12lb or 790m of 15lb.
To be fair, it isn't the cheapest, and it doesn't sink as fast as a dedicated low-vis mono or a fluoro. As one dependable mainline for most carp fishing, though, I think it's the all-rounder to beat.
Pros
- ✓Three-layer build balances low stretch with a supple feel
- ✓Linear stretch cut to 12 per cent for clearer bite indication
- ✓High abrasion resistance and strength for its diameter
- ✓Smooth UV-protective outer layer reduces casting friction
- ✓Quarter-pound spools hold 790m to 1,920m depending on strain
Cons
- ✕Costs more than budget monos and bulk spools
- ✕Not as fast-sinking as a dedicated low-vis mono or fluoro
Fox Exocet Pro Low Vis Green
Top Low-Vis Mono
How It Scored
High abrasion resistance and good knot strength.
Super soft and supple, and made for distance.
Low-vis green and sinking.
1000m spools at a fair price.
The Exocet Pro is Fox's distance mono, and the Low Vis Green version blends in on most lake beds. It's super soft and supple, which helps it peel off the spool cleanly on a big cast, and it sinks rather than sitting up in the water.
It comes on 1000m spools from 10lb to 23lb, at 0.261mm to 0.400mm, with high abrasion resistance and good knot strength for a line this supple.
So, what's the catch? A soft, supple mono gives a little away on toughness next to a dedicated abrasion-resistant line like the Korda Subline. For distance work with a low-vis line, though, I think it's a great choice.
Pros
- ✓Fine diameters for the strain, from 0.261mm at 10lb
- ✓Super soft, supple feel should mean low memory on the reel
- ✓Made for distance casting, with low friction through the rings
- ✓High abrasion resistance and good knot strength for its diameter
- ✓Six breaking strains from 10lb to 23lb, all on 1,000m
Cons
- ✕Fine diameters leave less margin in really heavy snags
- ✕A sinking line, but not a dedicated fast-sinking one
Gardner GT-HD Low Vis Green
Superb Sinking Mono
How It Scored
High knot strength and abrasion resistance.
Reduced stretch with a smooth, supple finish.
Fast sinking and low-viz green, settling flush to the bottom.
A fair price for a dedicated sinking mono.
If you want a mono that sinks fast and lies flat, the GT-HD is the one I'd look at. It's a copolymer blend made to sink quickly and settle flush to the lake bed, and the Low Viz Green colour helps it disappear over silt and weed.
It comes in 12lb, 15lb and 18lb, at 0.33mm to 0.39mm, with reduced stretch, a crisp, responsive feel and a smooth, supple finish. Knot strength and abrasion resistance are both high.
To be fair, the range is narrower than some, with nothing under 12lb. For most carp fishing, though, I think it's a superb sinking mono.
Pros
- ✓Fast-sinking formulation settles flush to the lake bed
- ✓Low-Viz Green gives camouflage on both slack and tight lines
- ✓Reduced stretch improves feedback and bite indication at range
- ✓High knot strength and abrasion resistance from a copolymer blend
- ✓Large spools hold 1,150m of 12lb and 1,030m of 15lb
Cons
- ✕Only three strains, topping out at 18lb for heavy work
- ✕Crisp feel won't suit anglers who prefer a really soft mono
Korda Subline Ultra Tough Sinking Mono
Great for Snags and Weed
How It Scored
Ultra-tough, and made for snags, weed and gravel.
Supple, but built for toughness over distance.
A dense sinking formula in brown or green.
A fair price for a specialist tough line.
Subline is Korda's ultra-tough sinking mono, made for the hard stuff, from heavy weed and snags to abrasive gravel. A denser formula helps it sink, and it comes in brown or green to match the lake bed.
It's available from 10lb to 20lb, at 0.30mm to 0.43mm, on 1000m spools. Despite the toughness, it's supple rather than stiff or wiry, which helps it lie well and come off the spool cleanly.
The trade-off is that toughness comes first, so it scores a little lower for casting than a dedicated distance line like the Fox Exocet Pro. For snaggy, weedy waters, though, I think it's one of the safest bets you can make.
Pros
- ✓Built for heavy weed, snags and abrasive gravel
- ✓Dense formula helps the line sink and lie on the bottom
- ✓Supple without the stiff, wiry feel of many tough lines
- ✓Four strains from 10lb to 20lb, all on 1000m spools
- ✓Subtle brown or green colours to suit different lake beds
Cons
- ✕Thicker diameters for the strain cost some casting distance
- ✕Costs more than budget monos if you fish clean, open water
Trakker Mono Reel Line 1000m
Great Value Bulk Spool
How It Scored
High knot strength and an abrasion-resistant build.
Ultra-smooth and supple.
Dark green, fast sinking and low visibility.
One 1000m spool fills at least three reels.
Trakker's Mono Reel Line is a dark green, fast-sinking mono on 1000m spools, which is enough to fill at least three reels. It's ultra-smooth and low visibility, and it's supple enough to follow the contours of the lake bed.
It comes in 12lb, 18lb and 20lb, at 0.30mm to 0.40mm, with high knot strength and an abrasion-resistant build.
There's no 15lb in the range, so you'll be choosing between 12lb and 18lb. As a good-value bulk spool for filling a set of reels with sinking mono, though, I think it's hard to argue with.
Pros
- ✓1,000m spool fills at least three reels in one go
- ✓Fast-sinking and supple enough to follow lakebed contours
- ✓Dark green, low-visibility finish for discreet presentation
- ✓Ultra-smooth finish to help with casting distance
- ✓Fine 0.30mm diameter for the 12lb breaking strain
Cons
- ✕No specialist toughness for heavy weed or snags
- ✕Heavier strains are thicker than the finest distance monos
Daiwa Sensor Bulk Spool
Great All-Rounder
How It Scored
Rugged and durable, with a consistent diameter.
Supple, and casts smoothly.
Not a dedicated low-vis or fast-sinking carp line.
Bulk spools keep the cost per reel low.
Daiwa Sensor is one of the most versatile monos you can buy, with breaking strains from 4lb right up to 60lb on bulk or 300m spools. It's supple, has a consistent diameter, knots superbly and is built to be rugged and durable.
For carp, the 12lb and 15lb are the obvious choices, and a bulk spool goes a long way, which keeps the cost per reel low.
It isn't a dedicated low-vis or fast-sinking carp line, so presentation isn't its strong point. As a dependable, good-value mono for all-round use, though, I think it's great.
Pros
- ✓Huge range of breaking strains, from 4lb right up to 60lb
- ✓Supple, and keeps casting smoothly after long periods on the reel
- ✓Consistent diameter and superb knotting for dependable connections
- ✓Bulk spools give lots of line, with 1,325m of 10lb
- ✓Rugged, durable mono that suits carp, float and sea fishing
Cons
- ✕Not a dedicated low-vis or fast-sinking line for wary carp
- ✕Thicker for the strain than dedicated distance monos
Korda Basix Main Line
Best Budget
How It Scored
Tough and abrasion resistant, with good knot strength.
Casts well, but it's thick for its strain.
Camo green, but not a dedicated sinking line.
A very low price for a carp mainline.
Korda Basix is about as cheap as a decent carp mainline gets, and it still covers the basics. It's camo green, very abrasion resistant and tough, with good knot strength and relatively low stretch, and it casts well.
It comes in 12lb at 0.35mm and 15lb at 0.40mm, on 500m or 1000m spools.
To be fair, it's on the thick side for its breaking strain, so it won't cast as far as a finer line like the Technium. For beginners or anyone filling reels on a budget, though, I think it's great value.
Pros
- ✓Very low price for a branded carp mainline
- ✓The 500m spool suits smaller reels or filling just two
- ✓Camo green finish blends in with the lake bed
- ✓Tough and abrasion resistant, with good knot strength
- ✓Relatively low stretch helps you feel the lead down
Cons
- ✕Thick for its strain, with the 12lb at 0.35mm
- ✕Not a dedicated sinking line, so it may need back leads
Korda Kontour Fluorocarbon
Top Fluorocarbon Mainline
How It Scored
Highly abrasion resistant, with genuine knot strength.
Soft and peels smoothly, casting beyond 100 yards.
100% fluoro, practically invisible and fast sinking.
200m spools make it dear per reel.
If you want your mainline as hidden as it can be, Kontour is the one I'd start with. It's 100% fluorocarbon, practically invisible underwater and fast sinking, so it hugs the bottom rather than rising off the lead.
It's a soft line that peels smoothly from the spool and casts up to and beyond 100 yards. It comes in 12lb, 15lb and 18lb, at 0.33mm to 0.37mm, with high abrasion resistance and genuine knot strength.
The catch is spool length, as each spool is 200m, so filling three reels costs a lot more than with mono. For wary fish and clear water, though, I think it's well worth it.
Pros
- ✓Practically invisible underwater, so it suits pressured and clear waters
- ✓Fast sinking and dense, so it lies flush to the lake bed
- ✓Soft for a fluorocarbon and peels smoothly from the spool
- ✓Fine diameters, from 12lb at 0.33mm to 18lb at 0.37mm
- ✓Highly abrasion resistant, with genuine knot strength for a reliable connection
Cons
- ✕Only 200m per spool, so far dearer per metre than mono
- ✕Not quite as supple as a soft carp mono
Thinking Anglers FTX Fluorocarbon Mainline
Great Low-Vis Fluoro
How It Scored
Pure fluoro that doesn't absorb water or weaken under UV.
Reduced stretch, but fluoro is less supple than mono.
Pure fluorocarbon in a mist grey tint.
Dear per metre, even on the 600m spool.
FTX is Thinking Anglers' pure fluorocarbon mainline, in a mist grey tint made to blend in. It has reduced stretch, is unaffected by UV and doesn't absorb water, so it keeps its strength over time.
It comes in 14lb at 0.35mm and 16lb at 0.37mm, on 200m or 600m spools, and the 600m spool has markers at 200m, 300m and 400m, which helps when you're loading three reels.
The catch is cost, as it's one of the dearest mainlines per metre. For anglers who want the stealth of fluoro with a choice of spool size, though, I think it's a great option.
Pros
- ✓Mist grey tint cuts glare where weed holds the line up
- ✓Dense pure fluorocarbon that sinks well and settles unobtrusively
- ✓Reduced stretch gives crisp, positive bite indication
- ✓Unaffected by UV and doesn't absorb water, so it lasts
- ✓600m spool has markers at 200m, 300m and 400m
Cons
- ✕Dearest per metre, and far pricier than any bulk mono
- ✕Only 14lb and 16lb, slightly thicker for the strain than Kontour
Thinking Anglers SBX Sinking Braided Mainline
Top Sinking Braid
How It Scored
Zero stretch and high abrasion resistance at 25lb or 40lb.
Round profile, with fewer wind knots.
Fast-sinking fibres in a green and black finish.
Braid costs more per reel than mono.
SBX is a sinking braided mainline for anglers who fish weed or want direct contact at range. It's a tightly woven, round braid made from a fast-sinking blend of fibres, so it settles down rather than floating like an ordinary braid.
It comes in 25lb or 40lb, on 300m or 600m spools with removable markers on the 600m, and it has zero stretch, high abrasion resistance and fewer wind knots for easy casting.
As with any braid, there's no stretch to cushion a lunge under the rod tip, so you'll want a leader and a forgiving rod, and some waters ban braid, so check the rules. For weedy waters, though, I think it's top of the pile.
Pros
- ✓Extremely robust, tightly woven build with high abrasion resistance
- ✓Fast-sinking fibres settle the braid quickly onto the lake bed
- ✓Green and black camo pattern blends in on most waters
- ✓Zero stretch gives direct contact and clear bite indication
- ✓600m spool has removable markers for splitting across reels
Cons
- ✕Needs a leader, and some waters ban braided mainline
- ✕Zero stretch needs care to avoid hook pulls near the net
Trakker Sinking Braid Reel Line 300m
Great for Long Range
How It Scored
High knot strength and abrasion resistance.
An ultra-smooth finish made for distance casting.
Dark green and fast sinking.
300m spools cost more per reel than mono.
Trakker's Sinking Braid is a dark green braided mainline with an ultra-smooth finish made for distance casting. It's supple and fast sinking, with low stretch for better bite indication at range.
It comes in 30lb, 40lb, 60lb and 80lb, at 0.29mm to 0.49mm, on 300m spools, with high knot strength and abrasion resistance.
The heavier strains are a lot of line for most carp fishing, so most anglers will want the 30lb or 40lb. As with any braid, use a leader and check your water allows braid. For long-range fishing over weed, I think it's a great choice.
Pros
- ✓Ultra-smooth finish and supple build suit long-range casting
- ✓Slim diameters for the strain, with 40lb at just 0.33mm
- ✓Four strains from 30lb to 80lb cover most carp situations
- ✓Fast sinking, so it follows the contours of the lake bed
- ✓Low stretch gives sharp bite indication and feedback from the rig
Cons
- ✕Only 300m spools, so several reels need several spools
- ✕Needs a leader, and braid is banned on some waters
RidgeMonkey Descend Sinking Braid
Great Value Sinking Braid
How It Scored
Highly abrasion resistant, at 20lb or 30lb.
A round, low-diameter profile.
Super-fast sinking in weed green.
A fair price, with a 1000m option.
Descend is RidgeMonkey's sinking braid, with a round, low-diameter profile and a weed green colour. It's super-fast sinking and has virtually zero stretch, so you get direct contact and clear bite indication.
It comes in 20lb at 0.28mm and 30lb at 0.35mm, on 300m or 1000m spools, and it's highly abrasion resistant.
As with any braid, you'll want a leader, and some waters ban braid, so check the rules. For a fine, fast-sinking braid at a fair price, though, I think it's great value.
Pros
- ✓Round, low-diameter profile makes it sink super-fast
- ✓Virtually zero stretch for direct contact with the rig
- ✓Highly abrasion resistant, so it stands up to tough conditions
- ✓Slim diameters, with 20lb at just 0.28mm
- ✓Both strains come on 300m or 1000m spools
Cons
- ✕Only 20lb and 30lb, so no heavy option for snags
- ✕Needs a leader, and some waters don't allow braid
Frequently Asked Questions
What is the best carp fishing line?
The Shimano Technium is the highest-scoring line in this guide at 8.8, because its three-layer build gives low stretch, high abrasion resistance and a supple feel in one mono. If you want the line hidden, Korda Kontour is the fluorocarbon to look at, and for heavy weed, the Thinking Anglers SBX is the sinking braid.
Should I use mono, fluorocarbon or braid for carp?
Mono is the most versatile choice, because its stretch cushions lunges under the rod tip and it's the cheapest to fill a set of reels with. Fluorocarbon is harder to see and sinks fast but costs more per metre, while sinking braid has no stretch for direct contact in weed and at range but needs a leader, and some waters ban it, so always check the rules.
What breaking strain mainline do I need for carp?
Most carp anglers use 12lb to 15lb mono for open water, and step up towards 15lb to 20lb for snags, weed and gravel. Lighter lines cast further and sink more easily, so match the strain to your rod, your leads and the water you fish.
How often should I change my carp mainline?
Check the last few metres after every session and cut off anything that feels rough or nicked. Respool when the line has been damaged or has sat on the reel for a long time, because use and sunlight weaken mono over time, and a fresh spool is far cheaper than a lost fish.
Do I need a leader with my mainline?
A leader protects the end of your mainline over gravel and snags and helps pin it down near the rig, and a shock leader takes the strain of a hard cast at distance. If you fish braid, a leader is a must, and our leadcore and leaders range covers the options.
What line should I use on a spod or marker rod?
Spod and marker rods are usually loaded with thin braid rather than mainline, because braid casts further and gives you a clear feel of the lake bed. Our best spod braid guide covers the braids made for that job.
How much line do I need for three carp reels?
A 1000m spool of mono usually fills three big-pit reels, which is why bulk spools like the Trakker Mono Reel Line are such good value. Fluorocarbon and braid come on shorter spools, so many anglers put mono backing on first and top up with fluoro or braid.
Final Thoughts
If you want one dependable mono for most carp fishing, the Shimano Technium is the one to buy, and the Fox Exocet Pro is the pick for distance with a low-vis line.
For a mono that sinks fast and lies flat, the Gardner GT-HD is superb, while the Korda Subline is the tough one for snags and weed. The Trakker Mono Reel Line and Daiwa Sensor give you plenty for the money, and the Korda Basix is the budget choice.
If you want the line hidden, Korda Kontour and Thinking Anglers FTX are the fluorocarbons to look at, and for weed or long range, the Thinking Anglers SBX, Trakker Sinking Braid and RidgeMonkey Descend are the sinking braids.
You can compare more lines and live prices across our carp line range, and for spod and marker rods, our best spod braid guide covers the braids made for that job.
