Best Carp Fishing Line (2018 Review)

Carp Fishing Line Setup

Why is Choosing The Best Fishing Line Important?

As far as selecting the best carp fishing line, seasoned carp anglers may argue that its a personal choice as far as brand selection goes, there are a few issues you should consider before buying.

Line Strength – How strong should your mainline actually be?
Abrasion Resistance – Can it withstand repetitive casting. What about the wear and tear of time spent in the water?
Visibility – There are many colours and types of line. Pick one that will blend into the lakebed surroundings.
Quality – Believe us when we say a quality fishing line will last you a long time…

You’ll learn all about these terms in our carp fishing line reviews below.

So let’s begin our best carp fishing line countdown!

List of Carp Fishing Line

Daiwa Hypersensor Review

This may of been around for years now, but Daiwa Hyper Sensor is a really popular mainline!

It’s actually the ‘big brother’ of Daiwa Sensor (also a top quality fishing line) but offers a reduced diameter, which means less visibility, and a higher abrasion resistance.

That makes it well suited to carp fishing – especially through rougher weather conditions.

Many outlets offer a bulk deal, which means money saved for us anglers, with plenty of line to spool up all three carp reels if you like to keep your reels all the same.

Available line strength ranges from 5 lb up to 30 lb, covering a huge range!

We’ve picked out the recommended lines from these (both bulk and 300m spools) shown as follows:

Bulk Spools (Available to buy here)

Strength: 10lb – Diameter: 0.26mm – Spool Size: 1963m
Strength: 12lb – Diameter: 0.28mm -Spool Size:  1675m
Strength: 15lb – Diameter: 0.317mm -Spool Size: 1261m
Strength: 20lb – Diameter: 0.37mm – Spool Size:  1192m
Strength: 25lb – Diameter: 0.405mm – Spool Size: 772m
Strength: 30lb – Diameter: 0.435mm – Spool Size: 685m

300m Packs (Available to buy from here)

Strength: 10lb – Diameter: 0.26mm
Strength: 12lb – Diameter: 0.28mm
Strength: 15lb – Diameter: 0.317mm
Strength: 20lb – Diameter: 0.33mm

It’s made in Japan, and really is a decent budget carp line with a choice of two distinct colours to choose from – Original Dark or Gunmetal Grey.

How to Spool Up Your Carp Reels

An important aspect is learning how to spool up your reels correctly – this will save you valuable time if you were to experience a tangle fest down on the bank!

We’ve discovered a foolproof method of re-loading your reels that involves a bucket of hot water and using the correct angles when reeling in!

You’ll be glad you did!

Nash Bullet Mono Review

Brought back in from the 1990’s – the legendary ‘Bullet Mono’ is back with a bang!

Its very fast sinking, with a low stretch – and suited to long distance casting, making it a top all-round mainline for many angling styles.

Nash promise that “Bullet Mono has never been bettered for abrasion resistance – or strength”, and holds up well to all kinds of fishing knots.

Each spool contains 1000 metres (plenty for 3 carp reels), and is available in a hi-visibility green or brown – which matches both silt, gravel and weedy lakes comfortably.

It’s also very user-friendly fishing line and rattles of the reel sweetly on the cast with no signs of fraying, even after long periods.

Although we mentioned how strong this carp fishing line is, it’s surprisingly supple too!

These are the breaking strains on offer:

10lb – 0.28mm
12lb – 0.33mm
15lb – 0.37mm
20lb – 0.40mm

A neat little ‘bonus feature’ about Nash Bullet is that at every 250m mark, it is marked up for you to gauge how much line is used, or remaining. Sweet!

A great fishing line this – especially if you fish lakes that require a lot of extreme casting.

Carp Fishing Line: Are YOU Confident?

If you’re already familiar with carp fishing line this section may help!

A line break here, or a snap off there can really affect your confidence when dealing with carp fishing line.

There are many mainlines on the market (we’ve reviewed two already!) and there are poor ones too!

Diameters, breaking strain, abrasion strengths, suppleness and visibility are key features of choosing a line you can confidence in!

We’ve highlighted a really in-depth article (Courtesy of French Carp & Cats) that really explains all the technical aspect of line choice.

Choosing a Carp Fishing Line

A common question anglers ask  is “What breaking strain should I choose?”.

The plain answer is the heaviest you can get away with really….

If you’re casting short distances, 20lb is seen as a great option. Yes, it may seem a little heavy – but it won’t break very easily at all and you’ll feel confident the more you use it, especially with a heavy setup.

For longer chucks, you should maybe drop down to about a 15lb, or even 12lb mainline.

Couple this with a quality shock leader which will take the impact of a 4.5oz lead – which could snap your line clean if you don’t!

Why should you use a shockleader.

Some venues may insist on a minimum breaking strain of 12lb – so definitely worth checking this before you set off to fish!

Line Colour - Does This Matter?

Korda SUBline Review

Korda released ‘SUBline’ to accommodate all extreme angling situations.

Its silky smooth, sinks well and is available in green or brown to match the surroundings.

Korda SUBline Review

In testing, it passed key parameters like knot strength and toughness with flying colours, making it really stand out amongst tough terrain like gravel and weedy areas.

Korda SUBline

At the time, a lot of new line technology was used to maintain a good suppleness without the usual wiry feel some other mainlines offer.

SUBline is packed with a dense formula to make sure the line sinks as quickly as possible, making heavy duty carping a ton easier.

Available on a 1000m spool, this chart below highlights the available breaking strains and diameter ratings.

10lb – 0.30mm
12lb – 0.35mm
15lb – 0.40mm
20lb – 0.43mm

Also available is Korda SUBline Tapered Mainline.

Korda Subline Tapered Mainline

It has all of the original SUblines properties, but tapers into a shock leader at each end.

There are no knots required, because if you snap off – all you have to do is wind in to reveal another!

This miminises the risks of frapping, with nothing for weed to get trapped in.

(Each end has a 15m tapered leader btw)

A great fishing line alternative?

Sinking Your Fishing Line

Once you’ve mastered casting, another problem anglers may be faced with is how exactly to sink your mainline EVERYTIME.

Once you’ve mastered casting, another problem anglers may be faced with is how exactly to sink your mainline EVERYTIME.

All the work you’ve put into finding a feeding hotspot, underwater feature or patrol route can be messed up completely.

If your line zig zags up and down, or gets caught around weed or debris, this could spook carp in the vicinity.

Especially pressurised waters where carp are very switched on to mainlines in the water.

One method you could use is to try attaching backleads.

The video below explains how to do this in a little bit more detail.

Using Backleads

Alternatively, a trick I like to do is place my rod onto my rod rest for about a minute or two before I wind in to tighten everything up.

That way, your line will naturally sink, and then you can tighten up very slowly until you feel pressure between the rod tip and the lead.

Obstacles are hard to avoid – but if you use a marker lead, you can gauge any weed or debris between the bank and your chosen spot.

For those unfamiliar on using marker leads, again, the video below will really help you learn how to improve this side of your angling.

Shimano Aero Specimen Review

Shimano Aero is a good value for money mono, yet is surprisingly strong and long lasting.

A carp fishing line should last you years, and the Aero stacks up to this!

In a nice matt brown translucent colour, its very versatile, with breaking strains ranging from 8lb to 18lb on offer.

With an exceptionally high knot strength and good abrasion resistance, the low memory of this fishing line ensures a decent casting performance, no matter what angling situation your faced with.

ESP Syncro XT Loaded Review

Also available is ESP Syncro XT Loaded – which is quite possibly one of the best carp fishing line on the market!

Retaining all the characteristics of the original, it has a dark olive pigment, unbeatable knot stength and disappears against any lake bed backdrop.

Fox Exocet Carp Fishing Mono Line

This trans khaki monofilament is of low visibility which really helps to blend into the lakebed once your line has sunk.

Above all, it virtually ‘disappears’ when resting on the bottom and in mid-water if you’re fishing tight lines.

Likewise, Fox Exocet is very supple and has a low diameter (0.309mm), with five available breaking strains of 13lb, 16lb, 18lb, 20lb and 23lb.

Considering this low diameter, we were surprised at the low abrasion resistance, great knot strength and low memory.

As we know, this makes long casting a breeze!

Wrapped up onto 1000m spools, there is plenty to go around – so spooling up three carp reels will be no problem at all.

In conclusion, Fox Exocet is a very versatile carp fishing line that anglers will enjoy using whatever the angling situation.


5 breaking strains of 13lb, 16lb, 18lb, 20lb and 23lb.
Low visibility
Low diameter (0.309mm)  and supple
Great abrasion resistance
Sinks surprisingly well for such a supple line
Great knot strength and low memory

Carp Fishing Knots

We wanted to round-up our best carp fishing line post by showing you some helpful videos on tieing knots!

You see, when tieing fishing knots, it can affect the breaking strain – like when attaching your leaders for example.
