Who it suits
Is it right for you?
Great for
- Coarse anglers who fish several styles. The supple mono works across float, feeder and method setups, so you’re not tied to one sort of session.
- Commercial carp and mixed coarse anglers. The 5lb to 12lb options give you sensible choices for margin work, method fishing and general carp gear.
Maybe skip if
- Anglers fishing very large waters. A 100m spool may not give the line capacity or spare length you want on a big pit reel.
- Specialist snag and rough-ground carp anglers. A dedicated abrasion-focused carp mainline may offer more confidence when weed, roots or sharp edges are a constant threat.

Quick verdict
Verdict
Drennan Supplex Carp Line is a properly versatile mono for coarse anglers who want one supple, clear line that behaves nicely across float, feeder and method work.

The full rundown
Everything you'll want to know about the Drennan Supplex Carp Line
There’s a lot to be said for a mainline that just gets on with the job. No daft gimmicks, no faff, no trying to turn your float rod into a spaceship. Drennan Supplex Carp Line is a clear monofilament made for everyday coarse fishing, with the range stretching from delicate 3lb tackle right up to a chunky 12lb option.
That makes it a useful shout when your fishing jumps between styles. One day you might be trotting a float for silvers, the next you’re clipping up a feeder for bream, then you’re chucking a method feeder towards a commercial island. Supplex is aimed squarely at that sort of mixed bag, and the ultra-supple, limp feel is central to the appeal.
For float work, supple line is proper handy. It comes off the spool nicely and doesn’t feel overly wiry when you’re mending line or holding back the float. The clear finish is also a sensible choice when you want your mainline to be less obvious, especially in clearer water or when the fish are being a touch picky.
Move onto feeder fishing and the same softness helps with casting and general handling. It’s not being sold as a specialist distance or sinking line, so don’t expect magic tricks, but it’s a practical mono for normal swims and sensible ranges. Match the diameter to the feeder size and the fish in front of you, and you’re in the right ball park.
The method-feeder side is where the broader breaking-strain range starts to make real sense. A 5lb or 6lb setup can cover plenty of commercial carp situations, while the 8lb to 12lb versions give you more breathing room when a lump heads for the margins. That extra margin matters when reeds, islands and underwater rubbish are part of the swim.
The range runs through seven options: 3lb, 4lb, 5lb, 6lb, 8lb, 10lb and 12lb. In diameter terms, that’s 0.14mm through to 0.28mm. The lighter 0.14mm version is around 1.36kg strength, while the 0.28mm 12lb version is approximately 5.45kg. There are useful steps in between, rather than one huge jump from light to heavy.
The 100m spool length is worth thinking about before you press the button. It’s dead handy if you’re refreshing a reel or loading a sensible amount onto a coarse reel, but it may feel a bit tight on larger carp reels. Check the reel capacity, and don’t blindly fill a big spool with a single short length if you want plenty of reserve for long casts.
Drennan also puts toughness and abrasion resistance into the description, which is reassuring for everyday bank work. Still, no mono makes you invincible around mussels, roots, brickwork or savage weed. Use the right strain, inspect the first few feet after a fish or snag, and chop off any rough section before the next bite-time.
The main appeal, then, is balance. Supplex isn’t trying to be an ultra-specialist line for one exact venue. It’s a friendly, versatile mono that should suit anglers who want reliable handling across float, feeder and method fishing. Pick sensibly, spool it neatly and it looks like a proper bob-on choice for normal coarse sessions.

Our take
Why this mono makes sense on the bank
The big selling point here is versatility. Supplex is limp and supple, so it’s easy to fish with under a float, through a feeder rod’s guides or on a method setup without feeling like you’re wrestling a spring.
Pick the diameter to match the job rather than simply grabbing the heaviest option. The lighter sizes are bob on for general coarse fishing, while the 8lb to 12lb versions give you a more sensible margin around carp, snags and rougher margins.
A simple, versatile mono
What you’re actually buying
Drennan Supplex Carp Line is clear monofilament supplied on a single 100m spool. It’s ultra-supple and limp, with a range of breaking strains from 3lb to 12lb. That gives you plenty of room to tailor the line to a light float rig, a feeder setup or a commercial-carp method rod.
The diameters run from 0.14mm to 0.28mm. The 3lb, 4lb and 5lb versions are aimed more towards lighter general coarse work, while the 6lb upwards options start making more sense when carp, heavier feeders or snaggy margins enter the picture. It’s a practical range rather than a one-size-fits-all job.
Worth knowing. The 100m length is ideal for many coarse reels and fresh line changes, but check your spool capacity first. On a big pit-style reel, you may need backing or a longer spool to get the fill and line capacity you want.
Match the line to the swim
A good fit for mixed coarse anglers
This line suits anglers who jump between float, feeder and method fishing and don’t want a different mainline for every rod. Its limp feel should make everyday handling easy, while the clear finish is a sensible all-round choice when presentation matters.
For a commercial, the 5lb, 6lb, 8lb and 10lb options will cover plenty of situations, depending on the fish, snags and hooklength arrangement. The 12lb version is the beefier choice for margin work or heavier carp gear. Just remember that breaking strain alone isn’t a substitute for sensible drag settings and a decent landing net.
Worth knowing. Don’t automatically choose the heaviest line. On a delicate float setup, oversized mono can affect casting and presentation. Choose the lightest diameter that gives you a comfortable margin for the venue and target fish.
Quick answers before you spool up
The useful bits, without the waffle
Is it only for carp? No. Despite the name, the range is built for float, feeder and method-feeder fishing, so it can cover plenty of coarse situations. The lighter sizes are just as relevant to general match-style fishing as the heavier sizes are to commercial carp.
Can it handle abrasion? It’s designed to be tough and abrasion resistant, which is useful around normal coarse-fishing hazards. For truly brutal snags or sharp, rough features, give the line regular checks and consider whether a more specialist mainline would bring extra confidence.
Worth knowing. After a snag, a fish rubbing through weed or a hectic landing-net job, run the line between your fingers. If you feel a nick or rough patch, cut it back. It’s a tiny bit of faff that can save a proper gutter later.
On paper
Pros & cons
What we like
- Very supple and limp, making it pleasant to cast and fish with.
- Clear finish keeps the line visually unobtrusive in the water.
- Useful range of breaking strains for float, feeder and method work.
- Designed to offer toughness and abrasion resistance for everyday coarse fishing.
Worth knowing
- A 100m spool can be a bit limiting on larger reels or when you want lots of backing and spare line.
- The softer feel that helps presentation won’t suit every angler fishing seriously snaggy or abrasive venues.
- No specialist low-stretch or sinking-line feature is highlighted, so it’s a straightforward mono rather than a technical niche line.
