Drennan Supplex Fluorocarbon
50m spools · 0.9lb to 10lb
Proper fluorocarbon, a useful spread of diameters and 50m to work with. A handy option for thoughtful coarse anglers, rather than a magic fix for a quiet swim.
- Made from 100% fluorocarbon.
- Supplied on 50m spools.
- Listed strengths run from 0.9lb to 10lb.
- Listed diameters run from 0.075mm to 0.30mm.
Make sure it’s the right one. This is Drennan Supplex Fluorocarbon, made from 100% fluorocarbon, not standard Supplex nylon. We haven't tested it on the bank.

Who it suits
Is it right for you?
Great for
- Silverfish anglers refining light rigs. The fine-diameter choices give you room to balance small hooks and baits with suitably light tackle.
- Coarse anglers tying their own hooklengths. A 50m spool and a broad strength range make it practical to prepare hooklengths for different float and feeder jobs.
Maybe skip if
- Carp anglers tackling heavy weed or snags. This isn't a substitute for a suitably robust, purpose-chosen carp hooklink and a safe approach to the swim.
- Anglers wanting one material for every presentation. Nylon, braid and fluorocarbon behave differently; the most discreet-looking option isn't always the best-moving one.

Proper fluorocarbon, a useful spread of diameters and 50m to work with. A handy option for thoughtful coarse anglers, rather than a magic fix for a quiet swim.

Quick verdict
A useful hooklength option, not a shortcut to bites
Supplex Fluorocarbon makes sense when you want a low-visibility hooklength and plenty of choice over diameter. The fine options are particularly interesting for careful silverfish work, while the heavier versions broaden its coarse-fishing uses.
Buy the strength your swim demands, not the thinnest one you reckon you can get away with. It's a sensible material to have in the box, but neither fluorocarbon nor a fancy label can rescue poor feeding or an unbalanced rig.

The 100% fluorocarbon construction and clearly defined diameter choices make a convincing offering, although durability hasn't been tested here.
The material and strength range offer useful presentation options, with actual knot behaviour and handling still untested.
A suitably chosen hooklength can support better presentation, but there's no basis for promising extra bites.
The spool format suits home-tied hooklengths, though fine fluorocarbon demands careful knotting and regular checks.
The 50m length offers useful scope for short hooklengths, but this is a tentative judgement without a confirmed price.

The full rundown
Everything you'll want to know about the Drennan Supplex Fluorocarbon
Drennan Supplex Fluorocarbon is one for the angler who actually thinks about the little length of line next to the hook. Not glamorous, granted. Nobody's gathering round your peg to admire a spool of hooklength material. But when you're balancing a small hook, a couple of maggots and a float dotted right down, that choice matters. This is 100% fluorocarbon on a 50m spool, with options running from proper fine silverfish territory through to heavier coarse work. There's a useful spread here, rather than one supposedly do-everything diameter.
First, a quick bit of honesty over the brew: we haven't used this product on the bank. This is a look at what it offers and where it makes sense, not a tale about bagging up after a miraculous hooklength change. The confirmed material, spool length and diameter choices give us plenty to work with. They don't tell us exactly how every knot will behave in your hands, or whether your local roach will suddenly stop being awkward. Anyone promising that from a spool label is having a laugh.
The fine end is what makes the range especially interesting for careful coarse fishing. There's a 0.9lb version at 0.075mm, followed by several steps upwards rather than a whopping jump straight into heavier line. That gives you room to build a balanced approach around small hooks and modest fish. Think light pole rigs or delicate float work, with elastic or a rod action that protects the hooklength. It isn't an invitation to chase bonus carp on thread. If bigger fish are likely, choose with those fish in mind before the float buries.
Fluorocarbon's attraction is its relatively low visibility underwater, but let's park the old invisible-line chat. Fish can still detect line, and presentation involves more than whether they can see it. Diameter affects how a bait behaves, while the material's stiffness can influence how freely it moves. A tiny bait falling through the water and a bait sitting on the deck aren't asking exactly the same thing of a hooklength. Supplex Fluorocarbon gives you another option to consider; it doesn't make your existing nylon suddenly a bit naff.
Moving up the range, you've got options such as 4.4lb at 0.17mm, 6.4lb at 0.22mm and 8lb at 0.25mm, with 10lb at 0.30mm at the top. Those broaden the possible uses across float and feeder fishing, provided the chosen strength suits the job. Don't read the biggest figure and automatically think heavy carp work, though. Fishing open water for modest fish is a different proposition from trying to stop a lump reaching roots in the margins. Cover, abrasion risks and how much pressure you need all belong in that decision.
The 50m spool is a handy format if you tie hooklengths ahead of a session. You can get a useful stock of short ones ready without treating every fresh length like the last biscuit in the tin. Label your storage with diameter, strength and hook size, especially if you're carrying several similar-looking materials. That's a tiny bit of shed-time faff that saves a lot of squinting on the bank. How many hooklengths you get depends on their length, knot waste and how often you scrap a dodgy one.
Care at the tying stage matters, particularly with the finest options. Use a knot suited to the material and your hook, lubricate it before tightening, draw it down steadily and check the finished hooklength with a controlled pull. A stated breaking strain isn't a promise that a rushed knot will hold that load. Run your fingers along the line after a fish or contact with something rough, too. If you find damage, replace it. Saving a few inches isn't clever if the next decent fish leaves you gutted.
So where does it fit? In the box of a coarse angler who likes having a reason for each rig choice. It's especially appealing if you want to explore fine fluorocarbon hooklengths without losing the option to step up within the same range. Keep the expectations sensible, match it to your tackle and concentrate on feeding, depth and bait presentation as well. A well-chosen hooklength can support that whole approach. It won't turn an empty spot into a fish-filled one, mate, but it gives you another useful tool when the details count.

Our take
Think diameter first
The useful bit here is the choice: from 0.075mm at 0.9lb through to 0.30mm at 10lb. That lets you match the hooklength to your hook, bait and likely fish rather than forcing one spool into every job.
Low visibility is only part of presentation. How freely the bait moves, how the hook sits and whether the hooklength survives the swim matter just as much.
What's on the spool
Closer look: proper fluorocarbon, plenty of choice
You're buying 50m of 100% fluorocarbon for making your own hooklengths. The range spans 12 listed strength-and-diameter pairings, so check the actual spool rather than ordering on the Supplex name alone. The 2.6lb version is 0.13mm, for example, while 5.6lb is 0.20mm. Those are different tools for different rigs, not just interchangeable labels.
Fluorocarbon is denser than water, so sinking behaviour is part of its appeal. That doesn't mean a short hooklength will pin an entire rig perfectly to every lakebed. Bottom shape, line tension and the rest of the tackle still have a say. Likewise, don't assume this is stiff boom material simply because it's fluorocarbon: diameter has a big influence on how a length behaves.
Worth knowing. The printed breaking strain isn't a guaranteed finished-rig strength. Knots, wear and damage all matter. Check each hooklength before fishing and bin anything suspect.
Picking the right job
Who it suits: anglers who like a balanced rig
Light-tackle silverfish anglers have the clearest reason to look at the fine end. If you're making up small-hook rigs for cautious bites, the diameter choices let you adjust one part of the setup without a massive leap. Keep everything balanced, though. A fine hooklength paired with unforgiving tackle is asking for a frustrating afternoon.
Float and feeder anglers can look further up the range according to the venue and target fish. Prepare a few sensible alternatives before heading out, then change with a purpose. If you're comparing materials, keep hook size, bait and hooklength length consistent where practical. Otherwise, it's hard to tell what actually helped.
It's less convincing as a blanket recommendation for dedicated carp fishing or snaggy swims. Choose a hooklink that suits the pressure and hazards involved, and avoid fishing situations where you can't safely control the fish. Nor should you ditch soft nylon for every falling-bait presentation. Sometimes freedom of movement matters more than the fluorocarbon selling point.
The bank-side questions
FAQs in full: material, strength and visibility
Is it coated nylon? No, Supplex Fluorocarbon is 100% fluorocarbon. That's the important distinction when shopping, because standard Supplex nylon is a different product. Make sure the spool actually says Fluorocarbon before you fill your hooklength box.
Which strength should you buy? Start with the swim and likely fish, then balance the hooklength with your hook, mainline and rod or elastic. The finest options have specialist uses; they aren't automatically better because they're harder to see. If cover or bigger fish demand more strength, step up rather than gambling on landing everything gently.
Is it invisible underwater? Afraid not, mate. Fluorocarbon's optical properties can make it less conspicuous, but there's no guaranteed disappearing act. A change might help a presentation, yet feeding accuracy, depth and bait behaviour can be far more important. Don't spend the whole session swapping hooklengths while ignoring where the fish are feeding.
On paper
Pros & cons

Your questions answered
What anglers want to know
The stuff you’d ask your mate on the next peg. Straight answers, no waffle.
01Is Supplex Fluorocarbon coated nylon?
Is Supplex Fluorocarbon coated nylon?
No. This product is 100% fluorocarbon. Don't confuse it with standard Supplex nylon.
02Which breaking strain should I choose?
Which breaking strain should I choose?
Match it to the fish, swim, hook and the rest of your tackle. Fine silverfish rigs and open-water fishing can call for a very different choice from bigger fish near cover. Don't drop strength purely to chase extra bites.
03Does fluorocarbon disappear underwater?
Does fluorocarbon disappear underwater?
No. Its optical properties can help reduce visibility underwater, but it isn't invisible. Diameter, light, viewing angle and the surroundings still matter, and fewer visible clues don't guarantee more bites.
