Who it suits
Is it right for you?
Great for
- Pike fly anglers fishing deeper water. The Sink 7 profile helps large streamers work down where the fish are, rather than hanging in the upper layers.
- Anglers using heavier pike fly rods. WF 9/10 gives the line plenty of presence for loading a suitable rod and turning over chunky flies.
Maybe skip if
- Shallow, weedy or surface-focused pike fishing. A fast-sinking line can bury the fly in the snags or simply fish too deep for the swim.
- Anglers wanting one fly line for everything. This is a specialist full-sinker, so it’s much less flexible than a floating or intermediate line.

Quick verdict
A proper pike line for getting down deep
If you’re chucking big streamers for pike and need them fishing well below the surface, this line makes a lot of sense. The Sink 7 rating is the headline here: it’s built to get the fly down, not skate around in the top few inches.
The WF 9/10 rating and loading-friendly design suit the heavier rods and larger flies normally used for pike. It’s a specialist tool, though, so it won’t be the bob-on choice for delicate presentations, shallow weed or general trout work.

The design is purpose-built for demanding pike fly work, with a full-sinking profile, heavier rating and useful depth markers.
Sink 7 and the WF 9/10 format are well suited to getting large streamers down and loading a suitable rod.
Better depth control can put the fly in front of pike that a floating line simply won’t reach.
The markers help, but fast-sinking lines need careful countdowns and aren’t as forgiving in shallow or snaggy swims.
It offers a specialist job-specific performance, though the narrower use case means it’s best value for committed pike fly anglers.

The full rundown
Everything you'll want to know about the Airflo Sixth Sense Pike Fly Line
Pike don’t always want to smash a fly off the top. Sometimes they’re sat down deep, tucked beside a drop-off or sulking in colder water, and that’s where a proper sinking line earns its keep. The Airflo Pike Elbi’s Sixth Sense is built for exactly that sort of chucking.
This isn’t a general-purpose fly line with a cheeky sinking section added on. It’s a full-sinking pike line, classified as Sink 7, and designed around the sort of large streamers you use when you’re hunting a lump with teeth. The aim is simple: get the fly down and keep it working there.
The available version is WF 9/10, putting it firmly in the heavier pike-fly bracket. That’s the territory of powerful rods, chunky flies and casts where you need the line to load properly. If your usual fishing involves small dries or dainty little nymphs, you’re very much in the wrong aisle, mate.
For pike, though, that heavier rating is bob on. Big streamers have plenty of air resistance, and a line needs enough mass to turn them over without making every cast feel like a wrestling match. Airflo describes this line as loading the rod well, which is exactly what you want when there’s a sizeable fly on the end.
The Sink 7 rating is the real headline. It gives you a way to fish deeper without relying on a long sinking leader or trying to force a floating line down with loads of extra tackle. Cast it out, let it sink, then work the fly back with strips, pauses and changes of pace until you find where the pike are sitting.
That doesn’t mean you simply lob it out and wait for the line to do all the graft. Sink rate, retrieve speed, fly weight and water depth all play a part. In a deep lake, you might give it more time to reach the zone. In a canal, a shorter count could keep the streamer above the bottom and away from every snag in the swim.
The depth-identification markers are a dead handy touch. When a line is disappearing into dark water, it can be tricky to know how much has sunk and how repeatable your cast really is. The colour markers give you a visual reference, helping you count down consistently and get the fly back through the same depth on the next chuck.
There is a trade-off, naturally. A full-sinking Sink 7 line isn’t the most versatile choice for shallow margins, surface takes or weed-choked bays. If pike are cruising high, you’ll want a different line. But if your game is big streamers and deeper water, this is a focused bit of kit that should make the whole approach more controlled.
The main thing is matching it to the rest of your setup. Use a suitable 9 or 10-weight pike rod, a reel that balances it properly and a bite tippet that can cope with pike teeth. Keep your retrieve varied, watch the line for a take and don’t be afraid to fish the margins after searching deeper water. That’s often where a cheeky pike appears from nowhere.

Our take
The angle
The Sixth Sense is all about depth control with big pike flies. A full-sinking profile helps keep the fly working through the water column, while the colour markers give you a useful visual clue when stripping line and managing depth.
That makes it especially handy when pike are sulking deeper, when a cold-water session has pushed fish down, or when you’re fishing a reservoir, canal or deeper lake feature. You’ll still need to read the swim and vary the retrieve, but the line gives you a much better starting point than a floating line with a long, awkward sink-tip arrangement.
What you’re buying
A dedicated deep-fishing pike line
The Sixth Sense Pike is a full-sinking fly line with a Sink 7 classification. It’s made for pike anglers casting large streamers and needing those flies to spend proper time beneath the surface. The WF 9/10 rating gives it the heft expected for heavier pike tackle, while the loading-friendly design should help turn over bulky flies.
The depth-identification colour markers are useful on deeper venues. You can use them as a visual reference when counting the line down, making it easier to repeat a productive cast and retrieve. That’s a small detail, but it can save plenty of guesswork when the water’s dark and the fly is nowhere near visible.
Worth knowing. Sink 7 is a serious sinking profile. Let it down too long in shallow water and you’ll soon be dragging through weed or kissing the bottom. Count it down carefully, especially around snags and drop-offs.
On the bank
For deeper pike and bigger flies
This line suits the angler who has already got a pike fly setup and wants a dependable way to search deeper water. It should be particularly useful on reservoirs, deeper lakes and canals where fish aren’t always willing to rise for a floating presentation. Work the fly with strips and pauses, then adjust the countdown until you find the bite-time zone.
The WF 9/10 format is best matched with a suitable heavyweight pike rod. Large streamers need authority behind them, and the extra line mass can help the rod load without forcing you to false-cast a massive fly all day. Keep your casting tidy, give the fly room behind you and watch the line rather than waiting for a rod-bending smash.
Worth knowing. Take a floating or intermediate line as well if your venue has shallow bays, weedbeds or fish that are cruising high. The Sixth Sense is a cracking specialist option, but it shouldn’t be your only line for every pike scenario.
Quick answers
The bits anglers usually ask about
Can it cast big streamers? That’s exactly what it’s intended for. The WF 9/10 rating and pike-focused design give you the sort of line weight needed for larger flies, though your rod, casting stroke and fly profile still matter. A giant, wind-resistant fly will always need a bit more room and patience.
Is it suitable for shallow water? It can be used there with a very short countdown, but Sink 7 is more at home when you need to reach depth. Over shallow weed or a snaggy bottom, a floating, intermediate or slower-sinking option will usually be less of a faff.
How do the colour markers help? They provide depth-identification points along the line. Once you work out how long the line takes to reach a useful depth, those markers help you repeat the same presentation instead of guessing on every cast.
Worth knowing. Always pair the line with proper pike bite protection. A good sinking line won’t help much if the final connection isn’t built for sharp teeth.
