What is the Eikre Fly Aquila Demersio fly line?

The Eikre Aquila Demersio is a clear intermediate fly line from the Norwegian fly fishing brand Eikre Fly. Clear intermediate fly lines, or slime lines, are translucent lines that sink slowly and allow you to reach trout feeding just below the surface. They're ideal for fishing nymphs and lures on stillwaters for rainbows and browns, and for sea trout.

Unlike some other clear intermediate fly lines, these ones aren't completely clear. Eikre says that they think the completely clear intermediate or glass fly lines reflect the light too much, so they've produced theirs with a subtle beige tint to help them blend into the surroundings a little more. They're also not a bog-standard intermediate when it comes to density and sink rate...

What's different about these fly lines?

Eikre says the Aquila Demersio intermediate is a "fast slow" intermediate "designed for presentation at all distances in both freshwater and saltwater". What this basically means is that the line is a slow intermediate but has a fast intermediate front section, giving a slightly different presentation to some other slime lines.

What sizes are available?

The Eikre Aquila Demersio comes in five different line weights from a #4 (unusual in an intermediate line) up to an #8. The #4 and #5 lines are both 90 feet long, but the #6, #7 and #8 are all 100 feet long.

The head lengths are average at around 37-39 feet, depending on the line weight. All of them have a "smooth presentation taper" that isn't too aggressive and has a semi-clear finish that Eikre says reduces reflections from sunlight and increases your catch rate by reducing visibility.

Do they have welded loops?

Yes. Unusually for this style of intermediate line, the Aquila Demersio is fitted with welded loops at both ends, so there's no need to faff about with nail knots. You can simply tie on your backing and attach your leader with a loop-to-loop connection to prolong the lifespan of the welded loop. This is a nice touch.

Weirdly, my line (purchased from an eBay seller) didn't come with any loops, despite the box stating they were present. I welded my own loops very easily using some heat shrink tubing and a set of Mrs Fly and Lure's hair straighteners.

What does it feel like in the hand?

Some clear intermediate fly lines can be stiff, coily, and have lots of memory. Thankfully, the Eikre Aquila Demersio isn't one of them. It has a soft, slick, slightly rubbery feel to it and reminds me a lot of the old Loop clear intermediate lines.

It hangs fairly limp, gets nice and slippery when wet to aid shooting, and has virtually no stretch, so bite detection is good but you can't give it a pull to help it straighten better. Like most clear intermediates, it can initially feel a bit sticky, but shoots through the rings nicely once wet.

What are these lines like to cast?

The Aquila Demersio casts very nicely on my Loop Cross SX and does not feel overweight like some other intermediate fly lines, so the presentation is delicate with minimal splashing. It's nice and stable to cast and shoots very well once wet. However, you can feel the slightly heavier tip and may need to slightly adjust your casting stroke to compensate. 

The front six feet or so of the line sinks noticeably faster than the rest of the line (exactly as claimed by Eikre) while the rest of the head and running line sinks slowly or hangs just below the surface. It's a good line for fishing just under the surface and never drops particularly deep unless you increase the countdown significantly. 

The taper is not very aggressive, so it's better suited to smaller nymphs and lures than big bulky patterns, but still works fine with regular lures and bead-headed flies. It's an enjoyable and delicate line to use on stillwaters.

How much do they cost?

The Eikre Aquila Demersio is now discontinued and has been replaced by the new Demersio Evo fly line. Those retail for around £65. This one was picked up from eBay for under £20.
