Barrio Mallard Fly Lines

Barrio Mallard Weight Forward fly lines, the original 'Barrio Lines' that we designed back in 2003.

Our Mallard fly lines have gained a strong following over the years and these classic lines are just as popular now as they were back then.

A simply superb fly line for traditional trout fishing tactics, anglers of all levels of casting ability will find the Mallard an enjoyable line to cast.

Equally at home with today's fishing styles and techniques, these well balanced fly lines are certainly capable of casting a good distance, but more importantly, they encourage the enjoyment and satisfaction of accurate and delicate presentation casts at normal fishing ranges.

Barrio Mallard weight forward floating fly lines are available in our natural cream and buckskin colours in WF3F to WF8F.

Country of manufacture: Made in the UK.

Price: £28.80 including free worldwide shipping.

The vast majority of my fly fishing is on rivers for Brown Trout with both dry fly & nymph. The Barrio Mallard in WF3, 4 & 5 has been my fly line of choice for a number of seasons now and has never let me down.

It floats well, has a nice front profile, lies straight, has a slick surface and a price that would no doubt be double if marketed from another stable.

An excellent line for both beginner & veteran.

Being a small stream angler, be they in the valleys, glens or mountains, I was always on the search for a fly line that rose to my needs. After going through a lot of lines & a hole in my wallet, I was never happy with the lines I fished, more in putting up with their stiffness & bumpy travel up through the rings on cold mountain streams & endless Memory, that is now long in the past.

I have been using mike's lines for 2 seasons now & would not replace them for any other make. They do what mike says they do, with no big fancy sales hype that we are all seeing now with lines 3 times the price & more.

They cast very well, I'm using the mallard every time I'm out, this would add up to a lot of days stream side. Pull from the reel & hang with almost no memory, shoot nicely & float highly, I make short casts that need to be right first time, the mallard gives me this, every time.

I can spend more time enjoying fishing & not worrying about stiff lines & the problems they intail, just lift the rod & shoot the line where it's needed. I have fished these lines long & hard, with plenty of life still in the lines and no cracks showing.

I would recommend these lines to anyone to try and as a new season is soon opening, these are still my go to lines.

Had a few of these lines over the years now, very pleased with them all. I am not an expert caster but these lines have made it a lot easier for me with both distance and presentation.

Good lines at a good price, thanks.

I bought my first Barrio line and tried it today, paired with my brand new Helios 3D 5wt. The line has no memory whatsoever, is very supple and lies straight as can be on the water. I have been using a Scientific Anglers GPX which is a half line size heavy and very front loaded, so it took me a little while to adjust to the way the Mallard line handles.

You can certainly get long casts with this line and it lands very gently on the water if you want to fish small dries. It’s not a distance line however and you need to get some line out of your rod tip so that the belly can give you good distance. This is not a bad thing, as distance lines can hit the water with a bit of a splash - something that you do not have to worry about with the mallard.

It’s a great all round line ..... it has power when needed, but can give gentle presentation when you want it too. I treated the line with the Barrio Line Care product and it floated really high, so no sink tip issues when fishing the dry ..... I'm very happy with the line and will get a GT125 for my 7wt next.

I've been using Mallard fly lines for a couple of years now. These lines consistently impress with their movement and delivery. The performance is excellent, offering smooth actioning of the rod, movement through the guides, distinct lack of memory and delivery of controlled power.

These lines deliver assurance that each cast will be what you want, where you want (be that at very short distances or reaching out to those rises). Whatever your casting style, Mallard lines put the control back into your hands and deliver the fly with seamless transition and delicate presentation.

Do yourself a favour and switch out to these lines.

Recently emailed Mike and asked for a floating line recommendation to suit my Sage 9.5 foot 7wt RPL+ for stillwater fishing. He gave me two suggestions and I decided on the Mallard WF 7wt.

After the first few casts, pretty poor, but that was just me getting the feel of the line with the rod. Wow, as I got my act together the line just flew ... super slick line, floats well, lands well, but with a few coils, me again, I should have given it a gentle stretch first.

Service from Mike Barrio second to none, no rip off postage costs, great response to emails and a real pleasure to deal with. I should add that this is my second line from Barrio and it will not be my last.

Great lines - tried many lines in previous years, I wont go anywhere else now, quality is outstanding.

I use the Mallard for mostly loch / stillwaters, shoots great, no coils and floats to the tip.
