Barrio Mallard Fly Lines

Barrio Mallard fly lines, the original 'Barrio Lines' that we designed, tweaked and refined back in 2004.

Our Mallard fly lines have gained a strong following over the years and these conventional weight forward and double taper profiles 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. Suitable for most 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 floating fly lines are available in our natural cream colour in weight forward WF3F to WF8F and double taper DT2F to DT8F.

Price: £25.20 including free worldwide shipping.

I recently ordered the Mallard DT4 and took it to the Eastern Sierras for some winter time Baetis fishing. It's a fantastic fly line. It loads cleanly, carries long casts with ease and lays down flawlessly.

I will also say that when roll casting it performed beautifully. Most of all at 34 U.S dollars I can hardly believe the value considering the fact that the major american Fly Line brands are charging at least twice that amount!

I have the feeling I will be ordering many more of these lines in the future!

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 any one to try and as a new season is soon opening, these are still my lines for 2013.

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.

Looking for a reasonably priced DT line I stumbled upon the Barrio Mallard DT. Being used on a Sage VXP #5 blank the DT5 is at the lower end of the "what feels right" scale, still offering excellent performance and casting with ease.

I will definitely try other Barrio lines from now on - thanks for the great work!

I found a spare spool in need of a line. For a moment, I found myself contemplating purchasing another brand of line to fill its emptiness. I even started to browse the extensive selection available on another of my favourite online retailers. Fortunately, then I came to my senses and ordered a Mallard DT3F.

I've lost count of the number of Mallards I now own, WF and DT. The DT3 just ordered is specifically for a small, overgrown Dorset chalkstream where space is limited. 7ft 3wt rods are the order of the day, with roll casting de rigeur. The Mallard DT3 roll casts superbly.

Value for money is superb - highly recommended, even by the wild brown trout of Dorset!

I use the Barrio Mallard exclusively for my fishing and casting practice. The suppleness, taper and overall profile is perfect for the high speed casting necessary for the Italian Style of casting.

The Mallard DT 3 line outcasts most other brands. Highly recommended for general fly fishing or for the Italian style.

Best freakin line I've ever used! Received the carefully packaged DT3F line today along with a little hand written thank you for purchasing note. Two thumbs up for that.

I strung up the line on a featherweight / Hardy midge fiberglass combo and started fishing in the canal which runs through my backyard. From the moment I made the first cast, the line put a smile on my face which lasted until I stopped fishing because the sun had set. I couldn't stop fishing, it's simply that good.

The presentation, the subtlety, the tight loops, trademarks I never encountered in other lines before. I knew the rod had more soul than she showed me before with other brand lines, but this blew my mind, never would have imagined that a line could make such a difference. Sure enough my next lines will all be Barrio lines!

Thanks again and keep up the good work, it looks like you've got a new lifetime customer...

Mallard DT6 -: bought this line in Feb 2015 and have found it performs exactly as it should, it has excellent turnover, no memory and casts like a dream.

I only fish medium sized still waters, using nymphs or dries, so presentation is also very important and I am very very happy with it's overall performance so far, having fished in all conditions from strong winds to flat calms, all from the bank. I would highly recommend this line to anyone who prefers this style of fishing.

I have paired the Barrio Mallard 3 weight Double Taper with a 10ft rod. You always expect a 10ft rod to feel top heavy and it did with all the previous fly lines I used. This fly line transformed the rod completely and I use it now confidently for both nymph fishing and dry fly fishing. The presentation is absolutely perfect!

Ho comprato da Mike Barrio la linea Mallard DT4 , provata nel torrente , devo dire che e una linea furtiva per trote sospettose, si comporta bene con belle pose, ottima anche nel lungo linea,ottima da consigliare.

Had the DT5 for two seasons. A sublimely lovely line, virtually no memory, casts with ease.

I just have one reservation about the colour and wish perhaps the front 20ft or so was a sage or olive colour, then it would be just about perfect.
