Barrio ISS Spey Fly Lines

The Barrio ISS (Integrated Scandi Spey) range of lines are easy casting, short headed Spey lines in floating and intermediate densities for two handed rods. These have gained an excellent reputation, offering the angler a line that is accurate in short casts, easy distance casts when required and superb presentation of everything from small dressed flies to copper tubes - a hugely versatile line in keeping with the Barrio design ethos.

The ISS range is an ideal all-round line, but also an excellent choice where space is tight, when deep wading, when fishing large flies, or for hand-lining tactics. Much of the design and development work has been done with ease of use in mind and due to its all-round characteristics, it is also an excellent choice for those new to Salmon fishing.

Following final testing in the back-end of 2017, the Intermediate Head ISS is new to the market for 2018. It combines all the excellent properties of the floating ISS Spey in a new line which is designed to sink at about 1.5 inches per second. This makes it ideal for when you want to get down that little bit further in bigger water conditions, or in the spring and autumn.

Both the floating and intermediate ISS Spey lines have been designed to be fished with 10' polyleaders of all densities, or they can be matched to simple 15' tapered Salmon leaders.

Our floating ISS Spey lines (F) have a pale olive floating head and cream floating running line.

Our intermediate headed ISS Spey lines (IH) have a darker olive intermediate head and pale yellow floating running line.

Barrio lines do not have factory welded loops, we use salmon sized RM braided loops. These are available to order and are very easy to fit.

Price: £39.00 including free worldwide shipping.

This afternoon I tried my new 7/8 ISS Spey line in conjunction with a 7/8 12.5 feet Guideline Lpxe. It was a great pleasure casting this line on this rod. On the line attached a 10 feet poly leader with a 10 feet tippet. All casts were very powerful and achieved unexpected distances.

Either hand up, snake roll, single - double spey no problem at all. Perfect V loops , unrolling performance and accuracy.

A recommendable line for novice - and experienced casters who want to feel the line acting on the rod.

Been using my new ISS Spey line for a few weeks now and absolutely adore it.

Using it with my 12’9 Shakespeare Oracle Scandi rod. Casts like a dream.

Had the 7/8 line for several months now in use on my 7 weight Hardy Zenith 12ft 6. To date I couldn't be more pleased. This line will cast any poly tip or tapered leader and any weight of fly to boot. It makes a total mockery of the "black art" of successful Spey Casting. Wind, bankside obstruction, either hand up, all makes no odds. Total accuracy, razor sharp loops and delicate presentation are on offer for the merest input.

This line really is a game changer.

Having used Barrio switch lines for a number of hears I decided to try a 10/11 ISS Spey Line on my 14'6 Hardy Zenith Sintrix. Hugely impressed! Casts beautifully and I was amazed at how delicately I could present the fly on a 12ft leader.

Really smooth coating allows you to shoot line very easily. All in all just about the perfect line for the beat of the Usk that I fish! Also very reasonably priced.

Excellent line. So pleased I decided to get one of these in 10/11 weight. It matches a Guideline Le Cie 14' 8" rod perfectly and I can throw an accurate long line nearly every time. I think of myself as a novice caster though I've been salmon fishing for a while, but this line has changed that.

I recommend these lines wholeheartedly.

I have been out pretty much solely with the ISS during the past season with a 9/10 on my Mackenzie DTX:Atlas 13'7" #9wt and a 10/11 on my MacKenzie 'original' DTX 15'. I thought it might be useful to share some of my findings as an end of season review.

Incidentally these lines have also been tried on a wide range of rods including Gaelforce, Sharpes, B&W, Hardy, Shakespeare and CND - plus others I've probably forgotten.

In the tougher wind conditions experienced in the early part of the season up here in Inverness-shire the ISS was a perfect choice, it inspires confidence in anyone who uses it and in all conditions "I really can make that cast" and so on. I have experimented with 15' sinking polyleaders on both the 9/10 and 10/11 and whilst that's asking a bit of the 9/10 it coped very well. The 10/11 ... with impunity, it's as if they weren't there at all. Now this is interesting to me as although I use all sorts of polyleaders and 'T' tips, I do like using longer polyleaders, I'd simply not tried them on the ISS before.

As a self confessed tackle tart I've got all sorts of Salmon lines, some really really good and some harder to use but rewarding when you get it right. This season past I did more Salmon fishing than in any season in the previous 5, with an armoury of gear to choose from it's a testament to how good this line really is that I pretty much only used the ISS (exceptions were when my friend Euan borrowed it) as my go to line.

Salmon fishing next year? You should buy one, I don't think you can afford to be without one.

Bought the ISS Spey line after speaking to Mike and the line just loads so easily and shoots from the rod effortlessly.

A great line at a great price and I can now cover the whole river with ease.

Once again, fantastic service from Mike with next day delivery of my ISS Spey line.

I'll be out on the Don today to try it out on my Snowbee rod.

What a relief to finally have a great quality line. I have always been a Hardy line man, well, till I got my ISS Barrio, what a down right perfect casting line.
