Default Hardy Zenith Sintrix - fly rod of the future?

This is a thread for discussing product focus article: Hardy Zenith Sintrix - fly rod of the future?

Be interested to hear who has cast a Zenith and what you thought of them? Worth checking out the Sportfish Zenith page linked to in the article for the product videos and extra information.

Surely more a 'small step' - in graphite rod build - than any 'quantum leap'?
Expect many blank builders to follow suit with similar reinforced resins. In fact some, eg St Croix, incorporated this technology into their top end 'Legend Elite' range sometime last year. St. Croix Moves to Nano-Particle Resin, Rolls Out New Rod Models | MidCurrent

From the Hardy link in the first post:

Hardy & Greys Ltd - SINTRIX

SINTRIX™ is the trade-marked brand name for Hardy & Greys new composite rod material. The material was initially developed by 3M in the USA for the aerospace industry.

3M has only awarded four fishing tackle companies licences to use its base silica nano matrix material.
Hardy & Greys Ltd. Is the only UK brand with a licence.

SINTRIX™ is carbon fibre held together with a resin impregnated with silica nano spheres. This technology is brand new and produces a material that is significantly stronger and potentially lighter than traditional carbon fibre.

I expect it will improve line speed, accuracy, distance and hook setting

I think nanotechnology is going to bring big improvements in composite materials - this is just the first application. This is putting silicon nanoparticles in the resin - I'm waiting with interest to see what can be done to the cloth with carbon nanotubes.

Hello All

I tend not to get to involved with discussions like this one, but in this case I thought I'd add my own view and some info for people to consider.

I, like many others don't believe that the new 3M resin is the giant advance that we see being touted in the press. The moves from cane to glass and then from glass to carbon were big leaps forward......this I don't believe is quite in that league, though perhaps similar to the jump from S Glass to the very early forms of carbon fibre. It is however a definite improvement on current materials.

It will most notably add strength and robustness to rod blanks. Anyone who's heard that sickening crack whilst playing a fish will agree that anything that reduces the chances of that happening has to be a good thing. Along with the added strength a reduction of weight will of course follow...again a good thing.

A few points to consider that I've recently seen mentioned.

"3M Matrix resin system delivers the following improvements:

76% improvement in shear modulus;
73% improvement in toughness;
68% improvement in Barcol hardness.

In composite structures like a rod - it delivers at least the following results:

25% improvement in compression strength;

49% improvement in in-plane shear stiffness:

The fundamental weakness of carbon fibre is a limitation in compression strength, even with circumferential support. The new 3M matrix system is a higher modulus resin, it supports the fibre to reduce or delay micro-buckling, resulting in a stronger, longer lasting product. By creating rods that are more durable and potentially lighter weight, you are increasing product performance while decreasing the chance for material failures. This means fewer returns and warranty claims and more satisfied customers."

The 3M system is certainly a leap in resin technology and it is primarily a safe and the best option for matrix reinforcement. The resin is reinforced with silica oxide nano particles. There are other offerings on the market that incorporate carbon nano tubes (SWNT). As I understand it, these are some of the most toxic, carcinogenic substances known to man and should be treated accordingly even when embedded in a resin matrix. Something to consider if for whatever reason you are machining a piece of that material and generating dust particles.

Whether all this is an amazing advance is debatable. A collection of small improvements tends to add up to 1 large improvement. Will it enable an average caster to suddenly be able to delicately drop a dry fly on a trouts nose at 30 yards? NO! However as I previously mentioned it will reduce (not eliminate) breakages and is noticeably lighter in the hand.

Lastly, the claim that Hardy's are the only UK firm to get the 3M license isn't entirely correct......watch this space......

Hey Steve, they're nearly 700 quid, of course they're better!!

While you're at it stick a vibration dampening microchip in will you, they have them in skis and I'm feeling most deprived.

Default Pro-axis

Fished with a Canadian pro-caster in Cuba over xmas. He had the Hardy Pro-axis to trial in different weights and the Loomis NRX.
Naturally I aked to have a wee go. Needn't have bothered, I just could not get to grips with the Pro-axis at all, no doubt down to my limited casting ability! The rod felt extremely stiff and the line collapsed behind me. The NRX was comparitively easy to cast. Both rods were 9wts.
The Canadian asked to try my Zane 9wt and stated that he found it a nicer rod to cast with (as he propelled the fly line and a heap of backing towards the mangroves)
A few days later he described the Hardy sintrix rods as 'very special' to fish with, quite unlike any rods he had experienced before. He certainly seemed to rate them after tangling with Bonefish, Jacks and Tarpon.
Perhaps this advanced material requires advanced casting technique to realise the rods potential? Think I'll stick to my Zane.

Hi Malcolm

Not sure if dampening chips will ever get into rods but I've heard talk of piezo electric fibres in rod blanks that alter the properties of a rod with the flick of a switch! Now that would be a big leap in carbon technology.

I had a demo rod out over the weekend, i was not fishing only casting with wool on the end of a tapered leader attached to a Rio i-line floater.

I am no casting expert but i thought it performs extremely well.m

Its not a stiff rod which i like although it recovers very fast..you could really feel the rod unloading get down to your local Hardy dealers and chuck a line with one, i dont think you will be disappointed
