I guess Zyex isn't anywhere close to gut in terms of comfort.
Thank you for taking the time to answer the question. I appreciate your review.
I am finding Monogut ZX (brown) strung at 50 pounds (full bed) to be very comfortable and powerful. I've had a lot of shoulder/arm problems over recent years which is why I have trying out a variety of soft strings. ZX is my favorite in terms of both performance and comfort (Head sonic pro was good too but only for a few hours). I was previously using Dynamite 17 soft/natural. What I found with Dynamite (also made of zyex but a multi) was that it was very tension sensitive. There is only a narrow range of tensions where it plays well. I almost gave up on Dynamite the first time I had it strung. Unlike syn gut which has a wide range of acceptable tensions. Luckily ZX worked (right tension) first time for me.
I am still on my first set of ZX. I was going to raise the tension to 52 for my next re-string, but I am enjoying it so much, I think I will stay with 50 pounds.
You won't mistake it for gut regardless of what the numbers say. I can't imagine monogut is any softer than the multifilament version of their zyex line.
I think what you are trying to get at here is exactly what makes Monogut ZX a unique string. Both Nylon and Zyex stretch quite a bit. Zyex actually may stretch a little more. The difference comes in the materials ability to recover or bounce back from that stretch. Zyex does this part much better than Nylon. I think what you are describing as stiffness here is the excellent rebound effect of the Zyex recovering or bouncing back from the stretch. Since Nylon doesn't react this way it may feel less stiff when in fact it is simply not recovering from the stretch as well. This phenomenon has been measured as Dynamic stiffness which is the measurement listed as stiffness on TWU. This is exactly what gives ZX its power and arm friendliness. It also explains why you describe ZX as stiffer than Syn-Gut, yet report no arm problems. If it were actually stiffer, your arm would tell you.
Have you demoed the 300? I liked it on paper, especially the low flex combined with the Prince-like headshape, but on court it had a very muted feel and was very "blah."
You don't need to hear it from me since others, with no stake in the game, have already said it, but, ZX in a full bed should be fine for your arm.
Check out TWU string finder under the catagory arm friendliness. ZX is only best by naural gut strings.
Definitely. Even though it feels slightly firmer than a multi when striking the ball, I have absolutely zero arm/shoulder/back/body fatigue from hitting with this string, and that's playing 2-3 hours a day, several days in a row.
Exactly. The firmness of the stringbed comes from the ability to strech and return. As opposed to a poly stringbed, where the firmness comes from an inability to strech to begin with.
Don't confuse the firm stingbed with stiffness (inability to strech) because ZX stretches quite a bit. Zyex just handles the stretch better than any other synthetic material used in a tennis string.
I should also point out that while the string felt very stiff, it did not cause me any arm issues.
Great to hear. I look forward to trying out a full bed without worrying about my elbow.
I haven't demoed the 300. That's a good point that it looks great on paper, but might feel lackluster. What are your thoughts about it?
Awesome thanks for the affirmation
I just felt it to be very "blah." Nothing special, either in what I could do with the ball or how the stick felt. Couldn't recommend it. Although, of course, your taste in frames might be very different, so definitely demo it if you have a chance.
We find that since Monogut ZX is a slick monofilament string, any scuffing or scatching of the string surface comprimises the strength and severly increases the possibility of breaking during stringing or premature breakage during play. With that in mind, here is the word for word explanation of my stringing guru since this is not my area of expertise:
"By releasing the base first there is no possibility of residual tension scuffing the string as "the string clamp" is released. Imagine you have tensioned a string and clamped it. Then pulling the next string will attempt to pull out some of the "drawback" but can't because the string is clamped.
So, there is tension pulling on the clamped string and if the string clamp is released before the clamp base the string can be scuffed as the tension pulls the string (quickly) through the clamp. This is only a very short distance but it can really mess up a string, not only Monogut (ZX)."
This doesn't mean much to me. I hope it answers your question.
Has anyone experienced the massive tension loss of this string that TWU reported? I ordered a set of ZX Pro and would like to try with NG.
It holds tension really well. Better than any poly or nylon string that I've tried. That's for the 1.27mm. Haven't tried the 1.22mm.
Be careful interpreting the numbers on TWU string performance database. The tension loss rubric used does not necessarily correlate to how the string bed will or will not lose tension during play. If you read closely, it states that their measurement of stiffness (dynamic stiffness) is the key measurement upon which all others depend. I don't want to repeat myself too much. Some of my other posts explain how this characteristic of dynamic stiffness makes ZX a unique string.
As Torres has attested from his playing experience, Monogut ZX maintains tension very well during play.
Question for Julian:
With Kevlar mains and ZX crosses, I am not noticing any surface coating that other posters have mentioned. Is there actually a coating, is this string indeed a true monofiliment, so that wear at the surface does not expose a different material?
At the risk of saying too much and getting myself in trouble with the bosses, the string is a true monofilament (you can tell just by looking at a cross section) with an invisible coating!
+1 for the comfort
I'm got about 16-18 hours (and one month) on the Monogut ZX string beds. Both the hybrid set and the full set are waaaaaay more comfortable than my (limited) experience with co-poly or poly strings. Even after one month.
My progression has been: shoulder surgery, full beds of Zyex multi strings (mostly the older Ashaway Dynamite 16g and 17g), then Klipper Zyex, then Zyex main/syn gut crosses, a few co-polys, now Monogut ZX.
The absolute best ball pocketing was the older Dynamites. It felt like the ball sunk into the stringbed before coming out. I loved that feeling and I loved the control that it gave me. Drop shots and hard serves were both very controllable.
The Monogut ZX doesn't give that same "sinking" feeling. It is definitely stiffer feeling on contact than Dynamite. But not in a "Ow! My shoulder/elbow/wrist" poly and co-poly way. I'm still getting nice spin, I assume from the snapback of the mains.
I don't get as much spin as with poly/co-poly but I'll trade some spin for much better comfort every time. I played a 3+ hr singles match with the full Monogut ZX bed a few days ago. Afterwards I was exhausted but my shoulder felt great.
But I'm having a hard time adjusting to the Monogut ZX with drop shots. All my drop shots are popping up. Any advice?

It has more rebound so your hands have to be softer.
I played with a full bed of Gosen Micro 17 (1.22mm) synthetic gut this evening and I think I might have to revise my view of the stiffness / firmness / softness of ZX. Previously, I suggested that this was firmer than a synthetic but I'm not so sure now that that's necessarily correct.
With synthetic gut, to me it seems as if initially on contact with the ball, it feels quite soft, but the harder you hit the ball more resistance you feel. There seems to be a point beyond which the synthetic gut does not want to 'give' anymore. You eventually reach a 'wall' of firmness the harder you hit the ball.
With ZX, at the same tension, the stringbed initially feels firmer on contact but the harder you hit the ball, the more the string 'gives' and stretches (I think this is what Julian refers to a 'dynamic stiffness'). It's a little bit like a natural gut in that sense though the effect is much more linear and more controlled. You don't really feel that you ever hit a wall of firmness where the string resists bending no matter how much force you put through it. This effect can also be seen during stringing on a electronic machine where the string stretches considerably more (than a nylon synthetic gut) when pulling tesion and the tension head moves further back.
So in terms of stiffness/firmness/softness, its hard to describe and not that easy to make comparisons because the characteristic is simply different to any other type of string material.
All I can say is that, having gone through 8 or 9 sets now (any chance of some free sets Julian? ;-)), its not an uncomfortable string and not one that I can see would any cause any potential arm problems. It's definitely an arm friendly string.
Would be well-earned. You're the world's foremost ZX playtester.
I bookmarked this post. It has been a few years, but I finally got you on record as admitting OGSM is stiff. Thank you, another check off the bucket list.
I've always been of the view that Gosen was stiff......compared to an equivalent gauge rubber band!
Update on the kevlar/ZX:
Still playing firm with nice control and spin on groundies and terrific precision on volleys after ~15h of play. The 18g Kevlar is starting to show some wear, but the ZX is still smooth. Strings still snapback and align with no signs of sticking. No deterioration in performance since the tension settled in after the break-in period.
I think if Ashaway were to sell this as a kevlar/ZX hybrid to target higher level non-pro players currently using poly (but wanting control and spin performance that lasts for many hours), it would be revolutionary product.
Wow. That is impressive. Can you think of any reason why ZX would not perform so well as a cross for gut mains (if the tension is got right)?
I'm going to have to try that combo. Trav what would you suggest for tension in a 98, 16x20, 340 gram, 320 SW stick?
For gut with ZX, I think it will depend on how the gut interacts with the ZX surface. Torres reported noticeable change in surface characteristics with wear in full ZX bed. But I have not noticed any change, and this is after 15h plus the 2-3 h before I re-strung the frame with the same set of string.
I think that kevlar, being a porous braided material, is softer and more compliant than the ZX surface, so if anything, it may be polishing the ZX and keepinng it smooth (I notice the same thing with kevlar/poly, where interstring sticking never happens).
As for tension recommendation for kevlar/ZX, I don't even know what reference tension to string my own frame (since I'm playing with the twice strung strings). I would start with 55-60 lbs. It will play like a board initially (which you probably won't appreciate) and then it will take about 4h to break in. Expect the spin potential and power level will increase noticeably during the breakin period.
My litmus test for knowing when the stringbed is too soft is how well I can control volleys against heavily spun drives. I don't mind softer stringbed for serves or topspin groundies.
ZYEX MONOGUT 1.30 after 10 weeks
Installed as a cross @ 56,mains @ 58lbs 1.20 mm poly. Used indoors by a lefty 5.0 Middle States player. After about 25 hours of indoor play, the poly mains broke.. The ZYEX did not show any notching.
I found this to be the case in my personal pair of ZM/poly & poly/ZM frames, but I wanted a player who normally burns up the crosses in string beds to give it a tougher test.
I think gut is similar in the mains. We'll see how it goes.
OK, thanks. Nice that kevlar is relatively cheap.
This is an excellent explanation of how this string performs. You seem to be getting a good understanding of its unique properties.
Unfortunately, I cannot use this forum for promotional activites including the offering of free string.
So after reading thru this thread, may I conclude that ZX should mainly be used as a cross? May I also conclude that one can string this like a syn gut tension wise, rather than dropping the tension 5-10%?
I like the Monogut ZX both as a full bed and as a cross in a hybrid set. In my racquet with a full set of ZX I'm still getting mains snapback after 20+ hours of hitting.
I have used Zyex for years and I always string it at a lower tension than I would a syn gut or a multi. I currently have Monogut ZX at 50# and for the next set I'll try 52#.
And I'm not a string breaker which seems to be an important point in this discussion. So for me the ZX gives the spin mechanism of poly with the arm comfort of the dynamic stiffness identified by Torres and Julian.

what are you hybriding it with? pretty useless comment unless we know that...
I've gone through about 10 sets of the 1.27mm and would make the following comments:
* It's a unique material unlike anything I've played with before. It's not poly or nylon or natural gut so put aside any preconceptions.
* It's a comfortable string even though it doesn't obviously seem soft out of the packet. The string will stretch more than poly or nylon when pulling tension during stringing.
* Be careful when tying off knots. The string can become brittle and prone to breakage in the area where its done 360 degree bends over the X,Y,Z axis ie a knot. Do not worry about over tightening the knot or really cinching it down into a tiny knot. Be careful not overpull the on the second loop when tying off. Do not be brutal when tying off a knot like you might with a poly.
* If you should break the string when tying off, its not the end of the world. I've never broken the string when tying off mains, but have on the crosses. If so, just lose the last cross and tie off on the next available hole. It still seems to play okay.
* Stringing at too low a tension can result in balls flying and the stringbed feeling like it doesn't have sufficient control. Optimum tension obviously requires some guesswork and trial and error, but personally, I would err against going too low. This string plays at it best when you get the tension exactly right for your racquet / playing style ie not too high, not too low.
* Ashway suggest a tension 10% lower than the equivalent nylon but I think that's slightly low. The optimum tension obviously requires a degree of trial and error based on the racquet and particular player, but I've found most success stringing the 1.27mm at the same sort of *normal* tensions (ie no low poly tension experiments) as I would with a 17 gauge soft co-poly, or at a fractionally higher tension, even though its nowhere near as stiff as a soft co-poly. For comparison:
Genesis Black Magic 17 - 52-53lbs CP (full bed)
Tourna Big Hitter Blue Rough 16 - 53-54lbs CP (full bed)
Tourna Blue Hitter Blue Rough 17 - 54-55lbs CP (full bed)
Weiscannon Silverstring 1.20mm - 50-51lbs CP (full bed)
Ashaway Red Monogut ZX 1.27mm - 53-54lbs CP (full bed). (56lbs CP started feeling a bit low powered and slightly boardy but not uncomfortable)
All strung on the same electronic constant pull (CP) machine (Wilson Baiardo) in a Wilson BLX Juice Pro (96sq" / 16x20)
* Ashaway say that the red is slightly stiffer than the natural but I found this to be only marginal.
* The string seems to play better and settle down after an initial breaking in period comprising some ball hitting so allow for that if necessary.
* Would suggest a long playtest to get the best sense of what this string is about, maybe 7,8,9,10 hours plus. You can tell what a poly or nylon is like in the first hour. This string is a bit more unusual.
* Personally, I wasn't bothered by having the slowest pull setting when stringing. It seemed to take out some of the crispness though Ashaway say that slower pulls may result in improved stringbed consistency.
* The string works well as a full bed IF you get the tension right and string it consistently. It also seems to work exceptionally well as cross with poly mains if you're wanting a bit more power, comfort and feel from the stringbed (though note that this playtest is a fullbed ZX playtest).
* Tension maintenance is very good - better than poly, better than nylon - so allow for that.
* I haven't tried the 1.22mm so can only comment on the 1.27mm.
Some quick reviews, all strung in a Juice Pro (96/16x20):-
Full Bed Gosen White 17 (1.22mm) @ 58lbs LO
- Probably over a year since I played with a full bed of synthetic gut, but what a plush feeling stringbed! Comfortable yet with a degree of crispness to it the more you hit through the ball.
- Stringbed results in a fairly flat ball trajectory compared to a poly but it was a fun hit.
- Interestingly I had two matched racquets strung with this and was hitting with a friend whose game I know pretty well. Normally, he'd be hitting more winners (with this favored string of BBO) which produces a heavier ball that tends to zip through the court, but interestingly he wasn't really able to do that with this string. The balls that he was hitting just didn't seem to skip through the court in the same way.
- We looked pretty good though constantly hammering balls back and forth with a low trajectory over the net, with the same racquets and same strings, with neither of us being able to get the upper hand. Surprisingly controlled and a nice hit, but nylon synthetic gut simply doesn't produce a particularly heavy ball off the ground compared to a poly. The movement of the ball was just more predictable and balls seemed easier to return.
- The major downside for me was that on the 2nd outing the strings had just turned to crap in terms of tension loss, and were moving about in the stringbed, sticking and not returning to their original positions. Control had really deteriorated and the strings seemed a bit powerful with too much length on the ball compared to the 1st outing.
Full Bed Brown ZX 1.27mm (actually its more like a straw color) @ 56lbs CP
- I'm starting to think that the tension for ZX is like baby bear's porridge - its needs to be 'just right' to get the best out of it.
- This tension seemed a bit high and I wasn't finding the same sort of punch through the court as I was at 53lbs. Sweetspot also felt a bit smaller and not quite as forgiving as I remember the Red ZX to be (though that was strung at 53lbs CP). Quite alot of 'bounce' from the stringbed at this tension of 56lbs CP and quite a high trajectory of the ball off the strings at this tension.
- Not convinced that there's a massive stiffness difference between the red and brown. If there is a stiffness difference, I'm guessing its marginal. That said, I do wonder whether the strings plays slightly differently....
- I'm also inclined to think that the strings need time to settle down or have a break in period post stringing as a full bed as they seem to play better on their 2nd or 3rd outing.
- Tension maintendance / consistent stringbed stiffness is pretty exceptional. There simply doesn't seem to be the rapid tension loss with this string as you would get with a nylon string or a poly.
- Maybe its the higher tension throwing my perception off, but the brown 'feels' like a slightly thicker gauge compared to the red.
Pacific Polyforce Extreme 1.25mm / Red ZX 1.27mm @ 52/53lbs CP
- The Pacific poly dominates the feel of the stringbed at this tension. Feels very much like there are two different stings in the stringbed (unlike Black Magic / ZX where the characteristics of each string seem to blend better with each other). Would possibly need to have a wider tension differential next time, with the ZX at a probably a higher tension or the Pacific slightly lower.
- The Pacific plays a bit like a more usable version of Luxilon 4G. Not quite as stiff as 4G but in terms of stiffness its still pretty much up there. Nowhere near as soft as Black Magic.
- Not hugely bitey but the Pacfic makes the stringbed very precise in terms of directional accuracy when hitting the ball and aiming for spots. Probably the stand out characteristic of this poly. ZX adds some softness and power, but its very much in the background in this hybrid at these tensions.
- The stringbed seems settle down and strings blend a bit better on the 3rd outing as the poly loses a bit of tension, as the expense of some crispness and directional accuracy. The Pacific strikes me as poly for a big hitter - stiff, directionally precise, controlled, though not necessarily that easy on the arm.
Black Magic 17 1.23mm / Red ZX 1.27mm @ 52/53lbs CP
- 2nd set of this hybrid.
- Plays very well. The characteristics of each strings blends with the other very well.
- In performance terms, same comments as previously
- I may go fractionally higher in terms of tension next time; the tensions just to be adjusted to the particular racquet, playing style and conditions.
Full Black Magic -v- Black Magic / Red ZX Hybrid
- I guess it depends on how you play. As much as I'd like to say that I hit 20 aces per match, hit Federer-esque laser like winners with every stroke executed perfectly each time, I simply don't. The reality is that is my sort of level, matches are generally won by grinding, playing the percentages well (or at least better than your opponent), having a slightly better strategy and relying on a mix of forced and unforced errors. Thrown in an uneven bounce from court and a bit of wind, and I have to say I probably prefer the control of a full bed Black Magic setup, and the greater topspin that it offers (percentages and margins in my mind) even if its an the expense of some power and even if it only lasts about 5 hours before going dead. It's a tricky one, and very much a personal preference - I'd like to try a BM/ZX hybrid at a higher tension to see what that's like before coming to a final view. I think if you have a lower powered stick, or you simply want to add some power and forgiveness to the stringbed, or soften up a poly stringbed, ZX would definitely a good choice to add into the stringbed.
Torres - just a suggestion, if you hybrid the MZX with Gosen in the cross you might be able to get a crisp and comfortable set-up that will allow you to really go for those shots and keep the string bed lively.
This is exactly how I describe Black Code 18. A remarkable characteristic, one that I've never felt before or since.
Thanks for the suggestion. It would be an interesting combination. If I had a racquet that was less of a tree log, it would probably be something that I would try. As it is, a slightly lower powered, more spinny, all poly setup tends to be a slightly better fit for the Juice Pro. I may try it another racquet though.
Just saw this new page on the Ashaway site: http://www.ashawayusa.com/Polyketone7.php
John Gugel is touting ZX.
Stringing this on a Klipper
I tried to string the red zx on my Klipper yesterday -- I was really looking forward to a ZX/Poly hybrid trial. Anyway, it broke twice, in different locations each time. So, I am out of the red ZX, but I have another pack of the natural.
I was attempting to string it at 53lbs (though I haven't ever calibrated). I suspect that I need to back off on the clamps, though they aren't leaving indentations. I am dropping it slow and taking multiple drops to get the stretch out.
One break was in the middle (1 or 2) at the throat while I had clamped out at 6's -- everything was static and it just popped. The other break was during the static part of a pull (weight was not moving, just hanging on the string) and a higher up, but in the throat clamping area.
Any advice on what to do to give me a better chance of a successful deployment would be welcome. Stringing this is certainly not fun -- it better be damn good!
I've also found that this string is very tricky to install. When I tried it first with a full bed, I succeeded, but because of the extreme movement and stretch I always had the feeling that I was just a sneeze away from snapping the string while I was doing the mains.
But when I installed it solely as a cross (with kevlar mains), I didn't seem to sense the fragility as much since the the mains prevented the tension from extending very far along the string -- it was a much smoother process that didn't require multiple drops per pull (except that I left my guard down at the end and broke the string when I tried to pull tension on the final knot - luckily the first half the knot held fine).
So my recommendation (unless you want to punish yourself with frustration) is to use it only as a cross. BTW, my kevlar/ZX hybrid is still playing great after 17+ hours of play.
Thanks for your stringing notes Trav. 17+ hours is pretty great. What's the longest you've ever been satisfied with the performance of a kevlar/copoly job?
I had been playing with kevlar/poly for several years without paying much attention to stringbed deterioriation. But once I started paying attention, I could see performance start to drop off after 3-4 hours. I'd say the kevlar/ZX is playing as well now as a kevlar/poly plays within the first 2-3 hour window of nice playability, with similar type of ball response. There are subtle differences -- I'd say that the surface of the ZX is not quite as smooth as a really smooth poly like PTP. It's also less smooth that SPPP. It's surface is more akin to Silverstring (which is less spin-friendly). The spin response is similar to kevlar/silverstring, but the feel is not as harsh, and the power level is higher for a given crispness level. I prefer the overall playability of the kevlar/ZX to kevlar/silverstring.
Thanks for this Trav. Before winter hit I was using gut/silverstring. I also found it to be not quite as slick as other polys.
The TWU friction CoFs for silverstring: 1.08 and ZX: 0.88, SPPP is 0.98
Your experience suggests that maybe ZX has a coating and that the undersurface is not as slick as the testing suggests, or, the surface of ZX is softer than Silverstring and SPPP and gets worn more quickly. I wasn't able to decode Justin's cryptic reply to your question about coating. You don't happen to have a powerful microscope around do you?
Have you noticed any denting of the ZX crosses? After 17 hours are your mains getting stuck out of line at all?
Just saw this latest update. I think you're getting string playtest fatigue. Ultimately all the equipment tweaking is just about the margins, I suppose, so if full copoly and slightly less power helps you with control and consistency, there's the margin.
But yeah, I think the whole point of ZX is to add a little extra pop, a little extra forgiveness, or maybe a significant improvement in comfort when compared to a full bed of copoly. It also sounds like it would be perfect for a player that isn't swinging 60 mph or more on their groundstrokes; for those players copoly is simply a waste of time.
My interest in ZX is twofold: I want as much arm-comfort as possible to protect against injury. And I want more pop, on serve in particular. I was playing at 5000+ feet for the past three years and my serve was (kinda) monstrous at that altitude. Now that I've come back down to earth (sea level) I've learned that altitude naturally gives more speed but takes away some spin. So now my serve is slower but spinnier (I'm also playing on slower courts now, magnifying these changes). Copoly is only going to make that worse. Gut/copoly helps, but I'm hoping that gut/ZX will give me the extra pop I miss, and I don't mind if I lose a little spin as I'm getting more now, regardless of string type, than I was at altitude anyway.
^ Absolutely. String choice is definitely player and racquet dependant. I have a beefy stick (346g BLX Juice Pro), so something that tames it's power and adds control will tend to suit slightly more, particularly when you throw in windy conditions, uneven bounce off the court, non-pro level stroking consistency etc. In a different or lighter stick or stiffer stick, I'd lean more towards a more powerful stringbed or softer stringbed which is where ZX comes in useful.
At 19+ hours now (not including the 2 hours at lower tension with the same string), and still playing great. If anything, the surface is smoother now than when new. No denting at all. The mains are still laser straight and perfectly aligned without needing to touch them - silverstring doesn't get this smooth. Really enjoying the crisp control.
Sounds awesome. Can't wait to try it with gut mains. Will probably also try kevlar mains given how flexible ZX is.
First rating from stringforum: http://www.stringforum.net/ratings.php?sdnr=4978&fstatus=0
Never mind me, just continuing to hype the ZX.
i'm just about to jump on this zyex train myself. got a set of monogut zx in natural waiting to be strung. i had a hard time deciding what to do with it, that is either playing full bed or going my usual hybrid way. i basically have played for the last three-four years mainly poly mains / sgut or multi crosses, with few exceptions, so in the end i decided to go the hybrid way, nevertheless, "encouraged" by torres reporting that the string plays like a soft poly, i'll put the first half set in the mains, crossed with my regular mcs.
i intend to string at my regular tensions, that is 21kg mains (~46lbs) and 21kg crosses.
putting a poly in the mains and the zx in the crosses is an option for the second half set, but i am rather reluctant to go this way, for no other reason but not having a good feeling about it. maybe after experiencing the zx mains i will eventually change my mind, but for the time being this would only be my "second option".
i'm rather inclined to pair it with a halfset of natty gut i have at hand (no premium gut but signum pro cross-gut 1.30), but then again i don't really know which way to go. natty mains or zx mains.
i have played last summer a hybrid with signum pro firestorm 1.25 mains and this cross gut 1.30 crosses and was really impressed by the durability i got out of the crosses, which lasted for 8 hitting hours. i had to go through two sets and both really held up absolutely impressively, so i decided to buy a set of this gut, admittedly to try it in the mains, as so many posters rave about ng mains / poly crosses. as i am a stingbreaker i'm afraid this will be a short-lived experience, but i think i'll give it a go, what the heck.
Keep in mind that Torres did not care for ZX mains/copoly crosses but very much liked it the other way around. ZX seems to excel especially in the crosses. Travlerajm is really digging it in the crosses with kevlar mains.
To my mind it sounds like the ultimate cross: it's more flexible than any multi or syngut, so if you hybrid copoly with one of those in the crosses to find some comfort, ZX will give you more of that. And unlike syngut or multi, it's very slippery and smooth, so it acts somewhat like a copoly cross in that it frees up the mains to slide and snap back.
With the gut I would go with gut mains/ZX crosses, but I'm a gut/poly guy. Since you had a positive experience with copoly/gut maybe you'd like it. But the ZX does not return energy like natural gut does, and I think you want that energy return in the mains for spin, which is also why it may not be as great in the mains with copoly crosses.
But follow your gut! Whatever you try, I hope you like.
