    Sorry. Busy weekend.

    I would like to weigh in on Torres' observations and the resulting discussions. First, I need a better understanding. The points I have taken from the posts on this thread are:
    1. Monogut ZX is mainting tension.
    2. The power and comfort are both lasting.
    3. Control is not problematic.
    4. The strings are not moving.
    5. There is a decrease in playability after playing for hours that can best be described as a loss of spin.

    Torres: Is my summary accurate? Are there any other definable characteristics to this decrease in playability other than the loss of spin?

    Yes, that's a pretty acccurate summary.

    I have to say that I absolutely love the feel of this string during the first few hours. It has an incredible combination of crispness and plushness - unlike any other single string that I've played with (and I've played with a lot!). Red ZX has most of the control of a full poly bed, the power of a multi, and almost the feel of natural gut all rolled into one, but with none of the changing tension loss issues of some of those strings. It's an absolutely sublime combination of characteristics. The closest thing I can compare it during the first few hours play is a Wilson Natural Gut 1.30 (M) / Alu Rough 1.25 (C) hybrid. Obviously its not quite at that level but its in that ballpark - it really is THAT good in terms of its combination of feel and the confidence that it gives.

    That alone puts me in two minds as to whether I should keep a spare racquet strung up for drills or recreational play despite ultimate performance not lasting as long as I would like.

    1. Tension maintenance is exceptional during the time that I played with the string. Unlike a poly or a nylon, I could detect no discernable loss of tension that affected playability.

    2. Power is excellent. Just about the right amount. Not overpowered or underpowered - very controllable 'volume knob' power characteristics. Comfort is exceptional. I feel absolutely no wear or fatigue on the arm, shoulder or body at all (though I come from predominately a poly background). It's put the fun back into my tennis again since I don't feel as much fatigue on the body the next day.

    3. Control is not problematic. Control is actually very good. You can confidently take huge rips at the ball and yet also play the most delicate of touch shots. Aided considerably but the amount of feel that the string provides. Absolutely lovely balance of crispness and plushness.

    4. The strings don't move. Not in the racquets that I strung it in anyway.

    5. There is a decrease in playability after playing for several hours that can best be described as a reduction in the amount of spin that the string can impart on the ball.
    - This is the sticking point for me, and the thing that stops me from throwing away all my other strings and buying reels and reels of this stuff. In outright performance terms, it doesn't quite provide the ultimate in outright spin performance that a freshly strung poly would provide, but its performance is high enough and its superb blend of other characteristics are enough for me to live with that.
    - The problem that I've found that after about 5 or so hours of hitting, is that I notice the characteristics of the string have changed in that its harder to impart the same amount of spin and 'heaviness' on the ball as during the first few hours. At 6-8 hours in (and I've hit with the strings for a couple more hours since my last post) the strings feel slightly more tinny (though never uncomfortable) and that ultimate degree of spin orientated performance isn't there anymore. Obviously there is still some spin, but its a bit like a poly that's been bashed around too much and lost its best (initial) characteristics though with ZX that loss is not as marked or as extreme as that of a poly going dead. However, its noticeable to me.
    - I'm not really noticing any significant loss of other characteristics though if I was splitting hairs I might say that there's a very marginal loss of power and strings feel marginally more tinny. To me it feels like how the characteristics of poly might change when they've bashed with a ball hundreds and hundreds of times, though the change is more gradual and not quite as extreme.
    - Its still perfectly playable after 5 hours, but I would be using it primarly for drills or social play after than time rather than tournament play.

    Appreciate you taking the time to join this thread though Julian and also to 'corners' for keeping this thread alive (I would never have tried ZX otherwise). Absolutely lovely string Ashaway have got in (red) ZX 1.27 - unlike any other - I just wish that its ultimate (primarily spin based) performance lasted a bit longer.

    Thank you, Torres, for the in depth explanation. The decrease in the ability to impart spin on the ball is an interesrting observation. String movement or tension loss would be an easy explanation. Since you are not experiencing either, my best guess (and this is just a guess) is a change in the integrety of the string surface itself from repeated contact. Are you a heavy top-spin player? It is unlikely that you would be able to see any change in the appearance of the string (I'm sure you would have reported it if you did). As you know, Monogut ZX is a very smooth string. Also, Zyex has a higher friction coefficient than poly, which makes it more susceptable to nicks and scrapes - one of the reasons for the detailed strining instructions we provide. I am wondering if this susceptability to friction is affecting the surface as you play and changing your ability to control spin. Of course, it could be something completely different.

    Do you have access to a microscope or magnifing glass? If you do, I would recommend looking at the string from your hitting zone magnified and compare to the same magnification of unused Monogut ZX or some from the outer areas of the racket where your don't make much contact. Just an idea.

    Interesting hypothesis Julian. From various descriptions of Zyex that I've found it sounds like it is, as a material, quite abrasion resistant. Do you think, though, that it is not quite as good as a slippery copoly in this respect?

    If your hypothesis of surface scuffing were on target, it would seem that pairing it with natural gut mains would be boon, as TW University testing has show that gut mains with crosses that are at all slippery results in a pairing with lower coefficient of friction than either string strung as a full bed.

    Also, would you care to weigh in on the widespread theory that loss of elasticity or resilience is responsible for the perception that a string, particularly a poly, has "gone dead"? TW University tests for tension loss, dynamic stiffness and energy return, all of which seem to converge around "elasticity" but none of which define it. In physics terms, I believe elasticity is defined as the slope of the stress/strain curve. So a loss of elasticity would seem to be a change in the shape of that curve and I haven't seen any studies that have attempted to document such a change. So at this point it seems difficult to objectively evaluate claims that a string has lost elasticity along with lost tension. Has Ashaway quantified elasticity and elasticity loss?

    Torres reports that his strings have not lost tension, but I'm not sure if he's established that objectively with a stringbed stiffness measuring device. It seems, given your earlier statement about ZX not changing in stiffness much as it loses tension, that it may feel as though it has not lost tension but in reality could have done. With a poly string, by contrast, the dynamic stiffness drops off in proportion to tension loss, so it's quite easy to tell when strings have elongated as a result of repeated impacts or the passage of time.

    I believe Elasticity and Dynamic stiffness are the same. Elasticity is a strings ability to maintain its elongation (or stiffness) after being stressed or stretched out. For example, Nylon streches quite a bit (has a lot of elongation)(is not very stiff). However, after being stressed, it becomes much stiffer (has less elongation)(is not as stretchy). Zyex also stretches quite a bit. After being stressed it does not become as stiff as Nylon. The measure of a strings ability to maintain its stretch (elongation)(lack of stiffness) is elasticy (dynamic stiffness). This is the reason Nylon loses tension fater than Zyex. The more a string stretches and does not return, it actually gets slightly longer resulting in the loss of tension. Thus, Zyex holds tension better than both Nylon and Poly.

    As for your first question, it remains to be seen how the abasion properties of Zyex compare to those of Poly in Tennis play. I would suspect that niether present a problem. However, I am reaching for a reason to explain the observations of Torres about loss of spin. Spin is much more related to the surface of the string than the elasticity. You want something to grab the ball. As you mentioned, the contrast created by Hybrid stinging is probably good for this.

    Right, I think I've figured out what's going on with this string! Had a close look at this string and also a couple more hours hitting. Report to follow.

    Thanks a lot for your thoughts Julian, and thanks for contributing to this thread!

    For a long time I had assumed that dynamic stiffness and elasticity were more or less the same. Therefore, it always puzzled me when people would say that "dead" poly would start hurting their arm. As string lose tension they lose dynamic stiffness. Less stiff strings should be easier, not harder on the arm. So a bit of a mystery. We know from some research done in Japan that strings that slide and snapback transmit less shock to the arm than strings that don't, apparently because that sliding and snapping back increases total dwell time. So that is one way to explain the arm-busting nature of "dead" copoly strings - if the strings are no longer able to snapback they may start transmitting more shock, even if they are less stiff (due to tension loss) than they were at the start. So then the question becomes, why are they failing to snap back. I thought the answer to this question was pretty simple: as strings lose tension they lose stiffness and therefore store and express less energy. So strings that have lost tension, may, because they are now less stiff, slide and stretch too far sideways and then not have enough energy stored in them to snapback. But, several posters have pointed out that copoly strings strung at very low tension (<35#) snap back just fine. So then the question becomes: what is the difference between a string freshly strung at 35# and one that was originally strung at 50# but is now at 35# due to tension loss? Previously, my hypothesis of choice was damage to the string, either notching or the type of abrasian and scuffing that you mentioned in an earlier post. Either would increase interstring friction and prevent snapback from occurring with the desired effect.

    But some some posters have suggested that natural gut, being very elastic and maintaining elasticity very well, will still snap back even if it were rolled in the mud. So there is the second hypothesis, and the one held up by many people who talk about poly "going dead" - that if a string has lost elasticity it won't matter if there is very little interstring friction, that string won't have the energy to snap back, which would explain the observed difference between 35# freshly strung and 35# as a consequence of tension loss. I actually think this is a pretty simple research question. At present, both USRSA and TW University test dynamic stiffness and energy return after they have subjected a string to a tension loss protocol involving repeated impacts and a short passage of time. If dynamic stiffness and energy return were measured prior to this testing as well, I think it would then be possible to objectively compare a string freshly strung at 35# and one that got there after losing tension.

    Anyway, I see Torres may have another hypothesis to advance (above). Still very intrigued by this string and I hope more players will catch onto it.

    Julian, What are the recommended stringing instruction for Monogut ZX Pro?

    I wait at least 5 seconds before clamping the string? Someone suggested longer. Also What is the recomended tension? It's stated that MGZXP should be strung 5-10% lower than normal, similar to what poly is recomended to be strung at.

    I can give you the 10 tips for stringing Monogut ZX / Pro that are now included with each set. Any sets that left the factory before December would not have these instructions.

    1. Don't pull knots too tight.
    2. Don't scrape or nick string. Be careful when using a starting clamp anywhere on the string.
    3. Allow time for string to elongate under tension. Count to ten (10).
    4. Use slower tensioning speed on electronic machines. Fifty (50) % suggested.
    5. String with at least 10% less tension than nylon strings.
    6. Don't apply over 60 lbs tension.
    7. For poly players use prestretch for muted response.
    8. Be careful with sharpe tools.
    9. When using double action clamps release the base first.
    10. Check the racquet grommets for excessive wear.

    Yes! Poly that started at 50 lbs but ended up at 35# has lost all elasticity (dynamic stiffness). It cannot return any energy to the ball. Your arm has to do all the work. Poly at 35 lbs freshly strung still has some elasticity to return energy to the ball. Plus, you have created somewhat of a trampoline effect by stringing it so loose. Natural gut and Monogut ZX have much more elasticity (dynamic stiffness) so they naturally return more energy to the ball. The more work the string does, the less your arm has to do. This is the reason that on Tennis Warehouse University string finder that Monogut ZX ranks only behind natural gut products in arm friendliness.

    I played for a couple of hours last night (hitting hours 8-9 hours with this string) in practice matches with the mens team and I was just on fire. Not sure why but flat serving with this string was just amazing. I could just smack everything. Either I was playing well or the string was giving me so confidence that I started hitting 2nd serves as 1st serves. Two different opponents said, "No way is that a 2nd serve" and "Whoah, that 2nd serve!". You just can't lose when you can't be broken.. Maybe the stiffer stringbed helped with that, but the confidence I had to hit really hit out on serves without fear of it going long was amazing. Length on serves unbelievably consistent. On groundstrokes though, the touch and feel of the string wasn't a good as during the first few hours. Stringbed felt stiffer. Still playable though.

    Hitting hours 10-11 or thereabouts with this string this evening. I definitely think that this string has gone a bit dead. Stringbed feels stiffer, not as plush as during the first few hours (or even last night) and with less power and forgiveness. Stringbed is definitely not feeling as nice. Flat serves were okay, but I just wasn't the feeling the same confidence on groundstrokes, though fatigue could also have possibly been contributory factor. I'm certain the stringbed feels stiffer, and that spin and heaviness of ball isn't really be produced in the way or the amount that I would like. It crossed my mind for the first time this evening (11th hour of hitting), whether or not I should cut out the string from the racquet.

    As suggested by Julian, I had a look at the string surface very carefully. Basically there seems to be notching of the mains at the intersections of the mains and crosses. Basically, there's a dent or divot in the mains where they've intersected with the crosses. When you move some of the strings they slide back but not exactly into their original positions ie the position where the original 'dent' was in the intersection of the strings.

    You can see this in the picture below - I've pulled the top cross down and whilst it springs back it doesn't quite spring back into its original position (where the dents are on the mains immediately above the top cross string in the picture). It needs help to 'slot' back into place into those and when you do that you can physically feel the string drop into the dent originally created. Clearly the strings aren't sliding or 'snaping back' as well as there were originally.

    [​IMG]

    Using your fingers to pull the mains back and forth, and some of the mains make that 'clicking' or 'cracking' sound a bit like when you have to move a nylon/multi strings back into place after they've moved. Rather oddly when you pull some of the mains backwards and forward so that they rub against the crosses, they a sound like a violin - 'eeeeeek', 'eeeeek'. It mostly the mains away from the cetnre sweetspot where the string spacing is greater. It's very odd. Pulling the mains backwards and forwards 10 times or so and the sound disappears, as does the 'clicking' and 'cracking' sound. String feels a bit more pliable as a result. As odd as it may sound, it makes me want to give some of the mains a massage with my fingers by pulling them backwards and forwards a bit.

    Pulling back the mains, some of the intersections have abrasion across surface of the cross string where the mains have repeatedly rubbed backwards and forwards against the cross. In the picture below the blue pen is pulling apart the two center mains to reveal the abraison on the cross string underneath the main string where they intersected (see immediately to the left of the blue top of pen). The string is usually very glossy, an oily gloss, but the area where they've rubbed is very matt and there is abrasion where the surface of the cross string has worn due to the repeated sliding backwards and forwards of the main against it.

    [​IMG]

    I'm surprised by the amount of abraison in that particular area because that's the top cross string and I wouldn't have thought (though I'm no expert on this) that the mains would be moving/snapping back so much against the cross string right at the top of the frame. I guess those center mains must work pretty hard. I'm not one for gimmicks but it did cross my mind whether a spot of silicone lubricant in those areas would help restore performance.

    So it seems that that the sliding and 'snap back' ability of the mains seems to have reduced and they don't move as well due to some notching and abrasion when the mains/crosses have rubbed against each other. When you move the mains with your fingers, they seem to move in stages now rather than one fluid smooth slide, which I guess what the string would have done originally when fresh(er). From my experiences, performance drop off with this string is a bit like a poly except its a much more gentle decline with the string remaining playable during that decline.

    Question for Julian - does this string have a coating? If so, what's the purpose of the coating? It seems that the string is normally glossy but where the strings have rubbed against each other, the string has lost its gloss and turned matte. Is there anything that might be likely to be making it not as a slide/snap back as well as it originally did?

    I think it would. And this is a way to confirm the notching/scuffing/denting hypothesis. You could spray the whole bed and if spin returns to "fresh" levels, you've got it sussed.

    I think there's something quite unique about this string, a certain special je ne sais quoi. My points percentages have been really quite high with the string. I do wish peak performance lasted a bit longer, but I think I'm going to get another couple of sets and see how it performs in a couple of tournaments I've signed up to in April. That's going to be the ultimate test.

    I'm not quite convinced it has the ultimate performance of a freshly strung poly but it does have a certain indefinable 'something' thats begs to be properly tested under competition conditions.

    I think I'm going to string up a different racquet with ZX as a full bed, and restring the Juice Pro with a ZX/poly hybrid to see how each performs. I think I'm also going to get a set of Natural 1.27 to see it compares to red.

    My only other gripe at this stage is that I wish this string was cheaper (or at least reels were cheaper). Unless someone tells me that the natural ZX lasts alot longer than the red, I think the price is just a touch high given that you could get 2 sets of say Genesis Black Magic (3 sets from of a reel) for the price of one set of this with those 3 sets providing comparable longevity based on restring every 5 hours (assuming that you re-string yourself and therefore don't incur stringing costs).

    It's an intriguing thought. It would be great if Ashaway could invent some spray that would allow you to re-lube or re-coat certain spots. I guess it might be a bit tedious though to pull away indivdual strings to get to each intersection though.

    Hey folks, i just read the first 221 posts. Good stuff. Can anybody point me to a review for this string as a cross for gut mains? Thats my main interest here, thanks!

    If lubrication can make ZX's playability last longer, then mixing ZX and natural gut might be the way to go (i.e., if we subscribe to the theory that natural gut releases oil to keep string-to-string friction minimal).

    But if the performance of ZX only lasts a few hours, then it might serve as a good substitute for gut in a gut-poly hybrid.

    I don't think you have to lift and pull away strings to get to the intersections.

    Just spray and hit. Then the string's own movement and snap-back will probably lubricate those intersections.

    Just a guess, though.

    10 hours cut out time, wow! That's mighty impressive for any monofilament string.
    This basically means it will remain playable until natural or synthetic gut mains break.

    Without giving away any trade secrets about how we make the string, I will say that your idea in the previous post of putting a silicone lubricant on the strings to increase the longevity of the spin related playability that you seem to have lost is a good one. I would be really interested to find out if that brought back any of the spin potential.

    Don't be afraid to try Monogut ZX Pro (1.22 version)! Very little loss of durability from the ZX (1.27).

    Hello Julianashaway, I have a question for you.

    Why does Ashaway not produce the industry-standard 660-ft-long reels?

    You have half reels and at least for the Monogut ZX the reel is more expensive per foot than the single pack. It would be nice to see full reels with a lower per-foot pricing.

    The string is constructed the same as Mongut ZX. It is simply a thinner gauge. As with any string, when you decrease diameter you trade durability for playability. In the case of Monogut ZX Pro, blind testers have found that it is quite durable. You may find all the characteristics you like in the ZX with even more playability- maybe even more of that heaviness of ball that you like so much.

    I'd be interested to know that as well. If the price (of reels) was lower, I'd be inclined to pull the trigger on reel purchases, rather than holding back.

    I thought there was another one out there, but I can't find it. So the only report I think we've got so far is this one, but the player cut it out after 10 minutes so I'm not sure how much useful info it provides: http://tt.tennis-warehouse.com/showthread.php?t=447979

    I mentioned this previously, but that guy has made every single mistake in the book IMO when 'evaluating' the string. He tries to draw conclusions that I don't think he can legitimately draw.

    1. He shouldn't really be testing a new string as a hybrid, especially when its a string that's made from a new material. You simply can't really tell what string is doing what, let alone know what the correct tensions or the optimum tension differentials between them should be. I can find two strings that play well individually but put together simply do not jive. It doesn't mean either string is bad. Or get the tension setup wrong with the same results. I dislike Weisscannon Silverstring 1.20 in 6.1 95 18x20 but I do like that string in a Babolat Pure Storm Tour. I dislike a gut/Scorpion hybrid but individually, both strings are fine. I hybrid a soft string with a stiffer poly, get the tension wrong on the cross and it will play like crap, even though neither string is bad.

    2. Why hybrid it in the first place? ZX already offers comfort, power and control by itself provided you get the tension right. Why is there any need to add gut, especially in the racquet he has (see below)? You usually add gut gains for power and feel. ZX already has a good amount of power and feel, not as much as natural gut but more than enough to be getting on with. And in any event, most people would use a stiff co-poly to stop gut from trampolining. ZX is not a stiff co-poly especially not at the tensions he's used. It's not far off having a full bed of gut and at the tensions he's used and the racquet he's strung it in (see below), its not going to work.

    3. He's strung it in an extended length, open pattern 100sq incher, which he's leaded up to swingweight of 377g (yep, 377g). A tension of 50/50lbs for gut/ZX in that type of stick is just insane, even more so if that was strung on a crank. I could have told him that that tension wasn't going to work even before he had strung it up. Sampras used to string at close to 70lbs in a 85sq incher. He's 50lbs in a 100sq". I could string a gut/ALU hybrid at that 50/50lb tension in my lower powered, and more control orientated Juice Pro, and the ball would still fly all over the place. Those gut mains would be out of control at that tension without stiff crosses. It doesn't mean that either string is bad - that just isn't a valid conclusion for him to draw IMO. The tension he's used is simply far too low.

    And as you've mentioned already, the coup de grace of 10 minutes hitting is just the final nail in the coffin.

    Hitting hour 12 or thereabouts.

    Red ZX 1.27mm feels a bit dead. Its not unplayable but its nowhere near as plush or as forgiving as it was before. Stiffer than before though not uncomfortable. Not noticing any tension loss that affects playability, just a stiffer stringbed and less power. Not feeling that I have any string advantage. This string now feels like it could be any generic string. Thought again about cutting it out....until I mishit a ball and broke the two mains right at the top of the frame.

    So that officially ends the playtest of this string in the 2nd racquet.

    I have the 6.1 95 18x20 restrung again with Red ZX 1.27mm at 52lbs CP (versus 54lbs originally), so I'm going have a hit with that again (this was the racquet where the string broke at the knot when tying off and its eventually slipped the knot during play, so its been restrung again).

    Will be testing Natural ZX 1.27mm in the Juice Pro at some point to see how it compares to Red (the Natural is supposed to be slightly softer).

    Julian, in your opinion how is the stringbed result / playability different with slower pulls versus fastest pulls?

    Normally, I have the highest pull speed setting simply for speed. The only time I've used slower pull speeds previously was to experiment - it was done using a poly - and from what I can remember, the result was a softer stringbed. Is that the likely result with ZX?

    The industry standard 330' and 660' reels came about in the old days when tennis rackets were much smaller. Individual sets used to be 33'. 330' and 660' reels were an even 10 and 20 sets respectively. Now that Tennis rackets are much larger the standard set is 40'. Ashaway adjusted its reel sizes to 360' and 720' to make the reel an even 9 and 18 sets respectively.

    Generally, Ashaway prices reels at about a 5% price break from equivalent number of sets. When you do the math, be sure to use 40' as the length for the sets.

    I don't know if it will result in a softer stringbed. The recommendations for the Monogut ZX are designed to give a more consistant stringbed. Monogut ZX has 3 times the elongation of poly strings. This extra strech provides more opportunity for inconsistancy in the stringbed because the string always wants to recoil while being pulled. Generally, the slower the string speed, the more consisant the pull. The slight inconsistancy in the stringbed with poly may not be noticable where with Monogut ZX it would be magnified because of the extra stretch in the string.

    Thanks for getting back to me.

    Unless the TW pricing of your products is quite different from your suggested retail prices, here is the breakdown of the pricing of ZX Monogut:

    A single set: $15 / 40 ft = 37.5 cents per foot
    A 360-ft reel: $140 / 360 ft = 38.9 cents per foot

    So, a reel is more expensive than a set. I don't see the 5% price break for the reel here. Nor do I see 720-ft reels.

    Monogut ZX has to be the weakest string ever made. I strung mine at 48lbs and was careful not to overtighten the knot after finishing the mains, but it still broke right at the knot. I took a piece and clamped it in a vise, made a simple loop knot and pulled with pliers. It broke at the knot without much effort. Any bend on the string makes it weak. I bet a hard mishit near the frame will make this string break.

    Sorry. It is not appropriate for me to discuss specific details of pricing or distribution in this forum.

    Which means the retailer is making extra profit on the reel and not passing the savings on to us unless I'm missing something.

    If you read the two RSI blind playtests you'll find that only several people in each test broke the string during installation. Yes, the tensile strength is low, but I think the string just requires special care, just like natural gut.

    I have found that Ashway's reels are not discounted over the cost of nine sets for the Zyex base strings I have used over the years

    Had a hit with the Red ZX 1.27 restrung in the 6.1 95 18x20 this time at 52lbs (versus 54lbs originally). String did not feel nice. Nowhere near as nice as in the Juice Pro. Tinnier than what I remember and I just wasn't getting the control from the stringbed. Stringbed just felt inconsistent and too powerful in terms of court depth. I'm wondering whether this string is tension sensitive, needs break in, and/or more suited to certain sticks/patterns/tensions.

    I've strung gut many times, often in the mid 60's, and never had them break while stringing. I'm not going to use a string where you have to make the knots so slack that they will come loose.

    You don't have to do that, but you do have to be v.careful when tying off.

    Hi Julian, is Monogut ZX suitable for stringing at sub-40 lbs tensions? I have been playing with full poly setups at ~36-38 lbs for the past three years and really like it. There is a very large thread here dedicated to this where people report good results with initially full poly at such low tensions, but recently also syngut and gut (http://tt.tennis-warehouse.com/showthread.php?t=319527). In a nutshell, the idea is that as you go into the sub-40s realm, power no longer increases and may even decrease, while spin and comfort increase, resulting in a very comfortable, spinny and controllable setup. The acronym ELT (extreme low tensions, ~30 lbs) is now gaining acceptance in these circles...

    Have you guys ever tried ZX at comparable tensions, do you think it could work?

    I do not have any first hand reports of MZX or MZX Pro strung at sub 40 lb tensions. It would definately work. Whether you like it or not would certainly depend on the player. MZX is much more powerful than poly. At such low tensions the string is likely to be too lively for most. MZX is also much easier on the arm than poly. The increased comfort you get from low tension stringing with poly may not be necessary with MZX. Of course, all of these staements are also true of natural gut. A very good player who knows how to control his or her ball and is looking for maximum comfort and control may like these extreme low tensions with MZX. The best advice I can give is : If you like natural gut at these extreme low tensions, try it.

    Thanks, your advice makes perfect sense.
