Revisiting Monogut ZX

It gets pretty bad. I have to have 7 rackets of the same make and model, different lengths of rackets, weights and string set ups. Fortunately I can find this make and model of Prince Classic Graphite 100LB from 20 - 60 dollars. These rackets don't include "yesterday's" late great rackets or my very minor collection of thrift store rackets. I have a box full of reels of string but the only reels that get used up regularly are Ashaway Kevlar and Zyex Pro. My regular UPS guy kids the new guys training with him that I string rackets for pros who send me their rackets.

I blame it all on getting a Prince Neos 1000 3 yrs ago this coming June.
See what I mean.......? I would be in the basement under the single hanging electrical wire with a 40 watt light bulb ( all I could afford because of buying so many sets and reels of strings) above me shining down flickering on and off as I mumble to myself "string just one more racquet and I can quit. This is my last one...." As I laugh in a low hysterical sleep deprived manner.
Yeah graycrait you can quit any ol' time you want.

What tension did you string the ZX? What tension do you run the Dynamite?
Sorry, I did not see this thread reply question until today. I use 48 lbs with the Dynamite. I used ZX at probably 55lbs. My gut mains are always at 58lbs no matter what the cross is strung at.

mctennis, when I was doing gut/zx that is about the same tension I would use in a 98 or 100" racket.

Not far from the truth for me, drive a 16 yr old car with a 25 yr old pickup in reserve. Spare bedroom is the tennis stringing, racket modding, gunsmithing, fishing gear storage & nap with the dogs on the futon room.

Or keep them in the court
So it sounds like the best use of ZX is as a slippery/soft cross? Wouldn't it offer to much power against a gut main? I'm assuming against Kevlar, it helps provide softness and a slippery surface for the Kevlar to slide on? Or a smooth, stiff poly main?
 
I've been using full ZX for a few months now. When I made the switch to Zyex from x-1 biphase, I was using My Prince Tour 16 x 18's, and I needed my ball to drop down onto the court with my full swing fh and I wasn't getting that with the full multi and balls were landing deep quite a bit. Now, I'm using full ZX in my Prince Exo Tour ESP's 16 x 16. ZX is indeed a unique string with some of the spin-related performance characteristics of smooth polys/copolys and the pop, feel, comfort, etc. of stretchier, more powerful strings like multis & syn. guts. I find it more comfortable than any copoly I've used, which is why I use it-- I'm a former copoly (Kirshbaum PL2 then MSV Focus Hex) player for years mainly for its spin production. Having said that, ZX is still a bit stiff, which I'm unfortunately noticing in my continued elbow pain.

In my 16 x 16 Exo Tour ESP I have been getting it strung at 58, which works well. Now that my elbow pain is not getting any better, I will try hybriding ZX with a softer multi--most likely Technifibre Multi feel (cheaper than x1 and still decent/comparable). What I'm worried about is early string breakage, since my 16 x 16 is so open and I am a string breaker. For that reason I may use the ZX on the mains at 58 (like before) and the Multifeel on the crosses at 54 and see what happens.

Hate to change my setup, since I've just recently started to get used to this new stick and ZX, but my arm ain't liking the full ZX. I will report back on ZX on mains with multi crosses in my Exo Tour 16 x 16. Have a feeling it will be more comfortable and still great for spin but won't last long...

Weird. No idea what will help the arm since its tough to find a softer string than zx...

Yeah i agree. Just saying though that gut/zx is a nice stringbed if you like a soft stringbed

Well, another feedback. I talked with my sister and she's been playing 3-4x a week. She's 3.5 ladies. She said the ZX/OGSM 56/55 in a Prince Textreme Warrior 100T felt weird for the first 1/2 hr. Then played great for several hours. Then it started to lose control and couldn't keep her balls in the court. She was reduced to hitting slices to keep the ball in. She even developed a bit of elbow pain (I'm assuming from using a different swing to try to compensate). So she's pretty much lost all confidence in the hybrid and even my string suggestions. So as a sign of good will, I'll re-string her racquet with full bed Xcel…this was a costly experiment. I'll have to keep my experimenting on my racquet or my son's...

ZX/OGSM is not be combined on my stringer again. I still do have a set of ZX but it'll be used as a cross against a poly...
 
Some feedback from the experienced people here.

My TGK 231.3 is strung at 67/35 with Ash Kev 17/ZX 17 black. After about weeks I noticed that mains, when moved with my finger, don't return to their original position. They behave like sun gut! Could it be that they lost too much tension?

thx for ur input. never even tried gut; pricey stuff and as of now, I'm not stringing my own, so that would be a pricey move. I did hear the zyex pairs well with gut, polys, and kevlar, but polys and kevlar are outta the question due to elbow issues.
 
Due to time constraints, I strung Kevlar/Zyex without a prestretch for the first time yesterday. For the past several months I have been playing manually prestretched Kev/Zyex at about 70/45 in a 16x19 Volkl. Yesterday I did 60/55 in a Pro Staff 6.1 25th Anniversary (which is 18x20). I was on the court about 25 minutes later and played 3 sets of doubles feeling good the whole way. It will be interesting to see how it settles my next couple of times out. I have a crank machine and took my time pulling the zyex, but am certain there will be more tension loss by the next time I pick it up.

I'm feeling similarly regarding the price of testing with gut in the mains. I think I'll test gut with Cream for a cross. I may venture to try Sgut or Multi in the main at a higher tension and ZX in the cross to help it slide. But that's going to be a pretty far down the list of stringbeds to test.

I think this time around I over pre-stretched my ZX natural. My method of setting in the pre-stretch seems to be very effective. Next time, I'll just do 3 stretches, 1 for 15 seconds at medium lean and 2 for 30 seconds at extreme lean with 20 second rests. Last time I was doing 6 stretches with rests. Then I'll let my drop weight do the rest.

The first time I didn't do any pre-stretch and just relied on the drop weight's elongation. @56/53 it felt great, but too soft. This time it feels too muted and rubbery. I think I'll have to use the right combination of pre-stretch and drop weight elongation to find the desired feel and tension maintenance. I only have half a set left and having exhausted many possibilities for ZX black, I think this will be my last trial of ZX natural as well whether I like it or not. It's a high maintenance string. And not in a good way.

When used as a cross, properly (thoroughly) pre-sretched, and paired with kevlar mains strung significantly tighter than the crosses, I can't think of a string that is lower maintenance than monogut ZX. Strung according to this recipe, it never notches, never noticeably loses any tension, never loses it's spin, comfort, or control, and lasts several months with excellent playability all the way until breakage.

And believe it or not, it's more comfortable than just about any other combo out there, since the kevlar slides so well against it. Kevlar gets a bad rap only because it locks when paired with syn gut.

I played again last night with the above set-up. It still felt nice and didn't feel like either string appreciably dropped in tension, a depth control was still there. I'm still in the evaluation stage on this. It normally takes me abut 40 minutes to string a racquet. Without pre-stretching the zyex, I get much slower (about an hour) because of the slow pulls, and obviously unless I use a stopwatch I am going to lose consistency pulling that way. That said, manually prestretching also takes time and effort (possibly more than time and effort than the slow pull method).

You're probably right about ZX being low maintenance once you have it in the racquet. It's just taking me too many trials to find a method that makes it play nice and is repeatable. With other strings, I can always figure out if it works for me within 3 stringings.

How long are you leaving the ZX string in your racquets before you restring? Are you noticing any tension loss from when you start using the racquet until you start noticing arm pain?
Just curious.

I got 4 sticks I'm rotating now and had 3 for a while. I've been using my Prince Exo Tour 16 x 16 strung at between 57 and 59 full Zx for a few hours before restringing. When the tension drops to a point where it's obviously too loose and the ball flies a bit,that's when I get a restring. My arm pain is
clssic epicondular tendonitis, or tennis elbow--super tender at the epicondyle joint and when I don't do my PT exercises, it starts to pull on both my triceps and my forearm muscles. The extensors and flexors tighten up too. Overall, though, it's not excruciating and I am able to play.

The arm soreness is a constant kind of tenderness, which doesn't seem to be affected by when I restring. The tenderness doesn't fluxuate; it's a constant issue.

AFA tension loss with Zx, what I do notice/have noticed (and read about here) is an initial rather significant drop in tension from when it's first strung up. It seems to lose like 5 lbs. right off the bat. Granted I am not prestretching. Because of this initial tension loss, I have been tensioning around 58/59, which can't help tennis elbow, I get that, but Zx is a stretchy, pretty comfortable string. 59 lbs. in a 16 x 16 pattern, though, is probably like 56/57 in a 16 x 19...

DT of 36 at this tension.

Myself and several other guys have been using Ash Kev x Zyex for a couple of years at least. Prestretching the Kevlar is amusing as it stretches maybe 1". Zyex just the opposite. However, I am pretty sure that even prestretched this stuff has pretty remarkable initial tension loss and after hitting for an hour or so even more so, then it settles in for the long haul. We all have the Kevlar strung around 62-68lbs. The young gun of our Kevlar/Zyex users swings 98" 18x20 TiRads and has his strung at 62/62. Another uses a chopped down leaded up Blade 104, another a pair of Monos and myself with 7-10 rackets strung with the stuff. None of us have had elbow issues using Ash Kev/Zyex, while two of us have had elbow issues with other rackets/strings.

I keep trying to break the Ash Kev/Zyex habit. I've tried Zyex full bed, Zyex in the mains and Kevlar crosses (not a good idea), Nat Gut mains/Zyex crosses and the reverse, as well as Nat Gut full bed, probably 10 types of poly, that many syn guts and half a dozen multis. I have accepted the prestretch ritual of manually stretching the Zyex about a foot and getting the Ash Kev another 1". The advantages using Zyex in the crosses with Ash Kev mains remain: 1) arm comfort 2) enough spin for decent rec players 3) playability & durability far beyond anything I have experienced, although Nat Gut x Zyex isn't bad either if you can find the right tensions for specific racket/player. 4) No brainer in stringing: Zyex cross normally at 59lbs because Ashaway says no more than 60lbs, depending on pattern and head size the Kevlar mains from 62-70lbs.

I think I'm seeing the light on string selections. I really, really like ZX the way I have it set up now. Once I figured out how to do it, it's not too much of a hassle. But I like my signature setup and Red Devil full bed just as much. And the Pro's Pro prices are too hard to resist. So ZX, it's not you, it's me. I'm too much of a cheapskate to continue with our relationship.

For anyone looking for a hybrid that has a premium quality multi feel, I recommend ZX natural 1.27/Velocity natural 1.30 w/ a 3.5" pre-stretch on the ZX and a 3 lbs. tighter differential on the ZX main. I use a drop weight stringer. So far after 5 days, the tension seems to have stabilized and it's supposed to last a good long time after this.

I am willing to bet the type of aramid string you are referring are coated with some sort "plastic" coating. If so, then it won't work near as well as Ashaway Kevlar. The cheapest way to get plain Ash Kev is to buy it in half sets from TW. The next cheapest way is buy a half reel. There is something ashaway sells called Crossfire ZX, but the type of Kevlar that hybrid set contains has some mix of polyfin fibers and Kevlar. This not the same or as good as IMHO as plain Ashaway Kevlar.

Not playing a lot sadly but yesterday I tried the Ash. Monog. Zyex in the crosses at 58 with Bab. tonic natty gut mains at 57 in my Prince 100 ESP 16 X 16...
In this ESP string pattern stick I tended to think the Zyex should be in the mains and the natty gut in the crosses but acting on the advice of some here (Graycait I think) that the Zyex slides easier in the crosses, I strung it up Zyex xx, Natty gut mains...

This was the first time I used nat. gut ever. I play with tons of spin both top and slices off both sides as well and I really liked it. I'm thinking I need to prestretch the Zyex to prevent the huge inital tension loss and possibly reign in the control a bit. This 16 x 16 stick with natty gut has pop/power for sure, so with big (albeit light,thin contact type ideally) controlled cuts, great feel, and wicked slice, I think I found something.... now I must deal with the cost, breakage, restringing horrors.

I would recommend prestretching a half set of zyex so that it does not permanently lengthen more than about 12". I clamp about 1" in my wood vice encased between two little pieces of folded sandpaper. Then I wrap and cross the other end around a 1.5" wooden dowel using a piece of sandpaper to hold it in place. I have a reference mark on the string with a sharpie near my end at some reference point I can measure the mark visually as well as with a tape measure later. Then I pull back on it till I get 12" permanent stretch. You can get a 20" or even longer stretch but I have had some issues breaking Zyex while stringing when it is prestretched at or near its limit.

I may get some natural gut again to try the gut/zyex hybrid in my PCG 100s.

Has anyone tried a hybrid of Monogut crosses and Tour Bite mains?
No, but my kid uses Yonex Spin G. It works well when freshly strung. Playability drops after 10-15 hrs. Drops slowly for next 5 hrs. Not competitive after about 20 hrs but will not break and is playable but no predictable control.

I haven't been using this racquet much, but it's holding tension great. I strung it on 5/4/17 and here it is 19 days later and it still feels fresh and new. I hit some serves with it today and it performed well, except that they are 16g strings in an 18x20 frame. I'm going to have to decide which way I'm going with string type. ZX is great, but I just got a reel of poly and I have about a half reel each of two other polys. And I'm a 3.0. I am able to benefit from poly/nylon hybrids, but chasing after 17g ZX would make me feel guilty. And if I love it, I would never use my poly reels and spend much more on ZX sets.

I think I've written myself out of my corner now. I've got to appreciate my ZX/Velocity hybrid while I have it in one of my racquets and not try to improve on it. I've got to start looking forward to the next combo that will go in that racquet.
 
Well, I torque the ball myself and am definite definitely a string breaker... it's all about arm friendliness and performance for me. Perhaps I'll try this Bab. Tonic 1.35 natty guy in the crosses and zyex mains for durability reasons. too bad zyex doesn't come in anything thicker than 1.27!! crud

Can anyone compare ZX natural 1.27/multi 16 to ZX 1.22/multi 17? I have 1.27/16 in my signature racquet @57/54 with a 3.5" pre-stretch on the ZX. It's holding tension very well and not notching. But I would like the strings to have more bite on the ball. Now, thinner gauges string up tighter than thicker ones, but they also lose tension faster. I've never had problems with durability, so we can ignore that. Should I tension the thinner strings the same as the thicker ones and see how they stabilize? Also, how much should I pre-stretch the thinner ZX 1.22 string compared to 3.5" out of the 1.27? After the pre-stretch, I will be installing it using a drop weight machine. That will pre-stretch it further before finding equilibrium. I found that a manual pre-stretch helps a lot with tension maintenance in addition to the stretch it gets on the stringer.

1) Same tensions for thinner gauges?
2) How much more pre-stretch (inches) for the thinner ZX string?

Much appreciated

I get your questions, Muppet, but can't speak intelligently about stringing/prestetching issues, since I've never strung sticks... sadly.

The 1.27 plays close to the 1.22 imo; it's only .5mm diff, remember. Durability, which doesn't matter to you would be the diff as well as, like you said, slightly more bite with thinner strings.

Maybe someone else can chime in RE: your main questions.

can someone compare the feel (over monogut ZX's life time), "properly prestretched" vs not pre-stretched ?

I read this thread but people only talk about "initial" tension loss.
But if ZX is that stretchy, shouldn't it lose tension continuously over the course of string's life time, if not pre-stretched ?
because it keeps elongating as you continue using it?

LOL! I have strung this stuff called Zyex so many times it is almost ridiculous. That does mean it isn't great string, but there is too much thought put into string sometimes.

Hand prestretched, machine prestretched, or not prestretched - the "masses" opine. If you want the perfect tennis string with modern strokes then get the right poly for you and cut it out every 4-10 hours. If you want to "fire and forget it" then get Ashaway Kevlar 16g x Zyex Pro 17g. If you want to impress the OCD folks then tell them some arcane story about prestretching that required some super computer designed technology. Otherwise just string up some Ashway Kevlar 16g at 62lbs and Ashaway Zyex 17g at 59lbs. Hit the crap out of it for an hour and then start playing matches in your rec league for the next 10 months.
 
I've played Kevlar/Zyex using 2 stringing methods: (1) hand/body weight prestretch where you get 12"-18" of permanent elongation and (2) stringing very slowly on a crank machine where I can feel the elongation on each pull. For the second method, I string much tighter than the first (say 58 lbs as compared to 45 lbs). I realize there are a lot of variables in play here, but I think for me those two methods turn out a more-or-less equal string job as far as feel and playability over the long run. Sorry I can't give a more definitive answer.

I was stringing full bed ZX Pro 2 days ago. Using a starting clamp I broke the knot on the top cross just pulling the first loop of the Parnell string through. I imagine it broke because of the string clamp (or bad string.) Anyway I went back to a starting knot for the top cross and it worked great.

I went with 58 lbs (lock-out) on zyex with mild pre-stretching.
I think I will go lower next time.
The main is 15L gut strung at 64 lbs(lockout).
It's unique string and I'm still trying to get used to it but it has great potential i think.

I strung up one racket with Black Widow and one with Black Widow/ Zyex.

The hybrid is still very playable and lively after 8 hours. The full bed feels dead n boardy.

Compare the degree of notching on the crosses, and the reason for the improved performance will be apparent.

Can you cut poly mains and restring with the ZX still installed?

No. Most crosses if not all are at some point tied off on the mains. So cutting the mains means the crosses have nothing to tie too and lose tension. Replacing the crosses is possible because the mains stay in place
