Comments: The string broke while I was pulling the last knot (by hand). What was left was too short to tie the
knot. A waste of $15.

Comments: Not a fan. I had this strung 10% higher than my usual full poly set up and it just doesn't work for
me. I find it over powered and tinny feeling. Nothing like gut. I had a few other guys play with my racquet and compare it to
the same stick with Tour Bite. Everyone disliked the ZX feel and lack of spin.
From: Paul, 6/15 Comments: I think there must be some sort of formula switch with this string. I bought/used and liked this string I bought about a year ago. I bought a new pack and it plays nothing like the so called same string as the one I just purchased. Same racquet combination, same tension but plays and feels no where close to the older one. I cut out these strings I did as a hybrid with gut. That was a mistake. Too stiff and plastic feeling. I was afraid I would get tennis elbow or should problems with this string after reading the review two below mine (from David). Sorry I have to give this a thumbs down vote. If this is a new formula, please bring out the old formula version.

Comments: I played with this string in a two different racquets and the first one was a BLX Pro Staff 95 as
with XCel 17 and it was ok. Then I tried it in a Pro Staff 95S as a main and it felt horrible. It feels too plastic and stiff and
sensitive elbow didn't like the strings at all. I did cut it out the next day. I can't see where it feels like a gut -- it's not even
don't recommend buying this string.

Comments: I played with this string for a month, strung it twice at 55 lbs mains and 50 lbs crosses on a
string pattern with a 62 RA. It gave me good spin, but it felt kinda stiff. I thought it was stiff because of of advanced

From: Fred, 4/14
Comments: I bought two sets of strings based on their amazing physical metrics. On paper, in terms of
properties (stiffness, etc.) they seemed to be the closest thing to gut. However, in the real world, they felt horrible. The
told me those were some of the stiffest strings he had ever strung. After playing for 30 minutes, I decided to cut my losses
and cut them and return to my standard Technifibre X-Biphase 16 gauge. If you like any of such "soft" playing strings that
gut like, you will most probably hate this ZX strings. It plays completely differently. It feels stiffer. It has a disturbing high
metallic sound. When I played during the same practice session with my Technifibre X-Biphase, the contrast was brutal.
was no doubt, I had to replace the ZX with the X-Biphase immediately. I am really puzzled on how a string can look so
objective physical metrics (low stiffness like gut). But, actually feel, play, and sound just the opposite is beyond me. My
that the physical metrics capture one thing. And, they miss out a lot. In other words, don't just buy strings based on
metrics as I have. The latter provides you either flawed or incomplete information.
From: Guy, 11/13
Comments: Too much vibration with these strings. Need to be used with higher tensions (close to 60 lbs),
aren't designed to be strung at the high tensions (difficult to string it at 58 lbs and higher). Durable, holds tension well,
balance for all types of strokes. It isn't very efficient in terms of developing of spin. I cannot recommend these.
From: Bedrock, 10/13
Comments: Fantastic string! This is the second feedback after April, 2013. Now I hybrid ZX on the
crosses with a
soft co-poly on the main. My favorites are 17ga YTex Pro-Tour and 17g Topspin Cyber Blue. These hybrids are phenomenal
their performance characteristics such as feel, comfort, power, control, durability, etc. Tension retention seems to be quite
when properly handled. ZX is a highly elastic string. It stretches while being pulled, you are gonna have to pull three times
more making sure stretching has stopped. Therefore, stringing will be more time consuming than other type, but it's
Now I have four of my customers on MonoGut ZX.

Comments: This string plays amazing as a cross string. I was playing with some unknown super soft
it killed all the feel and touch from my K90 racquets, something I thought no string could do, so I cut that out in three days.
I tried this string and it feels better than LaserFibre string (if anyone remembers the brand), it seems that the string is best
hybrid and not a full bed, tension maintenace so far seems great, but I've only hit three hours with it.
From: John, 6/13
Comments: I strung this at 55/53 lbs in a modified Pure Storm GT using an electronic CP machine
Ashaway's detailed instructions to avoid breakage during installation. It's a very comfortable string with a feel similar to a
co-poly or stiff multi. However, it's also very powerful and offers very little control or feel. After a month of testing I came to
conclusion that other strings offer far more control and more spin with the same power for the same or lower price. The
simply too erratic in performance compared to strings in the same price range.
From: Tim, 6/13
Comments: Fantastic string. It has it all. Power, ball pocketing, arm friendliness, durability, to name a few.
it's wrong to compare this with a poly. The elongation is like a soft multi, yet the durability is close to a poly. I first tried
ZX full bed on my Microgel Radical OS and it feels weird. Then I used it on the mains with Isospeed Control Classic 16 on
crosses. Now it's a million dollar hybrid. There is one caveat though! You have to double or triple pull since the string keeps
relaxing during stringing. Ashaway acknowledges it. I would recommend every serious tennis player should try it out. I am a
4.0 doubles player and a USRSA certified stringer.

Comments: I like this string. It is soft on the arm, powerful, good spin, does not need straightening, and
tension. Plays a bit like a poly but also very soft and powerful.

Comments: I absolutely love this string. It gives me great pop on flat serves. My kick serve kicks and my
groundstrokes have great topspin and my slice bites. I just recently had rotator cuff surgery and played with a poly string.
string is a little much as a full bed and can definitely feel a bit harsh. However, if you put this string in the mains with a soft
gut or multi in the cross, it plays amazingly well. I strung mine in a Prince EXO3 Rebel 98 at 54 pounds in the mains and 57
pounds in the crosses with Ytex YTouch (similar to Wilson Sensation).
From: Dan, 12/12
Comments: I like this string a lot but why do the crosses move in both directions (up and down). The
move. I've been stringing for 30 years while never experiencing this phenomenon with any other string. I can't find an

Comments: To me, this string played like any soft poly. Very, very similar to a Polyfibre or MSV string. I

To mention the word "gut" in the description of this string, should be criminal.
