This settles it. Commentator of the match between Wawrinka vs Donskoy in St. Petersberg open today stated that he was told by most of the well known manufaturers of Polyester strings told him that max lifetime of poly string is 45 minutes. That is big part of the reason why ATP tour pros change rackets during the match. I say Part of the reason, because another big reason is Tension loss as well. So yea, all those sensitive guys out there thinking why does my poly string feel dead after only 4-5 hours of play,, You are not imagining it. It really is going dead. So if you can afford it, string polys often.

This does not apply to the common tennis club player. There is a huge difference between what a pro needs in order to maximize his performance and what a tennis lover needs for playing his favorite sport. I understand that the concept of the capitalism is to consume more and more, but hey, we can still play with the same strings for some days.

Right, i think for amateur players that don't hit as hard, poly usually last about 4-5 hours, some little more. I think luxilon alu power last up to 6 hours. i am 4.5 level player just from comparison purposes.

There's a guy I practice with whose consistency varies - he hits hard but some days his shots are beastly and other days the back fence gets a beating. He figured it was fatigue or technique but then he used a tension tester on his rackets and was shocked to see the tension drop between used and new strings. He used the same racket until the strings broke, but was much happier after preemptively switching to a freshly strung racket.

Don't know about loss of playability from other factors (loss of coating, elasticity, etc), but at least tension loss should be easy to track.

Presumably apart from pre stretching pros don’t bother to compensate for initial tension loss either; this would be a contributing factor to a minimised optimal performance window.

I think for any decent player (3.5 and up) 1-2 hours is about all you can expect to get out of a set of any poly or multi. Some claim gut keeps its tension until it breaks but I don’t know if that’s true. I just know that almost every time I use a freshly strung racquet the result in play is noticeable and I’m not even that good. But for us club players cost means we must play for several hours beyond ideal.

Gut basically does keep its tension and playabilty during the entire time it is in your racquet until it breaks. It may lose some tension but not enough to really notice enough to make a huge difference like polys or multis do.

Someday I’ll give gut a try but the cost and durability concerns always have kept me away. What I’ve basically settled into now is a realization that the crisp feeling I love on a new string job isn’t a requirement. I can play about 10 hours with the strings I have now before the tension loss become unplayable. But if I could afford to I’d probably restring my racquets after like 4-5 sets. And I guess if I didn’t have to pay I’d use a new racquet every set or two.

Try some gut or a hybrid get set up and see what you think. I have been using a hybrid get set up for 25+ years. I like the way gut lasts me longer than a non gut setup.

I tried a hybrid once of multi and poly. I felt like it was the worst of both worlds. Full poly is awesome but it gave me TE in less than a month. So for now I stick with multi but maybe I’ll give gut another go sometime.

I really enjoy gut/poly hybrids. I prefer it to full gut for many reasons including added spin, non-locked stringed, it is almost 1/2 the price of full gut. To me it makes complete sense and others have said I get 4-6 months or so out of a restring. This spring/summer I have played almost every day. That is a lot of tennis. The only downside is last Spring I was playing when the sky opened up and it started to pour down rain. I tried to shove my racquet in my bag and sprint for the car but my bag was soaked too. "Gut and water" don't mix... or maybe they do and that is the problem.

That’s the other thing. Here in New England it can rain almost anytime and the humidity is quite high in the summer. I’m convinced that if I buy gut I’ll just be wasting my money because I’ll leave it in the car. Or the ball will hit a puddle and my strings will get wet or whatever.

We get pretty humid here in the middle part of the west. Really, I have not had issues with humidity negatively impacting the gut. I do not leave my racquets in the car.

I think the expense of gut/poly can be comparable to full poly if you string for yourself (Even more so if you pay someone to string your racquets).

Right now I am playing VS gut/cream. So that is $21+$3 or $24 a string job. Let's say I restring 3-4 times a year that is $72-$96.

I also like a full bed of Volkl Cyclone Tour which is poly. Let's say I get about 16 hours of hitting before it is a rocket launcher. Or, for sake of argument 8 hits over a month. VCT is $7.65 pulling from a reel so 12*$7.65 = $91.76.

I am not saying this is the case for everyone depending how hard they are on string but at least the expense can be comparable between gut/poly and full poly.

I’d say you have found an excellent value in string. I have settled on Prince Premier Control. I find it provides almost all of the spin poly provides without sacrificing comfort. I can get about 5-10 hours out of a string job on that depending on how hard me or my opponent is hitting.

My buddies who don't want to spend on a gut hybrid have me string them up with PPC in the mains with Silverstring or Tourna Big Hitter Silver and they really like it. I agree 100% it holds tension really well and provides nice spin. They usually toss me a $20 or so and the setup costs me $6-$8 in string. A few others like Velocity which is similar.

I really love Gut/poly hybrid as well but then when Poly goes dead, i can definitely feel suboptimal playability coming off the string bed. Gut will try its best to keep it going but 1/2 of your partner in the bed is dead, you can only do so much.

I like Alu power soft in the mains and natural gut in the crosses. All at 52 lbs. Seems to last about a week or two.
 
yes string condition does have some effect on game play but an even bigger effect is ball condition
unless ur using a new can of balls every 30 minutes saying changes in ur strings effecting ur game is just blue pilling
even playing with balls a day old vs new one is so different it can be considered a completely different sport
now look at what people play with at the park maybe 4 balls all with different pressures different fuzz amount etc and they come home complaining how string tension loss is the reason why they missed a sitter

Yes, I have to admit the poly does die. However, I am not sure if because the poly is in the cross and I don't notice it or if as the poly gets deader the gut gets livelier but I am able to play with the setup long after the poly has died. When I actually choose to cut out the string is when the gut stops performing for me.

Maybe because I am playing at relatively low tension and also with cream which is softer I don't notice the dead cross string but I can certainly see with other stiffer poly in the cross that when it dies one would want to restring.

PPC 16 has become my go-to for any locals who need a multi re-string (I string at home). I've tried it in one of my own racquets and I think Prince has really nailed it with this string in terms of adding that tiny 3-filament core to help it retain some tension. I might eventually get myself a reel of the 17 ga. just to scratch that curiosity itch - I often like the crisp and punchy feel I get with a thinner gauge, at least with syn. guts.

The syn. gut that has been my favorite in recent history has been Kirschbaum and a few of our pals here have been really liking that string, too. More buttery than most syn. guts without turning to mush like some multis can do after a couple of hitting sessions. Supplies of this syn. gut in the US ran dry a year or so ago, but the company claims to have new stock on the way now and it might show up again next month. If you want a combo of crisp and cozy in your own racquets, this syn. gut could be ideal. Bonus points - when it was available here it was selling for about $35 for a full reel.

I've also found very good results over the last couple of months stringing my Volkl C10's with Gosen OGSM 17 tensioned down at 53 or 54 lbs. I've never much cared for this syn. gut in a full bed because it was always too harsh and tinny feeling for me. But now that I got enough of a clue to drop tension with it, I'm finding better-than-expected feel and performance. OGSM also seems to have a significant edge on other syn. guts in terms of durability, too. If I take another chance on the 16 ga. option, I might try it at 50 or even 48 lbs.

Do you break it.

I get 30 hours on the 16g. before they break. One or twice I cut them out because of movement.
Have one stick with Klip/PPC. At 20 hours the Klip looked beat up. Still looks beat up at 50 hours.

Have just used up my reel of PPC, (feels like years), will be trying 18g multi.
Have to say PPC is the only multi I get 30 hours. Do like the feel of Klip, get more power, and spin.
Both strings are a soft ride

Really like Kirschbaum syngut. In fact I still have at least half a reel Somewhere. I also liked their touch multi. It’s just expensive.

I rarely break strings. I typically find the drop in tension makes the strings unplayable before than. Usually around 10 hours with PPC. With a syngut I might get half that?

It’s a great time to play tennis. The string choices are so much greater and better than they were even 10 years ago.

this whole "poly goes dead after X hours" is just a myth already debunked by TWU Professor, why does it come up all the time still?
I get about 20 hours out of a Hyper G set before it breaks and it plays very consistently over its lifetime. In a 18x20 racquet it would probably last ever longer.
I don’t think there’s much doubt that poly loses tension and elasticity much quicker than multi or gut. You have to remember that it was originally marketed as a remedy for chronic string breakers The idea was that it didn’t fray due to monofilament construction and the fact that strings slid nicely over each other.

But in time the competitive aspects became immediately noticeable. Most players use poly because of the amazing spin and control it gives them. But that control and spin clearly comes from the snap back effect. And that effect diminishes pretty rapidly according to all the tests and what the engineers know.

So just because you play with your poly long after it’s gone dead until it breaks doesn’t mean anything about these facts.

That is not what I have seen with 16L Hyper G. In a blade 16x19 after a set and a half and it becomes a rocket launcher. The tension is gone and so are the sharp edges. One only needs to check the tension at this point.

Poly is so overrated at the club level.
Bingo. If you don’t play at least 4.5 level (or maybe even higher) you are getting nothing from poly strings. Zero. The next 4.0 that I see hitting with enough spin to benefit from poly will be the first. For everyone else, a full bed of natural gut or multi will give you plenty of spin and be very comfortable, even in very stiff frames.

So your level of tennis is near a pro's? It is highly improbable that after 90 minutes of hitting, your tension is reduced dramatically and the sharp edges are gone. Pros using full poly, like kyrgios and tsitsipas, can play around an hour with the same racket. The reason they change rackets is not that they are unplayable but they do not have anymore the feel they are used to.

Heck no I am old and stink at tennis. My son though is pretty good and yes in 90 minutes it absolutely goes away and he hears that from his peers as well. You can see it on the ball, the players ability to control the shots, etc.

Again, all one needs to do is take readings after coming off the stringer and then after play. You don't need to take my word for it you can see for yourself.

there are unanswered questions ... forever.

why do we say not to use poly in a light racket?

why do we say not to use poly before a certain age?

why did we invent poly soft?

In my opinion, to say that poly keeps all its dynamic, flexible and elastic capacities throughout its life is a lie.

if not, why do the pros, many pros, if not all, replace their poly after 45mn to 1 hour or even 2h? just because they want to? I do not think so.

I think people take it as an argument that the pros use and can use poly, so anyone can, since it's the best.

but, when we say that the pros replace poly because dead, after 45-60-90mn, there, the example is no longer valid.

today, poly is the simplest string to make. and the cheapest.
technologically speaking, when you compare poly to s-gut, it is much more complicated to make s-gut.

and multi is all the more complicated to build than s-gut.
the question is: why do everything so that people use and buy poly?

in my opinion, it is the physiotherapist lobby that is below. no, just kidding, but I think it's the material that allows the most financial profitability.

and telling people that they are buying something expensive, but that it will not last beyond 6 hours, is also to criticize the product you are selling. therefore, unacceptable.

for example, a string brand, writes this: (tecnifibre)

ATTENTION TO IDEAS RECEIVED ON POLYESTER!
People tend to believe that if polyesters are played by Tour players, it means they perform better. However, their issues are very specific and different from ours! Indeed, professionals very often play with very heavy rackets and are physically very sharp. They also change racquets every seven games on average. Their needs are therefore totally different.
As for believing that polyesters perform better or that they offer more effect is a mistake: all scientific studies show that this is a misconception.


he is a seller, a manufacturer. why in this case criticize its own products? because it's the truth!..

if a poly was that perfect, and the loss of tension, and playability didn't exist.

why don't we all play with some amazing string, made of soft poly, textured in the shape of a triangle or square, with a gauge of 1.40 or 1.50mm (like the s-gut jersey savarez).

that would be wonderful. no one would break anymore, and the string would last 2 months, maybe 6 months, or even a whole year ...? no?

and if the strings don't lose their capacity, why do pro players replace their rackets so much, when the string isn't broken?

20 years ago, we saw and heard the players breaking their strings in the middle of a game. it is increasingly rare. because they replace them long before. because..? I don't know ... for fun?

Poly is cheaper. People will not pay 20 EUR for a multi, when they can pay 8 for a poly that will last longer. Last longer aka not break. "Last" is a subjective thing with poly.
Do I need poly? No. Will I play better with poly than with any other string? Also no. Do I like poly? Yes. Will I use poly because it's cheaper to replace it every month than to replace multi every 2 weeks? Also yes.

in fact, in theory yes, this logic could be valid.

except that "low cost" poly have a very bad reputation.
it suffices to see that with each new poly costing less than 3 €, it is always compared to alu power, which is anything but economical.

and such or such poly lox cost is worse than aluminum, plays less well than aluminum, and all that! ..

my best budget option is: tonic babolat / pure aramid PP

it costs me around 12 + 4 €, so around 16 €. and the service life is much higher (voltage stability) at any poly. well beyond 3 pm-8pm! and in terms of comfort, it's much better than a lot of multi!

but now, no pro plays with that! and since natural gut is expensive string to make, and generates little profit for sellers, there is no point in promoting it !.

When people say poly goes dead after xx hour, does it mean xx hour of hitting or xx hour after stringing even if it is not used?
That was my point. It goes dead even if you let it sit in a frame for a year. Faster if you play. Usually its both combined. Playing stretches it more so it loses its elasticity faster.
You can buy new car tyres, let them sit for 5 years and they’ll be undriveable.

I just know that almost every time I use a freshly strung racquet the result in play is noticeable and I’m not even that good. But for us club players cost means we must play for several hours beyond ideal.
I won't speak for other players, but as a decent 3.5 with reasonably good technique, multi barely lasts an hour before it pops. I've never really liked multis though, I even prefer cheapo syngut, though that also lasts about an hour.

I don't see any advantage for a club player to use poly over 50 lbs. It's stiff as a board, is super low powered, and for us hacks doesn't produce that much more spin than a decent syngut. Maybe for the 4.5s and up, but for me and my league? I just don't see it. I wouldn't play with it in the first place anyway, and when it goes soft and starts being a bit more comfortable, it's still low-powered and produces even less spin than before.

Now about that low-tension poly, I just love that stuff. Tons of spin, big sweet spot, pretty comfortable, and it plays well for a long time.

Someday I’ll give gut a try but the cost and durability concerns always have kept me away. What I’ve basically settled into now is a realization that the crisp feeling I love on a new string job isn’t a requirement. I can play about 10 hours with the strings I have now before the tension loss become unplayable. But if I could afford to I’d probably restring my racquets after like 4-5 sets. And I guess if I didn’t have to pay I’d use a new racquet every set or two.
I also can't justify using gut. Even if I string it myself, it's just too expensive to play for what, an hour before it snaps?

When people say poly goes dead after xx hour, does it mean xx hour of hitting or xx hour after stringing even if it is not used?
Any string will lose tension without being played, but a even a 30-minute hitting session is going to drop the tension more than leaving the racquet out for a few days. I'd say a 1-hour hit may be about equal to a few weeks of tension loss. Play will also wear on the strings, so even if they two racquets have similar tensions - one played and one unplayed - they might not play the same. If you string your racquet with poly, as long as you don't keep it for a really long time, like a year before playing with it, I don't think you'll be "ruining the string".

Maybe you hit harder than me. When you say pop do you mean break? I used to play with Gamma Livewire and I had to string it a couple pounds tighter than I wanted because what would happen is that it would make a pop after about 15 minutes play and it would be at the tension I wanted. I would then get about 45-90 minutes of absolute dream play before it popped again and everything would sail.

I agree that all these amateurs on here talking about string their racquets with poly at like 58lbs leaves me shaking my head. When I tried poly I went with 45lbs in a Prince 100P. It was great. Such control. I felt like I could do whatever I wanted with the ball. But after a few weeks of playing with it felt the twinge in my arm and cut it out.

This is the only time I ever got TE from tennis. (First time was from racquetball) so I won’t go back to poly. A good multi works fine for me. But syngut can just go in the trash as far as I’m concerned. Might as well String with rubber bands.

This settles it. Commentator of the match between Wawrinka vs Donskoy in St. Petersberg open today stated that he was told by most of the well known manufaturers of Polyester strings told him that max lifetime of poly string is 45 minutes. That is big part of the reason why ATP tour pros change rackets during the match. I say Part of the reason, because another big reason is Tension loss as well. So yea, all those sensitive guys out there thinking why does my poly string feel dead after only 4-5 hours of play,, You are not imagining it. It really is going dead. So if you can afford it, string polys often.
This does not apply to the common tennis club player. There is a huge difference between what a pro needs in order to maximize his performance and what a tennis lover needs for playing his favorite sport. I understand that the concept of the capitalism is to consume more and more, but hey, we can still play with the same strings for some days.
there is other options though. I found Kirschbaum Max Power to hold up pretty well in both durability and playability.
All of this plus the tons of personal testing I've done has led me to pre-stretched polys. There are so many factors that affect how long the poly lasts for rec players and for me it's about 6-10 hours. But if I get a quality pre-stretched poly, I've found that it can last much longer without as big of a drop in playability or comfort. That's why I'm sticking with Kirschbaum and Grapplesnake. I wish I could use Luxilon or even Solinco strings but I can't afford to re-string as often or suffer through the drop in play.

IMO Kirschbaum is just a fantastic string company. I don’t see the attraction to Luxilon myself.

Maybe you hit harder than me. When you say pop do you mean break? I used to play with Gamma Livewire and I had to string it a couple pounds tighter than I wanted because what would happen is that it would make a pop after about 15 minutes play and it would be at the tension I wanted. I would then get about 45-90 minutes of absolute dream play before it popped again and everything would sail.

Yes, by pop I meant breaking. That's a strange story about Gamme Livewire, but I don't have much experience with multis. The ones I've tried did not work out for me at all, and they all broke way too fast for me to even consider tweaking setups to my liking.

It's too bad about the TE, have you tried hybrid with a multi in the crosses? (I wouldn't recommend multis or synguts as mains because they break really fast, the poly saws through them) I'm not a huge fan of hybrids, as I always feel like getting a decent setup takes a lot of trial and error, and until then the playability doesn't last very long, but it may be worth the effort in the long term.

That was my point. It goes dead even if you let it sit in a frame for a year. Faster if you play. Usually its both combined. Playing stretches it more so it loses its elasticity faster.
You can buy new car tyres, let them sit for 5 years and they’ll be undriveable.
but you dont change tires after 2 hours, do you?
Btw do you know why the rubber of tires hardens? Its because the uv component of sunlight which is bad for your skin too, creates radicals which forms extra crosslinks into the rubber which makes it more stiffer. Maybe something like this happens too when playing tennis in sun light. In soft plastics like soft poly or nylon too, extra ingredients weakeners are added. They could probably escape with time from the material i can imagine. In gut is mineral oil that can leak so i think also natural gut is not that durable. I remember it frays because its soft and in humid conditions it breaks before you are warmed up. Think about that poor girl in the semi final of Roland Garros. She even ran out of racquets.

this whole "poly goes dead after X hours" is just a myth already debunked by TWU Professor, why does it come up all the time still?
I get about 20 hours out of a Hyper G set before it breaks and it plays very consistently over its lifetime. In a 18x20 racquet it would probably last ever longer.
seems the article says that there is tension loss over time...
my takeaway from the article, and my experience, is the time to "dead" is dependent on your definition of dead.
a pro, who has finely tuned sensitivety might have a shot grouping (to use shooting terms) of say a 2ft diameter, whereas a rec hack like me might have a 5-7ft shot grouping... so i might not tell if strings are dead for a long time (ie. can't distinguish a bad shot as due to strings vs. my own poor ability)

if you're a pro race driver, that needs ultra sticky tires where bad tires will cost you seconds in cornering..... will be changing tires on a frequency measured in hours...
i think the better you are at tennis, you become more sensitive to what is "dead"
i personally can't tell, and by the time i get a feeling it's dead ("is it really dead, or am i making excuses because i suck?"), usually it breaks (8-10h of hitting) :p
