There is such a category in my experience, but BHBR does not fall into it for me. I've always liked softer stringbeds, including full beds of low-stiffness polys at ~30 lb, but even for me the two Polyfibre strings I tried like that (Poly Hightec and TCS) were uncontrollable.Are there strings that don't play well at low tension at all? I'm guessing powerful string like BHBR will feel like trampoline at 30lbs range compared to at high 40s.
The funny thing about all of this as a trend is the fact that the trend for a long time was to cut strings out as soon as they lost tension.
For the past 5-10 years the prevailing wisdom here at TW forums has been that poly loses "resiliency" or "elasticity" as it ages, and that is what creates the boardy/stiff feeling often associated with arm pain. However, there's an equal number of players who verbalize dead poly as that moment when the string bed looses so much tension, that it becomes an uncontrollable trampoline/rocket launcher.
So, let's back up the truck here, (beep .. beep ... beep...) The first thing to understand is that Poly "death" means different things to different players:
"The strings lose power."
"The strings hurt my arm."
"The strings feel stiffer."
"It hits like a board."
"The strings lose their resiliency."
"The strings lose their elasticity."
"My strings are staying out of place."
"There is no pop."
"I can't hit the ball deep."
or ...
"I can't control the ball."
"I spray the ball all over the place."
"I can't keep the ball in play"
"The ball just takes off."
"The the strings are mushy."
"The strings trampoline the ball."
"My ball isn't as heavy."
"I can't hit with as much spin."
These are all comments used to describe string death/aging, and yet some seem to directly contradict the other. One guy says the string bed becomes a powerless, boardy, arm breaker, and next says the racquet becomes a mushy, uncontrollable rocket launcher and they start spraying the ball to the back fence. So... how do we reconcile all of these various player comments attributed to string aging? Crawford Lindsey aka TW Professor has provided us some insight after extensive lab study on the issue. These (seemingly) contradictory accounts are entirely explainable.

1. Poly death is a combination of two competing factors, tension loss and increasing friction.
2. As poly ages, it does lose tension, and yes, this does increase comfort. However, it is also getting rougher and it slides and snaps back less, which reduces the dwell time. Whenever dwell time is reduced, impact shock is increased. This is most likely what creates the "boardy" feel associated with "dead poly". So these things are occurring at the same time, and eventually, one or the other will win out and dominate the feel of the string bed.
3. These two competing forces explain why there is such a wide variety of complaints about aging poly .... If it seems like it's "mushy", "trampoliney", and has "uncontrollable power", that means the tension loss is winning the battle.
4. If increasing friction is winning the battle, the sensation will be stiffness, boardy, lifeless, dead, I can't hit with spin, etc.
That is a way too short, and somewhat incomplete explanation, but you can read more about it in the links provided below. I've also posted the key quote and underlined the part that speaks to this very question for you.
[..]
Quote: " The lower tensions and perpendicular stiffness of many polyesters leads to longer dwell times and greater deflection. This keeps the ball on the racquet for a longer arc of the stroke, potentially creating "power" problems with the ball going deeper, wider and higher than desired. The decrease in perpendicular stiffness also contributes to the sensation that the strings get "mushy" or behave like a trampoline. A loss of control is the end result. Further, the stroke itself may thus be affected to compensate for the changes in the string.
On the other side of the coin, increasing static and/or sliding coefficients of friction will decrease the amount and efficiency of the sideways main string movement and snap back. This, in turn, decreases spin, lowers launch angle, and stiffens the stringbed parallel to the strings. This is perceived as a loss of power and spin as well as an increase in stiffness, harshness, and pain, especially if the player starts swinging even faster to compensate.
If only it were so easy. It seems whenever there is one causal factor acting to increase a performance variable, there is another that arises to decrease that variable. In this case, as tension and perpendicular stiffness decrease with repetitions, increasing the "power" behavior of the strings, so to do the repetitions increase the friction coefficients, making the strings feel stiffer and low-powered. And, then, in another turn, the decrease in tension should also decrease the friction between strings. So the strings are simultaneously gaining and losing in power behaviors or in stiffness and softness characteristics. It is the net effect that determines the player's perception of string performance."

It's not quotation used as an authority but as a time-saving shortcut.
Pff, whatever dude. The only person I am quoting as an authoritative source is Crawford Lindsey.
You are citing a ten+ year old book. Strings and racquets have changed significantly during that time. I am so sick of the pseudo-science yobos. You are a self anointed *** hat. Lots of posts, but nothing of real substance there. In other words, you don't know what you don't know.

It definitely seems that he knows what he is talking about within the context of this thread (and elsewhere). I would definitely call Crawford Lindsey and authoritative source when it comes to tennis science, and ChicagoJack has simply made the writings of Crawford Lindsey more concise and readable to the general tennis playing public. Now back to the thread...
Terrific information, thanks for the effort to post it. It fits in with what I have experienced in my play with poly, but scientific studies are always needed to back up anecdotal notes.1. OY. Your upset stems from something you think you saw while skimming quickly. It is an entirely self inflicted wound. If you had actually read my post, you'd see that the quotes and links I provided are not from Lindsey's book. They are from the March - April 2013 studies available in the Tennis Warehouse University. Seems clear you've never once glanced at the studies either, because the dates are listed very clearly right underneath the titles. Poly death has been mentioned a gazillion times in this thread, and I thought it might be helpful to shed some light in here.
2. I didn't quote your statement directly, because I didn't want you to feel like I was calling you out on a fairly common misconception. I'll be more direct. What you don't seem to be comprehending (perhaps because you joined TT in March 2012), is the idea that strings go dead due to lost resiliency is not the new news, it is the old baseless theory which has been circulating around here since 2008 or so, and has since been dis-proven. The March 2013 studies indicate that poly death is merely a matter of two factors, tension loss and increasing friction caused by notching and abrasion. I invite you to reconsider who "doesn't know what you don't know" here.
3. If you would like to double check my sources, my interpretation of the study, or the science behind it, I encourage you to look to the following link below. It's a tough read, but the conversation 15-18 paragraphs down, in the section entitled "The Experiment, Loss of Elasticity and Resilience Tests" is pretty illuminating and gets to the heart of the matter.

Thank you SV Specialist, much appreciated. Yeah, Lindsey is a tough read. I'm just doing my best to translate some very dense information into something more easily understood. Sometimes people interpret the length of my posts as expression of ego. I simply have a passion for certain complex topics, and these topics are difficult to cover concisely. I'm actually much more of a lurker around here. I don't post all that often, compared to many recent TT members (1,700 posts since 2005) but when I do, I try to make it something useful.

We know poly does not lose much elasticity because string that was literally hammered on until tension went to zero will behave almost identically to fresh string, provided that same string is simply re-tensioned. The testing procedure repeated this hammer till tension toss goes to zero -> restring procedure 6 times, it was designed to torture string well beyond any typical playing situations, the results were pretty amazing.
Regarding replies 2063 and 2067
We are at very strange cross roads regarding understanding the true nature of poly. We have a truck load of new information, yet the old misconceptions keep getting recycled. Back in late 90's to mid 2000's, when poly use really started to escalate, you almost never heard anybody cutting string out, and the phrases "poly death" and "loss of elasticity" were pretty rare. Now these buzz words / catch phrases are like the secret handshake to gain entrance to the club house. Yet we are sitting right on top of two very controlled studies here at the TWU that indicate strings don't lose elasticity, our most fundamental beliefs about this material are flawed, and by the way, player descriptions about how string plays as it ages varies wildly and is often contradictory.

Below are some old posts of mine that explain this a little bit.
Keep in mind that Serena (and Venus) plays full gut while just about everyone else uses full poly or poly hybrid.
Hello. Serena no longer uses an all but set up. She has been using 4g crosses for over a year. And incidentally, they catapulted her game.
I don't know. When I see her, ALL I see is but

When I see her I see a champion who has won 17 singles and 15 doubles grand slams, 3 Olympic gold medals and has the best serve in the women's game EVER. I guess it's all in the eye of the beholder.
How many hours are you getting out of this set up? I liked mid 30's full poly for about 1.5 hours and then the snap back stopped and I started having problems with control.I've been playing ELT for a while now, too, and I see no reason to go back. Found a great spin set up in BHBR x WC Silverstring. Even dragging some guys down with me as everyone I let try it seems to like it. Good stuff.

Exactly!!
Poly is awesome for a short time then it sucks!
Look we try and simulate what the pros do. The pros play a match and then use a new set of poly for the next day.......
This is the way poly was meant to be used.
I realized this and figured out a solution. ........I found a string which is almost as good as poly but it maintains tension an playability for a very very long time......it's ESPECIALLY good on low tensions.
That string is Kevlar hybrid with gut on the crosses.
Although Kevlar is not as good as poly at the outset .....it's far better after just a couple of hours . It maintains its tension and just keeps playing great for a long time.
Bottom line:
Poly > kevlar for one match
Kevlar > poly for anything after one match
Though for anyone who says 30 lbs is comfortable......it's really not.
Its relative I suppose. I thought 30 was super comfy coming from the 60s, but going down to 20, or even 15, and then going to 30, 30 was harsh at first.
Though for anyone who says 30 lbs is comfortable......it's really not.
Now 30lbs can feel harsh? this thread is hilarious, I suggest you guys just string the racket by hand. No need for a machine just pull the tension by hand, should be able to avoid those harsh 30 lbs set ups that way. lol
The only reason I ever tried the low tension was because of TE. So yeah 30lbs can be harsh to a sensitive arm.
And yes, my machine only goes as low as 15lbs. I wish it would go lower.
and it has to do too with racket size. 20lbs in and os is different than 20lbs in an 85. Oh and that 30lb setup that seemed harsh was using kevlar in the mains, which most people don't use. Kevlar produces a stiff stringbed even at 30lbs....
Ya kevlar can be pretty stiff at any tension, I know because I use kevlar mains and nothing is better for a consistent string bed.
If you have had TE and are worried about it then I would suggest not using poly and use a multi.
Yeah you are right. Though I really dig a stiff stringbed, even if my arm doesnt. Played with Kevlar for the last 15+ years I think.
I will try a multi and have in the past. I really like the Prince Premier string. Very soft and comfy.
Also, I could be wrong but since I switched to the Prostaff 85 and its more dense pattern, doesnt poly loose some of its spin magic anyhow?
I used to play gut poly at 50+ pounds.
30 lbs full bed poly is much harsher.
A steam 99S at 32 sounds a bit too audacious.
My 2 cents if it matters to anyone.
Last night I strung up a steam 99s with bhb7 at 32 to see what the buzz was about. I normally us OGSM/TCS at 54. Mostline baseline games with a big hitting partner.. ex-college 5.5 player. 90 minutes session.
As others stated the experience was not what I expected at all. First thing I noticed was the buzzing of the strings. It was very pronounced, and annoying. Second thing was the easy access to power at low swing speeds. I then noticed that the power dod not ramp linearly.. There seemed a law of diminishing returns. 75% swing speed as oppose to 90% swing speed produced almost the same ball for me depth wise. It is possible that the full out swing was producing more rpm's but I did not get that impression.
The ball DID move faster that my normal setup. There was more rpm and the trajectory actually seemed a bit lower as I adjusted. I'm normally a full western, but I felt very comfortable in semi-western and smashing the ball flatter and lower over the net. This was surprising to me.
Volleys were much nicer compared to full poly at a higher tension. IMHO this is where the lower string tension really shines. Backspin slice volleys were butter smooth, punch volleys were easy power. Drop volleys had lots of bite. They didn't float as much as I expected.
I did not serve enough to have a real opinion. I was concentrating on baseline and some volleys.
Now the bad. I felt an acute lack of control when I was not able to execute a full swing. I don't mean a fast swing, I mean the full technique. Getting jammed at the baseline where you need to grab it low and flick it up for example. These shot FLEW. I would have to re-learn these shots.
Also as I tired into the last 15 minutes I noticed my forehands getting more out of control as I throttled back the RPMs.
The worst part for me was two fold, and mostly in my head. First was the vibration. I HATED it. I did not like it at all. I can't stress this enough. I lick a crisp contact and even though I'm pretty sure the initial contact was crispish, the on going vibration was annoying as all get out. Even after 90 minutes and continually trying to ignore it it was driving me nuts.
The second was the sound. There was none besides a twang. A weird twang. An unholy twang. I'm used to positive feedback from the ball strike. This was just odd. I might be able to get used to it... might.
all and all for me it was a mixed bag. I'm not going to discount it right off the bat. I'll keep a stick strung with it in my bag and experiment with it from time to time. I'm curios to see how it servers. I'm guessing I'll get some huge serves out of it.
isn't the consensus here that extreme open patterns should be strung higher because an ESP stringbed is softer at the same tension? (less crosses stabilizing it)
I don't hit very many groundies, I come in on every serve and even most returns I'll hit and come in. I play doubles so I'd prefer a tension that doesn't have a high launch angle. A lot comments I've read deal with groundies, I'm interested in the best tension for serving and volleying. Thanks
The above might be what I'm experiencing. I should try it at 38 to 42 and see what that is like.
