String tension for copoly: What do you use?

[Joshchan]

To the original question, I've tried dozens of combinations and prefer most polys at 47/45. This seems to be the natural elongation of this string material. Any looser and it feels like a plastic flyswatter. Any tighter and it feels like a board.

A few other notables:
-I find poly never works in a head size <95 (too stiff).
-It never works in an 18x20 frame (too stiff).
-It only works in 18 gauge (<1.20mm), otherwise it's too stiff. The thin gauge isn't a problem because poly rarely breaks, it just dies and then feels like a flyswatter.
-I get around 2 weeks of play (3 sessions/week) before the poly dies.
-I use RacquetTune as well, and find the string is dead when it has lost 15-20% of its original tension. Don't forget to measure the string factor of every new string size/type so that RacquetTune can accurately measure the tension.

RacquetTune works like a charm.

It works very well in tracking tension loss. It might be a bit off measuring the exact tension. A day after having my rackets strung at 24 kilos, the app gave 19.7 kilos (The strings will lose tension the first day even without playing with them).. After a couple of days, I played with it and the normal tension loss after stringing + the loss after one hour's play resulted in 17.3 kilos.

Right, but for those who play with copoly strings and don't restring often, what tension are you playing with once the strings have settled? Anybody using RacquetTune to keep track?

Interesting. A sophisticated device yet with a very crude way of inputting the information. Does it work?

Try Solinco. The strings seem to hold their tension a bit longer than the average poly and I know many high level players that have made the switch from babolat rpm and luxilon to solinco. Their tour bite string is very popular.

In my experience poly strings don't so much lose tension but start to develop a wiry feel. All the poly strings I have tried tend to be quite similar in the way they play. I guess this is because strictly speaking they are a single monofilament. Isospeed Black Fire does tend to have more elasticity than most I have tried, but then it is a co-poly string so has other other materials somehow added to the mix.

Back in the days of nylons strings, strings had finer, nylon outer wraps wrapped around a monofilament centre core which was used to alter the playability. Some had one wrap, some had two wraps. The angle of the wraps also played a part...as well as many other factors. I discovered all this years ago when I ran a small business (for ten years) importing tennis strings and stringing machines. I ran this business together with my wife.

Kyle, thanks, but I prefer hearing from players I know. Reading articles is OK, but I prefer actual experience to theories, which is why I posed the question among the players here. Of course there is quite a drop in tension during the first couple of hours of play and then after acouple of weeks, it remains more or less stable. Since I am not a Roger Federer who can afford to use about 7 rackets per match, but restring just a couple of times a year, I was just interested. For players like me, the initial string tension is less interesting then the more or less constant tension achieved after a while. That is the one I will be playing most with.

Am using the app RaquetTune to track the change of tension as time goes by.

Then I read that Volandri uses about 19 lbs for clay!

Apparently Beppe Merlo used natural gut strung a 30lbs. His stringbed must have been like a trampoline.

Natural gut always the way to go when you got money to burn or getting it for free. It offers the best in comfort, control, spin, power. Doesn't last long. Babolat VS Gut is the Rolls Royce of string in my opinion.

Back to poly, certain manufacturers prefer you string it a bit looser than a normal syn gut or natural gut job. There are many variables to consider when considering string. Style of play, heavy spin, indoors or outdoors, type of racquet used etc etc.

Phil, although I'm an certified MRT for USRSA I have no issues leaving up to the real gear heads. You may want to reach out to Matt Previdi who has some articles on the site. He may be able to give you a specific idea of what you may need.

I remember getting a new Jack Kramer Pro Staff frame (wooden), new VS gut that was sprayed with gut spray (the smell). Along with a can of new balls at a dollar fifty a can. Total cost maybe 46 dollars. It felt like Christmas...especially those new balls. To hear that seal let the air in and then the aroma of those new balls. It smelled like victory.

I know you pay more for balls and rackets in Europe, but that $1.50 in 1976 would be $6.36 in today's dollars according to the Bureau of Labor Statistics. We only pay about $3 per can of 3 or less than half of what we paid in 1976. And that $46 would be about $195 in 2016 dollars. And the $1.25 an hour I worked for making tacos until 2 in the morning so I could play junior tournaments in the daytime the summer I graduated from high school would be $9.31/hour today, more than they are actually paying people to work in the same jobs today. We paid about $16 to $20 for a good gut string job in the late 60's and that would be about what it costs today and maybe even a little more than what we would pay today. But we made the string jobs last and even repaired broken strings. I don't know how the kids can afford to play when they go through a racket almost every hour they are on my court. It seems like they need two or three string jobs a week. I would never have been able to afford to play, even stringing my own rackets.

But there definitely was something special about a new frame with a fresh string job. When was the last time you saw a player jumping on his strings between points, ala Nastase, trying to loosen them up just a little bit?

Progress...and life

The sharpness of freshly stung gut in a wooden racket brought things to life. Do you remember that kind of "slippy zing" sound as the ball ran across the strings. And, yes, new balls to boot...heaven.

A new gut string job in a new wooden racquet. Think about the components. Wood (live from the forest), the gut (sheep intestines)...life woven into the fabric of the game. That racquet felt like it was alive. Translated into the ball being moved around the court between two players going forwards and backwards as well as side to side. It was a different game...completely. It has been reengineered...beyond recognition. Oh well...that's "progress".

Having used the Jack Kramer Pro Staff myself I can tell you my experience was identical. The sharpness of freshly stung gut in a wooden racket brought things to life. Do you remember that kind of "slippy zing" sound as the ball ran across the strings. And, yes, new balls to boot...heaven.
