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but, when we say that the pros replace poly because dead, after 45-60-90mn, there, the example is no longer valid.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