in my opinion, there is no brand that is truly revolutionary.
there are endless brands that would like to become the new Luxilon, to be able to become the absolute reference in the juicy string market.
but for that ,; we should be able to make changes such as luxilon did by switching from S-gut to alu power for example, but it is practically impossible, unless you experiment with any technology other than poly!
Nowadays, each new brand, each new string becomes to read the manufacturers a little better or much better than the others, and it's been ten years that it lasts!
each in turn tries to really innovate, finally, thinks really innovates, but it is only small small, microscopic jumps.
we gain 1 hour of maintenance, or 10% of power, or of comfort, in the eyes of some it remains revolutionary, but ultimately, quite little, when we take a step back, it's never as much as going from S-gut to alu power for example! (or from alu power to full natural gut, in other criteria)
In my opinion, there are strings in all brands that are a bit (barely) really revolutionary, and that only multiplies the micro-variations of the strings.
I also tried a few tier one strings, and yes they do help, but still remain in the "close or similar to" comparison.
To date, after having tested and tried about thirty, fifty different strings, there is always something new that is a little better than, or a little worse than, or both at the same time.
but we forget what the goal of the players is.
we are not testers. the being by trying to hope to find the revolutionary miracle string that will make you play 10 or 20 levels beyond your own, it's pure madness! you will gain these 10 or 20 levels by practicing seriously, and especially by keeping the same parameters of your strings and your rackets.
Why do you think so many great players stay with the same rackets (with makeup on) for years, and the same strings for years?
in my club, there is a player who plays at 7.0 us, and who has always used olds radicals IG MP pro and signum plasma. and never change except the tension every now and then.
and I have another younger friend (28), who competes a lot, who played like me at 5.5-6.0, but who for 5 years has dropped to 4.5-5.0 because as soon as a new racket, a new string comes out, he hastens to buy them to try them out, and hopes that his game will get better! except that he never has time to get used to and progress with these new materials!
the adaptation time with a new racquet at the competition level is several weeks, with a new string, you can go up to several days, and for the right tension too. but alas, in this past time there is always a new string appearing on the market, or at least new tests of a revolutionary, magical and innovative new string! .. result: the players no longer evolve, are no longer players but testers!
