Vassallo as far as I know has the stock version (customized for sure), Vliegen uses a pj of the old Major X-One Guy Forget and for Rochus I don't know up to know.
But I can tell you that the T-Fight 325 will not be continued next year. TF will have a new players racket series. Until now I only know the specs: There will be a T-Fight 320 und 335, low profile, 97 sq in. I think they will be the same mold, both rackets will be available wit 16 or 18 main strings.
The T-Fight 315 will not be continued, too. It will be modified to the T-Feel 305 with a 18x20 string pattern. (T-Fight 315 and T-Feel 305 are already the same rackets at this time, only weight and balance are different and the string pattern. So they just take of 10 gr. weight and change the name.)
Edit: Just recognized that Vassallo also uses the 16x19 version.
This is extremely interesting information. Thank you for bringing this to my attention. Do you have inside sources from Technifibre or something? I hadn't heard of any of this before.
