Inoue Kunio plays with a Yonex I wonder if anyone recognize the stick and maybe the strings on it?
Maybe the sound, power level, spin etc? I thought Yonex users could have chance to recognise..The painjob is of a Yonex Vcore Xi 98 or 100 - count the strings. If 16x20 than 98, if 16x19 than 100.
If sponsored by Yonex probably Yonex Poly Tour Pro.
Still you should think over your questions next time you post. Based on what one could identify a specific string? Color? ...
