unless your source is reliable and credible, u r blowing air or someone else air. if u look at the pic below, it convincing enough that it's a real mp88 (first red version)
I can only say what I've been told .. hMmm to me it doesn't matter which racquet he is using..I just find it whacko for yonex (japan) IF it is a Slim 10 undercover
It is definitely not a MP88-like coloured Slim 10. By comparing the head shapes of the two rackets you can tell that it is an original MP88. But I'm still not sure, if sponsored top class players get rackets, which a special picks out of the whole yonex production bunch (CP/CN discussion), so they get the specs they like the most (stiff, head heavy, ...).
