Maybe I did not read a past thread but I just got the Pro Hurricane Tour that he supposedly uses. There is no way the string in his racquet is Pro Hurricane Tour. The colors are not the same, unless and completely possible babolat make him his own color. I think it is a poly string call Smash spiky or smash honey. Here is my reasoning: 1. we all now he uses a 15g string. Pro Hurricane does not come in this gauge, but kirschabaum maker of the smash spiky string does. 2. colors are different.
