I'have notice on TV Fed has no more this representative BBAlu's silver-grey (X) and Nat Gut's colors (M) on his string pattern during the AO. It's now all the same mat white everywhere. I guess it is probably some new NXT from Wilson string industry that would have seduced him... Or a Wavepower mono in the whole pattern. BTW I found his strokes less bouncy and loud than before but a bit more speedy... but I admit this is a subjective interpretation. What do you think?
