Having said all that, I do agree that the grunting/shreaking is out of control. Stan Smith said it best a few years back, he called it legalized cheating.
If you can´t hear the ball coming off your opponent´s racket because they´re having a mini-orgasm, you can´t tell what kind of shot is coming or exactly how fast it will arrive.
And that´s bull.shit, but I see no way to fix it now that it´s become so commonplace to FREAK OUT OMGIMHITTINTHISBALLSOHARD whenever you hit a dropshot.
