Thanks for the great work you share with us, especially the Wawrinka grunt. Sounds perfect.
I was watching Wawrinka's match a bit ago and it occurred to me that many of his grunts come about 2 tenths of a second after he strikes the ball. What I did was take a couple of the Wawrinka grunts of yours and inserted .2 seconds of silence and then faded in the grunt. So now his grunts vary from exactly when I hit the ball to briefly after contact. Sounds absolutely perfect on my game and very realistic. There are a lot of players that grunt after contact and this method is an easy way to make that happen in TE.
