Re: Question about Balls
I like the Roland Garros ball. It's a little tougher, and it's lighter than the other ones. I've noticed Penn in particular is HEAVY. Head ATP isn't too bad, I liked those too.
Out of those three, I'd go with the Babolat RG ball.
Serena , Venus , Petra , Ana 
Simona, Vika , Angie, Sveta, GarbiŮe
Kim , Mahree , Monica , Dokic, Sandrine, Jie
