What kind of tennis balls do you guys use? I use the Dunlop "Grand Prix: Hard Court" I heard that it was used in the Australia Open or Wimbledon until a year or two ago. Dunno if thats true though... But I was wondering what kind of balls you think are the best. As in long lasting, and in quality wise. IMO gamma balls suck, absolutely HATE them. But value your opinion if you think otherwise... just wont think too highly of you!:mrgreen: haha, but lemme know!
