I´ve noticed this a long time ago but now I can´t take it anymore. The quality of Dunlop Fort balls has dropped astromically. I´m 15 and hit pretty hard maybe even the hardest of my club and my serves can go up to 185 km/h but theres now way that I break 4 of these balls in one match, I mean two of them even had a damn hole. Can someone explain why that extreme drop in durability happened?
