Actually, who plays what golf ball on Tour is less important than which golf ball you should play to get the most out of your golf game.
It is very relevant that Srixon golf balls have a lot of winners. But take some time to select your golf ball for what you consider a win.
Better, straighter tee shots? Approach shots with more stopping power? Greenside control, with more spin on shorter shots? A
responsive feel? Srixon Z-Star golf balls have it all, but what is the win you want?
