“Koepka is one of many Srixon staffers to use the Z-Star Diamond , which possesses a softer feel and more spin, especially around the greens, than the standard Z-Star.”

“Koepka opts for Srixon’s Z-STAR Diamond, which, when compared to other balls in the Z-STAR line , doesn’t rank as the longest or highest-spinning option off the tee.”

“Moving to the golf ball, with the model Spaun uses the Srixon Z-Star Diamond, which is one of the best Srixon golf balls on the market.”
