Srixon Z Star Diamond Performance Notes
Srixon Z-Star Diamond is one of the best value tour balls of 2026 thanks to Srixon's $69 double-dozen offering. Of course, it takes more than a low price to make a great value, and Z-Star Diamond performs across the board. It ranked in the top-10 of our testing in stopping power and in the top half of all balls we tested for wedge control and accuracy, with solid scores all around. Distance proved to be Z-Star Diamond's weakest category, but it fell only one yard behind the average of our 43-ball field.
