So I usually play Callaway Chrome soft and soft x, have so for the last year. I bought two sleeves of the Srixon Z Star XV today and played a full round with those. All I can say is WOW. I was shocked how they performed. Checked up way better then the chrome soft, seemed to pop off my driver better. I was leaving chips 10 short because of how well they were checking on the greens. Will definitely be buying some more once I run out of Chrome Softs.
