Testing Approach

In testing and evaluation conducted by GolfBallTest.org, the Srixon Z-STAR and Z-STAR XV were subjected to bench testing for compression and cover hardness, and to player and robot testing using the driver, 6-iron and sand wedge.

Notable Observations

Player testing was conducted across a range of ball speeds on the Z-STAR and Z-STAR XV golf balls. Overall, the Z-STAR XV exhibits slightly more spin off all clubs (driver, 6-iron, and 56 degree wedge) than the Z-STAR at the highest ball speed level we tested while at middle and lower ball speeds the Z-STAR exhibits slightly higher spin than the Z-STAR XV. Both the Z-STAR and Z-STAR XV have mid range launch angle characteristics.

Driver Testing:

The spin rate of the Z-STAR was approximately 150-250 RPM’s higher than the Bridgestone Tour B330 and Bridgestone Tour B330-S across low, mid and higher ball speeds. The Z-STAR and Z-STAR XV overall distances were 2-4% lower when compared to the Tour B330 and Tour B330-S due to a lower launch angle and the higher spin for all ball speeds tested.

6-Iron Testing:

6-iron testing across all ball speeds for both the Z-STAR and Z-STAR XV exhibited less spin and slightly longer carry distance when compared with the new Titleist Pro V1 and Pro V1x at the highest ball speed level only. All other speeds in this comparison were similar. When compared to the Bridgestone Tour B330 and Tour B330-S, the Z-STAR and Z-STAR XV exhibited more spin and less carry distance at all ball speeds tested.

Sand Wedge Testing:

Both the Z-STAR and Z-STAR XV had notably more spin for a sand wedge than the Titleist Pro V1 and Pro V1x at all ball speeds tested but slightly more spin when compared to the Nike 20XI-S and 20XI-X. Launch angles were slightly lower across all ball speeds when compared to the Bridgestone Tour B330 and Tour B330-S as well as the Nike 20XI-S and 20XI-X and the Pro V1 and Pro V1x.

Bench Testing:

Our bench testing indicates that the Z-STAR has an overall compression reading of 93 points, which is about 5% higher than the overall compression reading of the 2009 Z-STAR. This reading is approximately 5% lower than the Titleist Pro V1 golf ball. The Z-STAR XV has an overall compression reading of 104 points, which is similar to the 2009 Z-STAR X. This reading is approximately 4% lower than the Pro V1x golf ball. Additional bench testing measuring cover hardness revealed that the Z-STAR was slightly softer cover hardness than the Z-STAR XV. Both golf balls exhibited slightly firmer cover hardness than both the and Pro V1x.

On-Course Player Comments:

“The Z-STAR feels softer than the new Nike 20XI-S and 20XI-X balls and comparable to the Bridgestone Tour B330 and Tour B330-S especially off the putter and sand wedge” – “When comparing the Z-STAR to the Z-STAR XV I seem to get more spin and feel around the greens with the Z-STAR XV although the Z-STAR seems to carry further.”

“The Z-STAR spins a little less than the new Titleist Pro V1. On approach shots, I liked the way the Z-STAR hit and released a little allowing aggressive shots without worrying about too much spin. Additionally I really liked the Z-STAR off my putter as it felt solid but not hard”.

Summary:

Golfers looking for a “tour ball” priced golf ball should consider the Srixon Z-STAR and Z-STAR XV golf balls. Golfers looking for a more penetrating ball flight off the tee may benefit from the lower launch characteristics of both of these balls. Additionally, both exhibited slightly more spin across all clubs when compared to other “tour balls”. The Z-STAR should appeal to golfers of all abilities with its slightly softer cover hardness and consistent spin across all ball speeds tested. The Z-STAR XV should appeal to golfers looking for a slightly firmer golf ball on and around the green.

In choosing the right golf ball, GolfBallSelector.com believes that golfers interested in the Srixon Z-STAR and Z-STAR XV should consider its “best fit” potential for their game in the context of their own preferences and the trade-offs they are prepared to take for distance, control and feel and according to their own unique ballistics measures of ball speed, launch angle and general spin rate. As with any ball, player preferences and individual launch/spin conditions are paramount. Learn more at GolfBallSelector.com, the #1 Ball Selector in Golf.
