Shane Lowry is one of Srixon's most well-known Tour players. He plays with Srixon Z-Star XV and has found Tour and Major success with these golf balls.

338 Speed Dimples THIN, PREMIUM COVER: Every Z-STAR Series golf ball features an extra thin, thermoplastic urethane cover to provide tour-level stopping power around the greens. SPEED DIMPLE™ PATTERN: With their deep dimensions, the 338 Speed Dimples on each Z-STAR Series golf ball punch through the air for a penetrating launch.

Whilst both are extremely good options, The Titleist Pro V1 remains the benchmark that all other premium balls will be judged against. The Z Star will be a good choice for those who like softer feel golf balls and a bit more spin than the Pro V1.

Srixon said the standard Z-Star has the softest mid-layer and lowest overall compression, providing the softest feel at impact. In contrast, the Z-Star XV ball has a soft core that is drastically firmer around its outer area for more distance and long-iron spin.

The softer Z-Star is designed for approach shot and maximum greenside spin, the firmer Z-Star ♦ (Diamond) aims at iron spin control and distance and the Z-Star XV mixes a softer central core with a very firm outer region to maximize ball speed for the most aggressive swing speeds.

Which one's for me? The Z-Star XV features the thinnest cover and firmest compression. It targets players with higher speeds who are focused on distance. The standard Z-Star has a lower compression and a 20-percent thicker cover (0.6 millimeters vs.

Srixon says its testing shows the Diamond is nearly two yards shorter than the XV (at 112-mph swing speed) but with higher driver, iron and greenside spin than the XV.
