What’s new? How much does it cost? And how does it perform? Jack Backhouse brings you the low down on the Srixon 2025 Z-Star Diamond golf ball.

In a competitive market where performance golf balls must walk the fine line between distance and feel, the Srixon 2025 Z-Star Diamond takes aim at players seeking pinpoint control without sacrificing distance. So, we put the latest iteration to the test, and here’s what we found…

5 star review
NCG SUMMARY

The Srixon Z-Star Diamond is a premium three-piece golf ball built for players who demand spin, control, and a responsive feel, particularly when playing into the greens. Offers strong short-game performance and softer feedback than its predecessor. While it doesn’t fly the furthest, especially off the driver, it excels in shot-making precision. A standout option then for mid-to-low handicappers who value feel and control above all else.

PROS

  • Tour-level stopping power
  • Noticeably softer feel than previous generation
  • Excellent putter feedback

CONS

  • Requires moderate-to-fast swing speed to get the best performance

Srixon 2025 Z-Star Diamond Golf Ball Review: First Impressions

The Z-Star Diamond is a three-piece, tour-level ball that features some notable upgrades over its predecessor. Srixon has reengineered the core, making it softer and enhancing the feel, particularly around the greens. The older version was often bit harsh around the greens, but that issue seems to have been well addressed in this model.

Another standout is the thicker urethane cover, enhanced with Srixon’s “Spin Skin with SeRM”. This is a proprietary coating that promotes increased friction at impact. This allows grooves, especially on wedges, to grab more aggressively, leading to greater spin generation.

NCG Verdict

I think the biggest leap forward is undoubtedly in greenside control. The feel was softer than its predecessor, which was a welcome change. When I tested it with a wedge, spin rates clocked in at a whopping 7,600 rpm with a low launch of 27.7°, which were ideal characteristics for stopping power and finesse shots.

On the putting green, I thought the feedback was equally positive. The ball felt softer and more responsive than expected, without sacrificing consistency. This kind of balance is ideal for confident lag putting and touch shots.

With hitting my 7-iron, the Z-Star Diamond was very promising and showed exceptional spin rates around 6,700 rpm, offering tour-level control into greens. However, that came at the expense of distance. My recorded ball speeds of 116 mph, resulting in a carry of 159 yards and a total of 167 yards were some of the shortest numbers I have recorded during recent golf ball tests.

Although, this performance trade-off will suit players who prioritise approach shot control over sheer length. Again, high spin players or those seeking to flight the ball with precision will find these characteristics a plus.

Off the tee, the ball maintained reasonable ball speeds at 160 mph, but spin crept up to 2,800 rpm, which is a tad high for a maximised carry yardage. The result? A carry of 271 yards and a total distance of 287 yards.

It was clear during testing that this ball is best suited to players with decent clubhead speed, who can compress the ball efficiently and unlock its full potential. Slower swingers might find it slightly underpowered in the long game.

Final Verdict

Overall, the Srixon 2025 Z-Star Diamond is a high-spinning and control driven golf ball best that offers tour-level performance. It rewards those who prioritise feel, control, and approach consistency, but won’t be the go-to choice for those looking to squeeze out maximum distance.

If you’re a strong iron player looking for extra bite into greens, and you’ve got the speed to match, this could be a game-changing fit.

Callaway Epic Max driver review
Jack Backhouse

A member of the PGA for 13 years, Jack has lived golf for more than half his life. Inspired by Tiger Wood’s winning putt at the 2008 US Open, an obsession began with watching slow motion golf swings on the internet and reading What’s In The Bag articles in magazines.

Not destined for a life behind the desk in a pro shop, Jack has focussed more on coaching, working closely with regional teams in North Yorkshire and helping golfers of all levels on their journey to enjoying playing the game more. Jack has coached many junior golfers into the county teams, and once worked with a player at the 2018 Open Championship at Carnoustie.

After letting his game fall apart prior to COVID, Jack rediscovered his love for playing golf after joining Silloth Golf Club in 2020 and whipping round the windy, firm links course. Playing regularly with a half set of clubs he has a passion for shot making and developing skill, and claims to have the sharpest 30-100 yard game in the North of England (only because he doesn’t know anyone in the South), and now maintains a +1 handicap at a club much closer to home, Sand Moor GC.

Jack has always tinkered with his equipment, once building his own Frankenstein one length set of clubs after watching Bryson DeChambeau burst onto the scene after winning the US Amateur. He firmly believes in getting custom fit and is happy to debate anyone about blade irons being superior to any other iron category.

Jack loves: playing quickly, 2 ball golf, match play, heathland courses, pencil bags, foursomes, Tiger Wood’s swing 2005-2009.

Jack hates: buggies, unnecessary trees, giving shots, the 7 iron loft debate, graphite shaft lovers weird superiority complex.
