Improvement is the goal for anyone in the golf industry and Srixon is no exception. In 2010, the Srixon released the first Z-STAR XV golf ball. Thus began the Z-STAR series’ journey to where it is today. The latest versions of the Z-STAR and Z-STAR XV blend new design elements, giving more tour-level performance over previous models. After discussing each improvement, you’ll see how Srixon is true to their word.
The Z-STAR is a 3-piece ball and is ideal for swing speeds of 90+ MPH. The ball has a softer feel compared to the previous Z-STAR. To accomplish this, Srixon redesigns their proprietary Energetic Gradient Growth core. This core starts soft in the middle and gets increasingly harder moving towards the outside of the ball. Reducing the compression to 88 improves launch conditions and gives more distance off the tee.
The cover of the Z-STAR has a 338 speed dimple pattern. There are 5 different dimple sizes that give the ball longer, more efficient flight. These dimples make up Srixon’s trademark Spin Skin Coating. The improved version on the Z-STAR increases friction due to fewer bonding points between the club face and the ball. More friction leads to more spin, especially around the green and out of the rough.
In contrast to the Z-STAR, the Z-STAR XV works best for swing speeds above 100 mph. The 4-piece ball has a firmer feel than the Z-STAR, with a compression of 105. The Z-STAR XV launches higher than the Z-STAR and also delivers low driver spin.
The new dual energetic gradient growth core in the Z-STAR XV has a larger, softer inner core. The outer core has more consistent hardness. The ionomer mid-layer, located just below the Spin Skin coated cover, is thicker than before. The Z-STAR XV also has the same 338 speed dimple pattern as its counterpart. These elements combine to deliver maximum ball speed and distance on full shots and exceptional spin around the green.
Feel and swing speed are the biggest differences when comparing the Z-STAR and Z-STAR XV. A moderately fast swinger, looking for softer feel and the most spin around the green should stick with the Z-STAR. Fast swingers that want the most distance while sacrificing a little spin and softness will want the Z-STAR XV.
