This mainstay of the Srixon golf-ball family has been around for more than two decades and is in its 12th version. To increase distance this ball has a gradation core that is softer in the centre before gradually turning firmer towards the perimeter. The design delivers more rebound at impact off the longer clubs. For the ionomer cover, a 338-dimple pattern is used to help downrange flight as it enhances lift with reduced drag, a combination that results in more carry distance by keeping the ball in the air longer. The overall compression of 60 is about a third less than the Z-Star, the company’s softest tour ball, and the thin ionomer cover provides enough greenside spin to matter.
