Brooks Koepka signed a new kit deal with Srixon at the end of 2021 and it was one of the biggest player moves of recent years.

The four-time major champion is also putting the all-new Srixon Z-Star Diamond golf ball on the line, aiming to build on his stellar PGA Tour career so far.

Alex reviewed the new ball and compared its performance to previous models such as the Srixon Z-Star and the Srixon Z-Star XV.

In terms of ball speed and spin rate, the Srixon Z-Star Diamond produces consistent numbers in both departments, similar to its predecessors.

This new ball was built with a FastLayer Core. They are soft in the center but get harder around the edges. The ball is suitable for players with faster swing speeds.

In this way, the Srixon Z-Star Diamond golf ball is suitable for tour players and should be avoided by mid to high handicap players.

This ball could be the direct competitor to the Titleist Pro V1 in 2022 due to the consistency of data Alex found at Silvermere Golf Club.

The main qualities are spin speed and the sound and feel of the clubface. These are the main improvements made by the brand.

The only concern Alex notices is with the putting. The ball is firm, which is a similar characteristic to the Z-Star XV.

Nevertheless, this brand new ball might be the best of 2022. The ball speeds and distances are fantastic and the feel is pure.
