Out of all the drivers I tested, the Srixon ZX5 Mk II was the most forgiving. It was also one of the hottest. This driver’s Rebound Frame has two flex zones, while most drivers only have one.
At the top end of his iron set, Echavarria goes with the Srixon ZX5 Mk II for both his 4- and 5-irons. While the 0317s are more about precision and control, the ZX5s are more distanced-focused.
