Today, Ian and Mikey test out the new Mizuno ST-G Driver. A 440cc powerhouse featuring a newly optimized Fast Track design. Allowing adjustability ranging from a low spin bomber to a fade or draw bias or simply a more stable compact driver. This driver is designed to optimize launch and spin while enhancing ball speed through the innovative CORTECH Chamber. According to Mizuno’s Director of R&D, David Llewellyn, “The ST-G 440cc is very stable in the category of compact driver heads.

The addition of Mizuno’s CORTECH Chamber greatly influenced our ability to create more consistent ball speeds across the face.”
