Mizuno ST-G Driver Review | Golf Monthly

The fruits of Mizuno’s “Speed Technology Metalwood Project” over the past few years led us to the ST-230 series. Until now, this included the ST-Z and the ST-X. Now we have a new member of the family, the ST-G. 

The ST-G is a 440cc head driver, targeted more at the lower handicap player. Although with the adjustability of the two convergent weight tracks, Mizuno says that the ST-G can be anything from a low-spin bomber, fade or draw biased or simply a more stable compact driver.

The ST-G features the same cortech chamber as the other two drivers in the range, which encases a stainless-steel weight with elastomeric TPU. This cortech chamber was designed to take stress from the clubface and create an additional source of energy. In addition to this, Mizuno engineers say this pushes weight closer to the face to reduce spin, while also contributing to a more solid, powerful sensation at impact.

The ST-230 series are some of the best-looking drivers on the market and the ST-G might just be the pick of the bunch. We know that beauty is in the eye of the beholder, but to me the shaping of this head is near perfect. I have always preferred a deep face in driver and the ST-G certainly delivers that. Something about the dimensions of the more compact overall 440cc head makes it seem even deeper than it actually is. When compared to a Taylormade Stealth 2 Plus for example, the depth is similar, yet the Mizuno driver somehow feels deeper, which to me at least is great. 

The gloss black finish of the crown starts as a solid block close to the top edge but blends into a sleek carbon effect as it moves back. The Mizuno logo is useful as a marker to center the ball but is subtle in grey. For me, it is difficult to imagine a more premium-looking driver than this.
