Mizuno Golf makes some of the best irons in the world. Everyone knows that. But for a long time, Mizuno has languished when it comes to drivers and metalwoods. Part of that is the nature of their reputation as forged-iron gods, and part of that is a product lineup that has been confusing.
However, the company made the choice in 2017 to create two wood lines: ST for speed and forgiveness, GT for compact shapes and customization. So, for 2019, the ST190 and ST190G products are designed to build speed and keep the ball straight.
Mizuno ST190 and ST190G driver
Like with the ST180 line, the driver face is made from Forged SP700, which is stronger than 6-4 titanium and offers weight savings. It recovers more quickly from impact deformation to deliver more speed in a lower-spinning profile.
The carbon composite crown is lighter, coming in at 12 grams, and offered discretionary weight to place in the head for ball speed generation and less spin (a more forward profile).
Carrying through from the ST180 is the next generation of their sole wave technology, now called Amplified Sole Wave. The wave is designed to improve face flex and energy transfer across the entire face (and turf interaction in fairway woods). The depth and width of the grooves change moving back from the face toward the back of the head.
The ST190G model offers a dual Fast Track system, with toe and heel tracks each housing a 7-gram weight. The weights can further kill spin or be combined in a single track to create significant shot-shape bias.
The Mizuno ST190 driver will be available in February for $400 in 9.5- and 10.5-degree heads. The ST190G will be available in only a 9-degree head for $500. Stock shaft offerings center on Fujikura's Atmos line.
ST190 fairway woods
The fairway woods were built with a deeper, more driver-like face for more ball speed. The face insert is made of HT1770 Maraging steel while a carbon composite crown saved weight to help deliver a CG profile with low spin and a high launch.
The Amplified Wave Sole carries through, with a larger initial wave to offer forgiveness without jacking up spin rates.
The ST190 has a fixed hosel in 15- and 18-degree heads, but the ST190 TS (Tour Spoon) has an adjustable hosel to go from 13-17 degrees. The Mizuno ST190 fairway wood is available in February for $250 each, while the ST190 TS is $300. Both feature Fujikura Atmos shafts.
