ST-Z 230 / ST-X 230 / ST-X 230 PLTNM

Hot List Gold 2023

Our Review:

WHAT IT DOES: A fast-flexing titanium-alloy face has been a point of pride for Mizuno, but that technology can take you only so far. Real progress is made when the rest of the body contributes to the face’s ability to deliver more ball speed. A cut-through slot in the front of the sole is filled with a polymer that allows more flexing in the lower part of the face. A five-gram steel bar inserted into the polymer lowers spin further to optimize launch conditions.

WHY WE LIKE IT: The multilevel face-thickness pattern creates more consistent ball speed across a wider area and is further enhanced by the weight-saving carbon-composite crown and sole sections. A heavy back weight also provides stability on mis-hits. Read more>>>

Which One's For Me?
ST-Z 230
The ST-Z features a deeper, more neutral center of gravity for less spin and maximum mis-hit forgiveness.
ST-X 230
Placing additional mass toward the heel on the ST-X encourages a draw and offers players a better sense of control or where the clubhead is at all times.
The ST-X PLTNM version is 30 grams lighter to help slower swingers deliver more speed at impact.

Player Comments
“The sound at impact has a deeper note than I would have expected. Easy to launch with a penetrating ball flight.”
Handicap, 15
"It feels like one of their forged irons. Great feedback. just feel the ball explode off the face. Boring ball flight, doesn't get too spinny, so you can either lay off it or go after it."
Handicap, 6
"Such an enjoyable sound and flight on every shot. Above average in terms of distance. Love the shell look on top. Overall a very attractive club."
