ST-Max 230
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
You're a 8-30 HCP at 80-110mph who needs maximum hybrid forgiveness above all else — 2nd-place MyGolfSpy robot-test forgiveness ranking + largest MOI in ST Woods history makes this a top-tier off-center performer; comfortable trading some outright distance for class-leading retention.
You want maximum total carry/distance from your hybrid, you want a sleeker tour-shape head, or you need shape-shifting workability.
Pros
- Industry testing: 2nd overall in forgiveness scoring in 2024 Most Wanted Hybrid robot testing
- Largest sweet area (MOI) in ST Woods history — CORTECH Chamber shifted closer to face for both center and off-center ball speeds
- Independent testing: 19° model produced 236yd carry while offering excellent forgiveness
- Speed Bevel leading edge + Waffle Crown ultra-lightweight construction — easy launch from tee or turf
Cons
- Ranks towards the bottom for carry and total distance relative to other 2024 hybrids — distance is not its primary strength
- Larger footprint + low/deep CG = straight-flight GI design — limited shape control
- Geared for mid-to-high HCP — won't suit a low-HCP player wanting a sleeker tour-shape hybrid
- No movable weight system — adjustability limited to Quick Switch ±2° loft sleeve
By dimension
Forgiveness
Industry-test 2nd overall in forgiveness scoring in 2024 Most Wanted Hybrid testing. Largest sweet area (MOI) in ST Woods history ensures forgiveness and consistency, even on off-center hits. CORTECH Chamber, shifted closer to the club face, increases both center and off-center ball speeds. Maximum forgiveness with a larger footprint. Top-tier forgiveness — 2nd-place industry robot ranking + largest MOI in ST Woods line + CORTECH off-centre ball-speed preservation.
Distance
Independent testing: the 19° model produced carry distances reaching 236 yards while offering excellent forgiveness. However, relative to other hybrids tested, the ST-Max 230 ranks towards the bottom for carry and total distance — distance is not its primary strength compared to other 2024 models. High energy MAS1C steel face is enhanced by an expanded CORTECH Chamber. Average distance — strong 236yd 19° carry but robot testing ranks the head near the bottom of 2024 hybrids for total distance.
Workability
Weight located low and deep and an ultra-lightweight waffle crown combine to deliver an impressively straight, predictable ball flight. Larger footprint designed for handicap golfers with a lower profile. GI/max-forgiveness profile. Below-average workability — explicit straight-flight, max-MOI GI head design with limited shape control.
Feel
CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU, taking stress from the club face and creating an additional energy source, while locating weight closer to the club face to reduce spin rates and contributing to a more solid, powerful sensation at impact. Classic Mizuno look remains — premium Mizuno feel DNA. Above-average feel — CORTECH-engineered solid powerful impact, classic Mizuno feel tradition.
Sound
CORTECH elastomeric TPU damping contributes to solid impact sensation. Classic Mizuno look remains — implied premium acoustic profile consistent with the brand's tradition. Reviewers don't single out the sound as either a standout or a weakness. Average to above-average sound — TPU-damped CORTECH delivers a controlled Mizuno-signature acoustic, no reviewer concern but no standout praise either.
Looks at address
Classic Mizuno look remains while small refinements have improved forgiveness compared to predecessor. Larger footprint and lower profile. GI larger profile for confidence. Above-average address — classic Mizuno aesthetic + larger inviting GI footprint with low profile.
