Srixon · Irons · 2023
ZX4 Mk II
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
You're a mid-handicapper who wants a forgiving, accurate, great-feeling iron with a surprisingly clean look - or a better player who wants extra help in the long irons.
You're chasing maximum distance (the original ZX4 or a dedicated distance iron), or you want workability and traditional lofts.
Pros
- A complete makeover - the chunky hollow hybrid-iron is gone, replaced by a clean, compact cavity-back look in line with the ZX5 and ZX7
- Rated the best game-improvement iron of 2023 for feel, sound and looks, and 2nd overall for accuracy
- 4th overall in 2023 game-improvement robot testing, with top-4 forgiveness from a hollow, high-MOI body
- Easy, high launch and a forgiving, confidence-inspiring profile for mid-handicappers
Cons
- Distance is the weakness - 8th for distance and 7th for ball speed in robot testing, a step back from the original
- Strong lofts (up to 2.5 degrees stronger than the ZX5) for distance that doesn't fully show up
- Not for high handicaps - aimed at mid-handicappers or better players wanting long-iron help
By dimension
Forgiveness
Top-4 in the category - robot-tested 4th for forgiveness and 2nd overall for accuracy, the hollow body boosting MOI across the face, with uber-forgiving off-centre performance. Elite game-improvement forgiveness.
Distance
The surprising weak spot - robot testing found distance to be the biggest weakness, finishing 8th for distance and 7th for ball speed, a step back from the original, even with lofts up to 2.5 degrees stronger than the ZX5. Mid-pack distance for a game-improvement iron.
Workability
A touch more shapeable - a forgiveness-first game-improvement iron that flies high and straight, though the cleaner, less-offset profile gives the better player marginally more control than the original. Limited workability, slightly above the first generation.
Feel
Best feel in its class - rated the best game-improvement iron of 2023 for feel, the 431 stainless body and hollow construction giving a soft, solid sensation. Class-leading feel for a game-improvement iron.
Sound
Best sound in its class - rated the best game-improvement iron of 2023 for sound, with a muted, solid note and no hollow click. Class-leading acoustics for a hollow game-improvement iron.
Looks at address
A complete makeover - rated the best game-improvement iron of 2023 for looks, the chunky hybrid-iron with bags of offset replaced by a clean, compact cavity-back in line with the ZX5 and ZX7. One of the best-looking game-improvement irons of its era.
