ZX4
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
You're a mid-to-high handicapper (or a slower swing) who wants maximum forgiveness, easy high launch and serious distance in a relatively clean, midsize package.
You want workability, traditional lofts and feel (the ZX5 or ZX7), or you already flight your irons well.
Pros
- The most forgiving iron in the ZX family - a hollow body from long to short iron expands the performance zone
- Very long - high-density tungsten lowers CG for a high launch, with a fast MainFrame face
- A forged HT1770 face with a MainFrame variable-thickness pattern maximises ball speed across the face
- A 431 steel body absorbs vibration for the feel of a forged blade in a forgiving package
Cons
- A high-launch distance iron with strong lofts - low on workability and shot-shaping
- A hollow game-improvement build - more for forgiveness and distance than feel or control
- Strong lofts for distance, not traditional gapping
By dimension
Forgiveness
The most forgiving ZX - hollow from long to short iron, the most forgiving in the ZX family, the hollow body expanding the performance zone, with chunky, high-MOI off-centre dependability. Strong game-improvement forgiveness.
Distance
Very long - high-density tungsten lowers CG for a high launch and strong, fast distance, the MainFrame variable-thickness face maximising ball speed across the face. Elite distance, several yards longer than the already-long ZX5.
Workability
A distance iron, not a shaper - a forgiveness-and-distance hollow iron that flies high and straight, the chunky, high-launch build going straight rather than working the ball. Limited workability, as expected of a game-improvement iron.
Feel
Soft for a distance iron - the 431 stainless body absorbs vibration to deliver the feel and versatility of a forged blade in a forgiving package, the forged HT1770 face adding a soft sensation. Excellent feel for a hollow game-improvement iron.
Sound
Solid, lightly hollow - the 431 body keeps the note solid rather than clicky, with a slightly hollow, fast-faced acoustic typical of the build. A clean if slightly hollow sound for a distance iron.
Looks at address
Sleek for a GI - a sleeker profile and thinner sole width that moved it from super-game-improvement into game-improvement, with a midsize, relatively clean shape. Clean for the category, but visibly a game-improvement iron with offset.
