Pros & cons

Pros

Best iron for protecting ball speed (4.4mph drop-off) and carry (6%) in 2020 GI category testing
7-iron carried 189yd — 3yd longer than the King F9 predecessor — with +1mph ball speed and 200rpm lower spin in reviewer testing
First iron to feature a carbon fiber topline — I-beam construction saves 3g for lower CG + 35% larger PWRSHELL sweet spot + 8% deeper undercut
Reviewers impressed with overall forgiveness particularly long irons — could feel technology within the head was helping on off-centre strikes

Cons

Feel at impact described as 'a little dead' — translates as poor feel through the body on contact
Some testers noted less of the crisp feel associated with forged irons — co-molded medallion only partially addressed sound concerns
Carbon fiber topline is polarising — 'opinions ranging from love to hate' at address
Now 5+ years old — superseded by Radspeed (2021) → LTDx (2022) → Aerojet (2023) → Darkspeed (2024) → DS-Adapt (2025) → KING (2026) lineage with refined feel/sound

Best for: Mid-to-high handicap golfers (12-28) at 78-105mph who want a 2020-era GI iron with best-in-test ball-speed protection + carbon-fiber-topline distance tech at clearance pricing.

Avoid if: You're sensitive to dead-feel hollow-body acoustic, dislike polarising carbon-fiber topline cosmetic, or want current-gen 3D-printed medallion damping (use Radspeed 2021 or newer Cobra GI).
