Pros & cons
- Top of the 2021 game-improvement robot test on strokes-gained across long, mid and short irons.
- 115 mph 7-iron ball speed at 83 mph swing — fastest of the JPX 921 family in launch-monitor testing.
- Harmonic Impact Design delivers crisp acoustics and solid feel uncommon among cast distance irons.
- Stability Frame with toe-bias weighting protects ball speed on heel/toe strikes.
- Strong lofts produce fairly low launching and low spinning trajectories — may not hold demanding pins.
- Largest head and widest sole of any current Mizuno iron — looks thick to players coming from a players iron.
- Piercingly straight design intent leaves little room for shaping shots either direction.
