Pros & cons
- 3D-printed medallion saves weight and optimizes feel — Cobra's first 3D-printed iron part introduces a notably softer feel vs typical 2021 hollow-body GI irons
- Nearly 2mph faster ball speed + fractionally higher launch + less spin + good stopping power vs Speedzone predecessor — +5yd extra carry per reviewer testing
- RADIAL weighting (10g toe + 3g heel) + PWR Shell 17-4 stainless face delivers speed + low spin + stability combination
- Super long and forgiving — fast face and high launch compensate for strong-loft stopping trade
- Strong lofts and low spin limit stopping power to a small degree — flat penetrating ball flight typical of distance-tilted GI
- Sound was quite loud and high pitched — reviewers flagged as a slight downside
- Standard GI silhouette + strong lofts + low spin = limited shot-shaping; reviewers don't highlight workability
- Now 4+ years old — superseded by LTDx (2022) + Aerojet (2023) + Darkspeed (2024) + DS-Adapt (2025) + KING (2026) lineage
