Relative to category peers · methodologyPros & cons
- Forgiveness on mis-hits is extremely good — reviewers often had trouble distinguishing mis-hits from solid strikes by ball flight alone; excellent face-top/bottom recovery rare for the GI category
- Matched 37.5" length + head weights + swing weights — promotes one repeatable setup and swing for consistency and accuracy
- Inherits 2021 Radspeed chassis: PWR Shell 17-4 stainless face + RADIAL weighting (10g toe + 3g heel) + 3D-printed medallion
- Fine-tuned lie angles + progressive shaft weighting promotes high launch and forgiveness in long irons and lower launch with more control in scoring irons
- Reviewer testing: 'the ugly carbon fiber topline is distracting from an otherwise beautiful club head' — explicit aesthetic downgrade
- OL silhouette categorical penalty at address — long irons appear stubby and short irons appear stretched
- Same strong-loft + low-spin + flat penetrating ball-flight character as standard Radspeed — limited stopping power on firm greens
- Now 4+ years old — superseded by LTDx (2022) + Aerojet (2023) + Darkspeed (2024) + DS-Adapt (2025) + KING (2026) lineage
