Relative to category peers · methodologyPros & cons
- Reviewer testing called this 'one of the most forgiving iron sets that money can buy' — forgiveness particularly strong in the long irons
- Inherits standard Speedzone chassis: 35% larger PWRSHELL sweet spot + 8% deeper undercut + first-ever carbon fiber topline I-beam construction + co-molded medallion damping
- Matched 37.5" length + progressive shaft weighting that gets steadily heavier as irons get shorter — exceptional setup repeatability
- Bryson DeChambeau connection — OL design philosophy delivers GI-class distance with the 27.5° 7-iron strong-loft profile
- Reviewer testing flagged that 'consistency in distance is a lot wider than desired, with odd shots that suddenly fly 15 yards further than expected'
- Sound and feel weaknesses inherited from variable-length chassis — 'a little dead at impact' + 'less crisp feel than forged irons'
- Polarising carbon fiber topline cosmetic — 'opinions ranging from love to hate' + OL silhouette categorical penalty
- Now 5+ years old — superseded by Radspeed OL (2021) + Darkspeed OL (2024) lineage with refined feel/sound damping
