• Rogue ST features four new game-improvement iron sets.
• All four feature 450 Face Cup designed by AI.
• Up to 62 grams of tungsten have been added to lower the CG

But if you’re not into the whole brevity thing, Rogue ST is a roadmap to Callaway’s iron strategy going forward. Callaway now boasts 12 to 16 distinct iron sets, depending on how you define combo sets. With that many, you can exercise control over retail space and consumers’ attention. If you can’t find a Callaway iron to fit your game, then golf might not be for you.
