Pros & cons

Pros

+1.8mph ball speed avg + 3-6yd extra carry vs 2025 Elyte — measurable distance gain
Best feeling cast GI iron tested in 2026 — truly soft and luxurious experience
Modern 360° Undercut Cavity + extreme perimeter weighting + AI face for class-leading GI mishit support
172yd 7-iron carry + 198yd 5-iron carry at 4700rpm / sub-3500rpm spin

Cons

Loud uniform acoustic robs the mishit feedback channel
Less refined than 2025 Elyte at address — visually busier
29° 7-iron + 360° undercut + cavity back = high-launch straight bias
Distinguished GI competitor field (Srixon ZXi, TaylorMade Qi, Ping G440) makes the decision tough for high HCPs

Best for: A 10-24 HCP at 80-105mph who wants the longest, best-feeling cast GI iron of 2026 with class-leading mishit support — and isn't bothered by loud uniform acoustic.

Avoid if: You're sensitive to loud impact acoustics, you want shotmaking, or you already game Elyte 2025 (incremental upgrade — wait a generation).
