VERDICT Callaway believes a flexible face isn’t enough. Adding structural stability allows the face to be thinner and concentrates that flexing across a wider area. So inside the head, two bars stretch from the crown to the sole. The extra stability makes for a face that’s 20-percent thinner and more flexible than before. The two models use a titanium frame with carboncomposite panels above and below. The standard version offers a sliding rear weight to address slices and hooks, and the Sub Zero’s two weights optimise ball spin. It’s Callaway’s most intriguing driver in two decades. Fourteen of our 16 testers put this club in their top five.
COMMENTS (L) It’s easily the most consistent driver, a controlled explosion at impact. (M) The adjustability is intuitive. (H) Power was colossal. Sound is muted, but there’s a strong carbon-fibre punch.
