The Verdict: The premise is wickedly simple: To make a faster-flexing face, why not make it illegal to start? Then, before the head is finished, tune it back to being legal. The execution isn’t so simple, of course. The heads are injected with a precise amount of resin (through those blood-orange ports) to make them as close to the conforming limit as possible. TaylorMade says it has increased the area of the face at the USGA limit to nearly the size of a quarter. Also, two 10-gram weights in a T-shape track on the sole control ball flight in thousands of possible settings.
