The TaylorMade Rocketballz Iron Set is engineered to hit longer and straighter with more accuracy and better feel. The two-piece metalwood-inspired construction in these irons create a low center of gravity and a high coefficient of restitution (C.O.R.) while the ultra-thin face flexes freely to promote that C.O.R. up to the USGA limit for high ball speed. A re-engineered face with a new "Toe-Bar" controls face-flexion to direct shots straighter and the new vibration and sound control system promotes excellent feel and sound. This iron set incorporates a new ATV sole for maximum versatility and playability.
