TaylorMade RocketBladez Tour Individual Iron with Steel Shaft With the TaylorMade RocketBladez Tour Individual Iron with Steel Shaft, 11 grams of weight is redistributed strategically in order to lower the center of gravity location, promoting a higher launch angle, higher peak trajectory, and a steep, soft-landing, quick-stopping descent angle. Consistent distance with every iron is made possible by careful management of the Speed Pocket, improved Inverted Cone shape, and high MOI. The Speed Pocket offers a consistently high ball speed and longer distance, and the fantastic feel comes from a specially formulated polyurethane developed by 3M that fills the Speed Pocket and quiets vibration. A milled face-texture and grooves allow for consistently high spin.
