This Taylor Made RAC Mirror Wedge features conforming 2011 grooves, these Tour-Proven 100% Y-cutter grooves use a milled manufacturing process that offers a clean, sharp, consistent groove edge that grip the of the ball more effectively to consistently deliver up to 300 additional RPM than Taylor Made's Dual-Draft grooves, resulting in enhanced bite & control from shot-to-shot. With tour development the Tour-Proven Sole Configurations give a tour-configured sole that is ground low on the trailing edge & at the toe & heel. When viewed from above, the trailing edge appears curved, resembling the letter C. This sole configuration allows players to open the clubface around the green to play high, soft chips & pitches. The leading edges of all the rac wedge models are radiused, enhancing the player's ability to hit low punch shots without digging. The versatility created by both the low trailing edge & the radiused leading edge make it possible to hit an extraordinarily wide variety of greenside shots with only a single bounce configuration.
