The Callaway Mack Daddy 3 Milled Black Wedge has the versatility needed for every shot, every course condition, and every swing. Its the most complete wedge that Callaway has ever created. By leveraging three unique grinds (S-Grind, C-Grind, and the new W-Grind), the new milled Progressive Groove Optimization system optimizes spin for each loft, and advanced shaping and design allow you to specialize a wedge to your game and all the shots that you want to hit. Legendary wedge designer Roger Cleveland received extensive input from Tour players, and he used their feedback to craft the toe profile, sole, and grinds. This wedge gives you everything you need to get up and down from anywhere. Three Grinds For Every Shot, Every Condition, and Every Swing Callaway developed three unique grinds to suit the shots you hit, the courses you play, and the swings you make. Its the versatility and selection you need to get up and down from anywhere. W-Grind: A slightly wider sole. Its perfect if you play in softer conditions or you come in with a steep angle to the ball, and its extremely playable out of all types of bunkers. S-Grind: Callaways most versatile option. Its great for a wide range of conditions (normal, soft, or firm), shot types, and swings (moderate to sweeping attack angles). C-Grind: Designed for firmer conditions and versatility around the green. The heel and toe relief allow for a number of shots, especially opening up the face and keeping the leading edge low. Progressive Groove Optimization The Mack Daddy 3 Milled Wedge has Progressive Groove Optimization – a three-groove package precision milled into the face of the wedge that optimizes spin as you go up in loft. It creates a smoother spin transition from your irons to wedges. The 30V grooves in the Pitching and Gap Wedges are built for shots that require a steep angle into the ball. The 20V grooves in the sand wedge is designed for full shots and bunker shots, and Callaway put in wider 5V grooves in the lob wedges for better control for shots out of the rough and around the green. Advanced Shaping and Design Legendary Callaway wedge designer Roger Cleveland took Tour input and blended that with advanced CAD design. The result is a balanced wedge with a high toe profile and a semi-straight leading edge. The weight ports in the back of the wedge gave the freedom to reposition the weight for better shot-making, especially out of deep rough.
