TaylorMade's Tour Response is designed to deliver fast ball speeds, tour performance standards at a lower price. Easy to play, easier to afford. The TaylorMade Tour Respone golf balls is similar to TP5/TP5x and designed to deliver fast ball speed. A soft, cast urethane cover allows the grooves of the wedge to better grip the golf ball for increased green-side spin, A crosslinking chemical reaction forms the urethane material, which creates an irreversible link for improved shear resistance and greater durability. A core made from soft flexible materials with increased elastic components delivers better and softer feel with an ultra-low 40 compression. A firmer second layer surrounds the soft inner core and allows for an explosive transfer of energy and increased ball speeds.
