TaylorMade RocketBallz Speed golf balls were engineered for the golfer that desires powerful distance, a responsive feel, and great value. This golf ball has a tremendous amount of speed - the fast REACT core stores and releases energy after impact for big distance while still maintaining a soft feel. The RocketBallz Speed has 82 compression construction and is built for those golfers looking for maximum distance off the tee. But TaylorMade knows that distance isn't the only thing that matters. The Ionomer cover of the RocketBallz speed golf balls provides responsive short game performance for a soft feel into the green. Simply put, the RocketBallz speed can be summed up in three words: Powerful. Playable. Distance.
