2012 Goft Digest Hot List Gold Winner: Callaway RAZR X HL Super Game-Improvement Iron Set (Mid-March 2012) The Callaway RAZR X HL Iron Set takes accuracy, distance and foregiveness to new highs. Each iron in this set has a low center of gravity so golfers can launch shots higher, even on impacts low on the face, so golf balls fly consistently farther and land softer on the greens. This low center of gravity makes the sweet spot more accessible at lower impact locations, where many amateurs strike the ball, meaning more accuracy and consistent distance.
