The Verdict: Callaway's belief that higher-handicappers need the most help with the low and middle irons is evident here. The Big Bertha OS features tungsten in the sole to lower the center of gravity (CG), which promotes getting the ball airborne. The short irons don't need the help launching the ball, which is why the CG gets progressively higher in those irons for increased control. The revamped cupface (in which the face wraps around the topline and sole to help it flex more) functions more efficiently in the low and middle irons.
