Callaway Diablo Edge irons

What impressed most about this game-improvement set was the shot dispersion, regardless of the type of strike. Long-iron shots caught slightly fat on a soggy day still flew similar to that of a good strike. For an all out forgiveness set of irons there was an impressive soft feel off the face. The irons gave impressive forgiveness on soggy ground thanks to the thick sole and large cavity. A soft feel off the face of the irons was a pleasant surprise. The cavity can be seen at address in the long irons, which was slightly off-putting. These are not ideal for those looking for a lower flight. (Tested by GM's Paul O'Hagan & James Mason) PGA Pro verdict Unmistakably a relative of the Big Bertha. The wedge head looked quite small and compact, with strong loft. The wide sole was forgiving through the whole set, but the 3-iron looked almost too strong in loft; I would recommend the utility replacement option. By keeping the traditional features and benefits it is one of the best game-improvement irons on the market. (Tested by John Jacobs)
