The ‘Dual Runner Sole’ that was successfully introduced to Callaway’s FT hybrids has been added to a larger head in the form of the Diablo to provide more stability and forgiveness. The stainless-steel head has added weight in the perimeter of the head, making it easier to produce a high flight. The Callaway Big Bertha Diablo utility should suit golfers who prefer a utility to look like a small fairway wood and like a heavy head for added confidence.

The Callaway Big Bertha Diablo utility brought back memories of Callaway’s Heaven Wood series, which were in essence utility clubs before the term was created. The Diablo’s rounded head looked like a small fairway wood and worked extremely well from the tee box when the main priority was keeping the ball in play.
