The Callaway Big Bertha Diablo irons combine a premium forged head with the modern styling that is common to the whole Diablo range. The irons combine a 455 carpenter steel face, providing a higher ball speed and shifting weight to the perimeter of the club, with a 1020 carbon steel body that provides a level of feel and feedback that the elite golfer demands. Unlike the woods, which are aimed at all levels of player, Callaway say the Big Bertha Diablo irons are aimed at elite players who want to combine modern technology and styling with a traditional feel and design that includes a thin topline and shorter blade. This they achieve with style and we really like the way the cavity blends into the back of the iron as you go down through the set.

The modern styling of the clubs and the distinctive Diablo graphics are hidden by the classic looks at address and right through the set the irons offer an excellent combination of power and playability to suit those lower handicappers searching for distance and the ability to shape their shots. Compared to the Callaway X-22 Tour irons the sole is a little thicker and the hosel a little longer which improves the Diablo’s playability. The forgiveness of the irons was better than the X-Forged, but not as good as the X-22 so the Diablo irons will be ideal for single figure golfers. The Diablo irons are available from 3 iron through to sand wedge and come with a graphite or a new Nippon steel shaft which is excellent and perfectly suited to this iron.
