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.

We think they have achieved this 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.

From the look, it's funky design and large sole don't seem to be hard to hit. But, when you take the club at address you will slowly realize why it's designed for low handicapper. The cavity back design really helps to reduce the vibrations. Further more, it's soft body and hard face really promote a penetrating trajectory ball flight (play like FT-i irons). I played with the NSPRO stiff shaft and that makes the swing looks perfect as the light steel shaft works with the cavity back design and hard face. The result is forgiving! forgiving! forgiving! Unbelievably forgiving for a player's iron. The only draw back is workability. Compared to the X22 tour, I have to put some effort in to shape the short. However it's just the matter of time on the range.

I found the Big Bertha Diablo irons a tad strange because, unlike the woods in the range, they seemed to be aimed purely at the better player. That said though you can certainly tell this is a quality club that will deliver consistently for you. Which just leaves the looks: Callaway's graphics people have gone to town on the whole Diablo range. If you don't like the look then they might not be for you - if you can stand it then you'll get a cracking set of irons!
