The Callaway Diablo Edge irons are the longest and most user friendly irons that Callaway have produced and build on the appeal and playability of the now iconic Big Bertha irons.   As part of their commitment to amateur golfers Callaway have been busy studying exactly how best golf clubs ordinary golfers strike the ball. The results led Callaway’s designers to drop the centre of gravity in the Diablo Edge golf irons 50% lower and 17% deeper to move the sweet spot to the exact area where most golfers will hit most of their shots. The relocation of the centre of gravity has also allowed each Diablo Edge iron to have a one degree stronger loft to maintain the height of the ball flight.  
A new Solid Impact Sole design allows the Callaway Diablo Edge to slide through the turf more efficiently and reduce the impact of any thinned shots. The Diablo Edge irons are confidence building clubs but if you do need an extra boost then the longer irons can be replaced with the Diablo Edge hybrid from the six iron upwards.   We were impressed by the Big Bertha Diablo irons when they were launched so we were keen to get our hands on the new Callaway Diablo Edge irons. We like the styling and the graphics and our only quibble with the appearance of the Diablo Edge irons is that the short irons can look a little chunky and the large cavity in the longer irons is visible at address. This has also been a problem in the Big Bertha irons but it is only a small complaint and it doesn’t affect performance.   The performance of the Callaway Big Bertha Diablo Irons is excellent and you can really feel the extra power generated by the slightly stronger lofts. With the sweet spot lowered it takes little effort to get Titleist CB 712 Irons the ball and airborne and we’re really impressed that all Callaway’s research into amateur golfers makes such a big difference to the performance. We were similarly impressed by both the standard and tour versions of the Diablo Edge hybrid but we’d certainly recommend that better golfers persevere with the longer irons. Even the 2 iron is wonderfully forgiving with the advantage of a lower ball flight compared to the hybrid equivalent.  We were impressed by the Big Bertha Diablo irons when they were launched so we were keen to get our hands on the new Callaway Diablo Edge irons.
