If you are either a game improver, slow swinger, not very accurate or need more forgiveness then the Callaway XR OS irons are aimed at you.
They offer a larger and more forgiving version of the Callaway XR iron and as a result can feature a lot of the same design features that make their woods easier to hit.
The main one is the second generation of iron Face Cup that sees the face wrap around the front of the club to enable it to increase the ball speed as the weld lines to be behind the face rather than on it.
The larger head allows for a bigger cavity behind the face and a thinner sole area on the bottom of the face cup enables it to flex more at impact for greater ball speed cross more of the face.
As you would expect the XR OS has a wider sole than the XR, but the trailing edge is raised up so that it does not affect the playability at impact.
Having this extra weight here moves the Centre of Gravity (CG) lower and back than the XR to make the XR OS easy to get the ball airborne.
What was pleasing at impact was the trajectory which was on the mid to high side without ballooning up. The look at address is on the chunky side with a thick top line and decent offset.
However it is a very clean look and whilst it is large, I did like the fact that this does not shout the fact that it is a super game improvement iron.
It actually plays like a 'normal' forgiving iron and the feel from the middle gave the impressions that some mid handicappers might want to use this, particularly in the long irons.
The XR OS irons have been designed in conjunction with the Callaway XR OS hybrid so that the two can be blended together to create single set from the 5-iron upwards.
This option together with the clean looks and mean that if you are looking for some oversized help with your game, then the XR OS irons will deliver it large.
