In this buying guide, we've enlisted Mark Crossfield to give us the lowdown on the Callaway XR SteelHead Pro Irons.
The most striking feature you will immediately see is the darker finish of the irons. You might also recognise the style of the irons as they are a modern take on the iconic Steelhead irons of the yesteryear.
In the pro version, there is a slight offset in the head and a medium thickness in the top line which makes this pro model quite forgiving. Mark found that the iron is one of the longer irons he has tested and they had impressive consistency across the face.
