Callaway Golf has solidified its XR line, now two years old, as its game improvement line, featuring technologies designed for maximum speed and distance.
The company teamed up with Boeing to improve the aerodynamic performance of its second generation XR driver and fairway woods, the XR 16. With the new XR irons and hybrids, dubbed XR OS for oversize, the idea is simple: longer and higher-launching clubs for maximum distance.
In the irons, the company improved their Face Cup technology to deliver more speed to the ball at impact. The club is also hit with two different heat treatments, one on the Face Cup to hike speed and a cooler heat on the body to improve feel. The whole package comes together on a wider sole design with a low-and-back center of gravity for maximum height and distance.
As is the case with most any game-improvement iron, the distance will go up compared to an iron built for a better player -- perhaps dramatically so -- but will come at the cost of dispersion. The XR OS irons will also sport stronger lofts, hoping to control against launching the ball too high.
