In terms of its many features, among the most notable is that the center of gravity on the OS has been moved lower and deeper to dramatically enhance launch angles. The incorporation of Face Cup technology, meanwhile, creates incredible distance to go along with the higher launch conditions created by the CG placement.
Additionally, the Face Cup in the XR OS has undergone a specialized heat treatment that generates even faster ball speeds while also promoting better feel. The soles are also a little bit wider, making XR OS easier to hit from any number of lie conditions, and a unique progressive length and loft system has been designed to improve performance with each club through the set.
In terms of how XR OS compares to Callaway’s other 2016 iron offerings, Manager of Tour Fitting John Degen said, “It has the most offset, it’s the longest blade, and it’s for players looking to get the ball in the air with maximum distance.” Callaway offers lightweight options in both graphite and steel as a stock shaft, but other options are available as well.
“Maximum forgiveness as far as our product line. It has the most offset, it’s the longest blade, and it’s for players looking to get the ball in the air with maximum distance.” John Degen – Callaway Manager of Tour Fitting
“Nothing wrong with going farther and being more forgiving in my view.” – Baber, TGW Customer 5 hdcp.
