The Callaway Opus Wedge is Callaway's very best design and the most tour-tested, tour-validated shape in the company's storied history, taking wedge play to a new level. Control is one of, if not the most crucial element to excellent wedge play, and thanks to Spin Gen Face Technology, the Opus can execute shots of the highest difficulty. Spin Gen consists of three crucial elements on the face, including a tighter pitch with more grooves, offset groove-in-groove technology, and a new aggressive face blast. These cutting-edge innovations generate relentless spin on shots of any length, with minimal drop off in wet conditions or from heavy rough.
