The Tour Preferred CB irons combine a forged face with a cast undercut cavity to deliver the feel of a forged iron with the forgiveness of a deep cavityback. The Precision Weighting Port ensures consistent swingweight and optimal CG in every club.
Precision Weighting Port
A weight port permanently positioned in the center of the back of an iron head during assembly, the Precision Weighting Port assures that each iron in the set is of uniform swingweight while also ensuring that the CG location is precisely and optimally positioned in the center of the face between the toe and heel. In the past, clubmakers have installed cartridges of varying weight in the hosel to adjust swingweight, and by doing so have pulled the CG closer to the heel to varying degrees, resulting in a set of irons consistent in swingweight but inconsistent in CG location.
