One of the foundational premises of Sub 70 Golf is that until we can improve on a prior generation's club, we will not release a new generation. The 659 CB Raw is the next iteration of our award winning 639 CB. The 659 CB maintains the same head size and offset as the 639, but with additional weight added to the bottom of the club to lower the center of gravity and add forgiveness on off center hits. The long irons (3, 4, and 5 irons) feature undercut technology, which creates a hotter face, better ball speeds, and more distance. The heads are forged and milled from a billet of DT-4 soft steel, which provides the ultimate in feel and workability. The 659 CB provides improvements in ball flight, feel, and shot shaping over the 639 CB, and is a workhorse that should be the choice for players looking for a responsive and technologically advanced forged iron. The 659 CB can also be combined with the 659 MB or 659 TC to make a combination set, as each of them are loft/lie consistent throughout.
