The Ping i3+ has optimum offset for players looking for forgiveness. They feature a leading edge which lowers the face surface for easier movement through the turf and more consistent ball contact. The lead edge and bounce translate into improved playability from a wide range of lies and conditions. The Custom Tuning Port (CTP) is larger to increase the club's perimeter weighting and allow for fine tuning the club's swingweight. The Ping i3+ thermoplastic insert enables us to achieve the precise tolerances required for building custom-fit golf clubs without grinding or other common club-altering methods which can affect the subtle features designed and cast into the club. The walls of the port help improve feel and feedback. The Notched and Flat-top Hosel has been modified slightly to improve the irons' playability and feel. A larger notched hosel provides an easier transition through the grass and allows for precise loft and lie calibration. The flat-top hosel helps reduce shaft stress for improved feel.
