The 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 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.
