Ping i3+. The Ping i3+ Series features two different models- the i3+ and the i3+ Blade. This model is designed for the player who needs the forgiveness and consistency that Ping Irons have offered since they popularized perimeter weighting in 1969. The optimum offset which progresses from the short irons through the long irons, squares the face at impact for additional accuracy and optimum trajectory. Both models feature a leading edge which lowers the face surface for easier movement through the turf and more consistent ball contact. The leading 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 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.
