The PING i3+ irons come in two versions, the standard i3+ set as well as the i3+Blade set. Both sets feature progressive offset, including more pronounced offset in the short irons compared to their i3 predecessors. The offset makes it easier to square the club at impact to improve shot accuracy. The Custom Tuning port in the cavity is larger, allowing for greater perimeter weighting as well as dampening of unwanted vibrations for an improved feel. The Blade model has less offset than the standard set. To improve playability from different lies, PING reduced the bounce angles compared to earlier models.
