The Mizuno JPX921 Hot Metal Hybrid Combo Iron Set replaces traditional long irons with hybrids, which is perfect, because Mizuno specifically designed the new JPX921 Fli-Hi Hybrids to replace your difficult to hit long and mid irons.  Many companies design hybrids like they would a fairway wood or driver, which is to say their efforts are primarily focused on distance.  With the Fli-Hi Hybrids, Mizuno focused on precision, and creating a deep/back center of gravity to help you launch it higher and land it softly.  After all, the goal of any iron-replacement should be helping you hit it as close to the hole as possible.

The hybrids transition seamlessly into the Hot Metal Irons, which are Mizuno's longest iron to date.  Mizuno achieved this feat by using two key pieces of the technology.  The first piece is a re-engineered CORTECH face, which is now 0.2mm thinner, and thinner means faster.  The second piece is a seamless cup face design which flexes and rebounds more, rocketing the ball of the face for explosive distance.

The stock shaft and grip are UST's Recoil ESX and Golf Pride's New Decade MCC +4 respectively.
