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.
