How to identify this generation
- Confirm the HL suffix and compare the head to Mizuno's JPX925 gallery.

- The HL 7-iron has 3° more static loft than the standard and Pro heads.
- The pitching wedge is 45°, compared with 42° in the other two variants.
- All three 7-irons list 37.25 inches despite different loft and head designs.
