In addition a Crown Step design lowers the CG allowing for improved launch characteristics. The Z F85 comes standard with a Project X HZRDUS Red 65 shaft and is available in 13.5° 15° and 18°.
The newest version also features a forged construction similar to the Z 585 and Z 785 irons but is built with a hollow club head and high-strength face insert that allows the club to behave more like a wood. What this means is higher launch higher flight and more distance for a wide variety of players.
However it’s also fair to say that the company’s handsome big sticks were somewhat known for being a bit shorter than those of some competitors due to slightly higher spin rates and a design aimed at more control.
