The theme for Mizuno’s new JPX-850 irons, which are cast and not forged, is added distance without sacrificing accuracy.
Mizuno hardgoods research and development manager David Llewellyn puts it this way: “Simply increasing ball speed is not our goal. Making it happen within a manageable head size is the real challenge.”
Llewellyn likes to talk about the presence of feel and workability in these irons, which are the longest in the Mizuno lineup.
Still, the difference between the JPX-850 and the new JPX-850 Forged is clear: The forged iron probably will appeal to better players who like the forged feel, while the cast version has a slightly firmer feel and is all about that elusive combination of distance and forgiveness on offcenter hits.
It’s interesting that iron lofts in JPX-850 and JPX-850 Forged are identical. For example, the 4-iron is 22 degrees, the 6-iron is 28 degrees and the 8-iron is 36 degrees.
True Temper’s XP steel shaft is standard in both models, although the Fujikura Orochi graphite shaft also is available stock in the JPX-850.
The retail price of the JPX-850 is $799.99 with steel shafts and $899.99 with graphite shafts. That includes eight irons (4-iron through gap wedge). The availability date is Sept. 19.
