Interesting. What do you suspect is on the horizon?

It's boron, not new, old material used in making shafts. These pics were on mizuno's twitter page last week.

Mizuno is making a a new forged material that's more of a blend.

Well so much for the mystery. Haha.

JDM Mizuno JPX EIII Forged already uses this blend of S25CM + Boron.

I am guessing they are just releasing this in the States.

Your spot on, actually when they melt down the metal to make the rod prior to forging they put in boron or boron powder and it becomes a part of the metal.

How did each one of them perform differently? JPX EIII forged, EIII hot metal and US JPX 850. How should I pick?

I know Boron is hard and light (and somewhat difficult to produce). So what does combing with S25CM accomplish? Harder and light club heads? More feel? More explosive off the face? More expensive? ;)

It allows them to make bigger heads at the same weight as smaller heads.

I like that idea!

Guys are you saying that the 850 is the world wide version of the Elll, with the Elll being JDM?

I picked up a set of these JPX 850 Forged with Modus 120's in Stiff and Iomic grips in red and white.Here is a photo of the 7 iron

Japan is not going with the 850, not sure why.

Nice Irons Ash! do report back on how they feel.

FYI guys MP-15 was just released for some Yoro Craftin! No stamping options but you can change finish, grind, and paint fill etc..

Guys, so did Boron steel really do a better job or just another option. Between MP-H5 and JPX850( or EIII), how you guys would make the pick?
