Mizuno JPX 900 Hot Metal Irons Review

With an impressive history, the Mizuno JPX 900 Hot Metal irons are back. We have seen the “hot metal” description on other manufacturers as well. It usually refers to the face of the club. The quality of the face to which it refers is thinness. Thin faces have been proven to work with high flexibility to provide better forgiveness.

They are also employed in delivering solid results with off-center strikes. One of the best things manufacturers understood in thin clubfaces is the fact that it opens up opportunities for weight redistribution. If you manage to free some weight from the front part of the head you can move it around to create a dedicated iron. Some manufacturers use it with the top of the head, some on the sole and some use the weight in both. Placing this weight on the sole of the head can increase the stability and speed of the iron.
