Designed to take your game to the next level with distance and dispersion, the JPX 900 forged gives you an extremely solid feel with the best combination of forgiveness and performance for a Mizuno iron. The club head is grain flow forged from 1025 Boron, which is thinner and hotter than the carbon steel used in the previous model. This allows the engineers to save weight in the head and distribute it around the face, increasing forgiveness. In addition, a new COR Tech Design is employed, using a multi-thickness face to increase ball speed on shots hit in the center or off center.
The key difference between this and the JPX 850 Forged is that the head is a little larger, with a slightly reshaped pocket and new "Power Frame" construction. This has increased the MOI by shifting around 21.5 grams of weight into the heel and toe areas, improving stability on off-center hits.
The new sound is also very pleasing, a bit more firm than the soft feel of the JPX 850 Forged, but it is not harsh or unpleasant at impact. The acoustics and vibrations are handled very well by the designers, making this a club that feels good even if you were blindfolded. Unlike some manufacturers, Mizuno does not offer a standard shaft with this product – instead they provide a wide range of options at no upcharge through a custom fitting (including the Dynamic Gold AMT, KBS Tour C Taper Lite and Project X LZ).
