MITSUBISHI FUBUKI IRON SHAFTS
Introduced in 2011, the Fubuki iron shaft is a member of a family of shafts from Mitsubishi Rayon that include driver, fairway, hybrid and iron. The EI curves, by design, are quite similar. With the current buzz created by top PGA tour players using graphite iron shafts, it is easy to forget that premium graphite has been around for quite some time. The Fubuki AX irons shafts are designated 375, a 75 gram shaft and 425, a 85 gram shaft. With an installed price of around $120 each it was never that popular. Distribution is through Mitsubishi authorized club building distributors. In its limited weight range, it is one of the smoothest shafts available. The quality is outstanding, shaft to shaft profiles are consistent in the sets and the profiles are consistent among the three models.
The stiffness change from butt to tip is uniform, firming up mid shaft into a 12 inch long stiff tip. I see the Diamana Blue Board profile when I look at this. The firm bend profile in the tip is complimented by low torque. This creates good dispersion control in a light weight carbon fiber golf shaft. Radial consistency is outstanding, meaning no benefit to alignment. If your looking for a soft flex, light weight iron golf shaft with a stable tip, it does not get any better than this.
