LOWER SIDE SPIN
DIamana WB shows 44% less side spin in-house control shaft. Diamana WB’s control can be attributed to the the fiber used in the angle plies.
TECHNOLOGY: PERFORMANCE
Hacker’s Paradise reports: “As for performance, launch monitor and on course testing showed the Diamana WB was everything expected, living up to the high kick-point and low/ low classification. Off the 9.0 head, the ball flight was penetrating, and more importantly, the down range dispersion stood out while working with both setups.”
TOUR-PROVEN
In the last 20 years, Diamana has delivered over 300 total tour wins and 40 major driver-shaftsupported wins. Additionally, Diamana notched two majors in 2022, two in 2023, and one in 2024.
BOTTOM LINE: PLUGGED IN GOLF REVIEW
“The Mitsubishi Golf Diamana™ WB is a shaft worthy of the White Board name. It has the low launching, low spinning performance that higher speed players love but with a feel that’s miles from stiff or boardy.”

RPM AVG
Chemical’s MLAB testing of a DIamana lower-launching 6th Generation counterpart Diamana RB shaft provided a higher spin rate, just over 200 RPM.
TECHNOLOGY: STABILITY
Unqiue for a higher-launching shaft with with an active tip, Diamana RB’s torque remains relatively low overall versus other comparable higher-launching shafts. This lower torque value — more than 0.5 degree lower on average than an in-house control shaft, for example — is similiar to recorded torque values in both the 6th Generation white [WB] and blue [BB] profiles, making it an option for a wide array of golfers.
PLAYER-PROFILE
Who should play Diamana RB? Golfers in search of a greater launch angle and greater average spin rate in a tour-ready, premium shaft label should try Diamana RB at an authorized fitter.
