Mitsubishi Diamana BF-Series Fourth Generation Blue Board
Mitsubishi has released the fourth generation of the classic Blue Profile. Like the third generation B, it is made using the proprietary high density Mitsubishi prepreg, Dialed and Mitsubishi MR70 fiber. The fiber is 20% stronger and 10% heavier than conventional prepreg. New is Boron Fiber is added to the tip section of the Diamana BF. One might assume that is what the BF indicates. What exactly can we see in the shaft measurements between the Third Generation B series and the BF.
