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.

    How would you compare this to the Tensei Blue or the KK XM? Love the Blue profile but trying to decide which is best.

    thanks!

    • The Blue and the XM are different. I have been fitting now for a few months with the Tensei Blue and White. The XM/XT have been a favorite for many years. The knee point of the Tensei Blue is higher up the shaft and the tip stiffness is firmer. This is subtle stuff. You have to try them side by side to determine which is a better fit for your swing dynamics.
