As Mitsubishi tells us, this is a return to the original RB, Red Board profile. With new material technology and an “active tip section,” translation, softer. I see the RB as a perfect fitting match to the 6th generation Diamana series. WB, firm mid, RB neutral mid, BB soft mid. Each of these three shaft are what I refer to as archetype designs. I have recently been given access to all shafts MCA offers. This is the first of many earlier Mitsubishi reviews that include the shafts not previously measured.
