Diamana_Ahina

 Mitsubishi Diamana ‘ahina

The successor to the Diamana White Board, the Diamana ‘ahina is a low launch, low torque shaft.  The softer butt allows players with a drop style transition to load the shaft at the beginning of the downswing.  The firm midsection is an important design aspect, delivering control of the stiff tip.  The new Multi Dimensional Interlay fabric from Mitsubishi creates a more stable and stiffer tip.  This stability is seen in both linear and radial directions.  The mid-tip profile is designed to deliver a low launch similar to the Diamana White Board.

The overall torque of the ‘ahina ranges from 3.3 in the 60R to 2.5 in the 80X.  The tip torque of this shaft is among the lowest we have measured.  The Diamana ‘ahina profiles are consistent from weight to weight and flex to flex.  The radial profiles are excellent; the shaft can be used in any orientation.

Diamana_Ilima Mitsubishi Diamana ‘ilima

The successor to the Diamana Red Board, the Diamana ‘ilima is a high launch, low torque shaft. The softer butt allows players with a drop style transition to load the shaft at the beginning of the downswing. The MDI fabric from Mitsubishi creates a stable, stiff tip. The ilima launches higher than its design partner, the ahina. The feel of the tip is noticeably stiffer than the Red Board.

Unlike the Red Board, the butt of the ilima closely matches the ahina design. The ilima is unique, bringing low torque to a high launching shaft. The ilima is a spectacular fairway golf shaft. I have sold countless numbers of fairways with the Diamana ilima. The reaction is always the same, ‘awesome’.

The overall torque of the ‘ilima ranges from 3.3 in the 60R to 2.7 in the 70X.  The tip torque of this shaft is among the lowest I have measured in high launching shafts.  The Diamana ilima profiles are consistent from weight to weight and flex to flex.  The radial profiles are excellent; the shaft can be used in any orientation.

Diamana_Kaili Mitsubishi Diamana Kai’li

The successor to the Diamana Blue Board, the Kaili like other shafts in the second generation of Diamanas has a stiffer tip and compensation in the low mid to maintain a similar flight to the Blue Board. The multi-dimensional interlay tip fabric, referred to in Mitsubishi’s publications results in smoother profiles. The Kai’li became one of my most popular the day it was introduced.

The overall torque of the Diamana Kai’li ranges from 3.3 in the 60R to 2.7 in the 70X.  The MDI material in the tip provides a very low torque, while the butt torque is relaxed to create more feel.

The MDI material in the tip provides a very low torque, while the butt torque is relaxed to create more feel. This design, a stiff butt, is well suited to a fast tempo, hard transition swing. The smooth transition to a relatively soft mid section provides a controlled release of the load created by a hard transition. This design is a classic found in many of what I might dare to refer to as game improvement driver shafts. This shaft logo has been used in a few off the rack golf clubs. The volume of off the rack clubs vs aftermarket shaft sales is not overlooked at Mitsubishi.  High torque versions of the Blue Board profile are available from many shaft brands, Mitsubishi included.

    can the Kai’li be used in any orientation?

    • An unqualified yes. I have measured many, many of these and never saw one that had over 2 CPM difference between hard and soft FLO planes.

        Thank you. I was wondering whether or not it was worth it to get these shafts SSTPured. I am glad I can install them in any orientation

        • SST Pured was a technique that is not used much any more. There are a few holdouts that promote it, it is a nice revenue source if you still own or lease one of the instruments. The value of shaft alignment in an era of rotating hosels is questionable. If it added value, it would say that the rotating hosel does not work.
          I wrote an article here, Radial Quality and Consistency of Golf Shafts a long discussion of shaft alignment.
          The shortest explanation of the process came to me by way of a major company fitting tech. ‘If a shaft would benefit from SST Puring or any other sort of alignment, it belongs in a dumpster not in a golf club.’

    I am looking for a new 3 wood and I’m considering the Ilima as the shaft installed in a titliest 915fd. I’m currently playing a ping G25 driver 9.5 with the ahina 70 X cut to 44.75″. I love this shaft in my driver. My driver swing speed is around 114. My question is will the Ilima launch too high? I tend to hit the ball high and I spin my irons pretty well. I will be hitting from fairway but also tee. Should I tip the shaft? Will this be a good pairing with my driver shaft? Any input or suggestions would be appreciated. Thanks

    • Tipping would not be a good idea. This shaft gets stiffer close to the tip. If you want flight control do that with overall stiffness and weight. You might try the 80X, untipped in your fairway. The Diamana R is much the shame shaft. To get a little lower launch, look at the new Diamana Thump Fairway series. Again, don’t tip, go for the 80X. Another similar profile with a little lower launch is the Fubuki J, it is available in an 80X as well. That is the J, do not confuse the letter on the Fubuki’s just as you would not confuse the color on the Diamana’s.

        Thanks for the reply. I’m looking at the Ilima 80X. Playing length 42.75″. I have no where near me to hit aftermarket shafts to compare. I have to rely on reading.. Which worked well with the ahina as I really like that shaft in the driver. My only concern is the Ilima launching too high but in wanting to put it in the 915fd 13.5* which is a lower launching head.

        Will the feel of the Ilima be similar to the ahina but with higher launch?

      • Jake Couch

        Do you mean don’t tip at all, or don’t tip more than the manufacturers recommendation for FW wood tipping?

  • Jake

    For a 3 wood that I use off the tee often, would a kaili in 3W and the Ilima in 5W make any sense? Would the kaili still launch high enough to hit from the deck when needed? Of course they are pros, but it does seem there are several pros using Kaili/blueboards in FW shafts.

    • The Diamana Red, now in its third generation, has evolved to be much closer to the Blue/Kaili from generation to generation. The difference being the butt section. The R/ilima has a softer butt than the B/Kaili. It is hard to say how you will react to that aspect of the shaft, you will have to find somewhere to try the two.
