Three Generations of Diamana White Designs Compared

There was little change between the first generation Diamana White Board and the second generation ‘ahina. Torque was unchanged, weight went down slightly as the era of higher density materials began. A stiffer tip area required an adjustment to the mid section of the shaft and a quicker loss of stiffness in the mid-tip transition zone.

In the third generation Mitsubishi Diamana W Series we see a huge change in the EI profile of the shaft. The Tip to Butt ratio, a simple indicator of launch tendency is unchanged, but the path there is quite different. The signature profile of the White Board, and its cousin, the Mitsubishi Fubuki Alpha, a mid shaft bump in stiffness is gone. What we see now is a profile that is similar to many shafts, a consistent loss of stiffness from butt to tip. The signature mid shaft bump is still there, albeit lower and softer. And, unlike previous generations, there is a slight but significant change in profile as the Diamana W series gets heavier.

UltraLight vs 50 gram models

A 50 gram version has been added to the line.  The Diamana W series 50 gram model have higher torque, consistent with creating feel in a light weight shaft. The tips are softer, and in looks much like a stouter version of the ultralight Bassara W series. The line between ultra light shafts and light weight versions of standard Mitsubishi models is blurred with the introduction of 50 gram shafts in both the Diamana W and Diamana B shafts. The Bassara models extend down to 40 gram models, but the 50 gram Diamana’s bridge the gap between the 50 gram Bassara’s and the 60 gram Diamana’s.

Radial quality of all the review samples was excellent. The Diamana W series is suitable for rotating hosels without any regard for alignment. As you can see from the chart above, it does not get any better than this.

Project X Hybrid Shafts Review

ProjectX_Hybrid_imageAt the time of this review the Project X Black and Blue Hybrid shafts have been on the market for several years. They represent classic hybrid shaft designs seen over and over from different brands. The Project X Black has a quick loss of stiffness tightening around 18″ from the tip and running from there into a long stable tip. This design is easy to tip trim into different loft hybrids, increasing the stiffness for the increased head weight as the lofts get larger. From my experience with similar profiles you will see a mid high flight with enough spin to create a nice drop and stop ball flight.

If you have experience with these shafts, you can take that experience to other designs.  Look at the bend profiles and reflect on the feel and flight of other shafts reviewed here. I have done countless fittings with hybrid shafts with these designs. If it is working for you, stay with it.
