MRCOTi_BradingMitsubishi Rayon has expanded the braided OTi iron shaft into a constant weight tapered shafts. This is explained in greater detail in the review of the OTi Parallel shaft The OTi shafts starts with a new form of prepreg they call Tow. The carbon fibers are arranged in bundles, the way a steel cable is made. The bundles are impregnated with resin and then woven into a braid. That braid bundle is then slipped over the mandrel. You might think at this point no spine. There is a common misconception that spine is caused by sheet overlap or welds. My experience is that it is the result of roundness or more specifically lack roundness of the shaft. In carbon fiber, that is mostly caused by outer wall sanding. The redial consistency numbers show below the measurement charts rates this important quality consideration.

Mitsubishi Diamana Thump Iron Shaft Review

Mitsubishi Diamana Thump Iron Shaft Review

This is the second release of a Diamana Thump Iron Shaft. The first release, in 2010, was eventually discontinued. At $160 per shaft, or $1280 per set of shafts, there was little interest. I am surprised to see the shaft again being offered. Perhaps PXG’s success at selling uber expensive irons demonstrated there is a market for ultra premium irons.

What exactly do you get at $160 per shaft? Much like an exotic sports car you get light weight strength. I am seeing equivalent steel stiffness with 10 to 15 grams less weigh. I am not referring the the R,S,X denoted on shafts. Those letters are meaningless ways to compare shafts outside of their own particular model. I am referring to area under the EI curve, the only functional method I have seen to rate shaft stiffness. I have to get into the 125 gram range in steel to see a stiffness match to the 2018 Mitsubishi Chemical Thump 105 gram iron shafts. These are truly exotic iron shafts at a truly exotic price. Unless you are comfortable with the stiffness found in something like a 125 gram KBS tour this is not a shaft you can load. But if you are, you have to see what happens when your clubs weigh loses 15 grams. Let’s take a closer look at the numbers.
