Mitsubishi OTi Taper Iron Shaft Review

Mitsubishi 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.
