We’ve taken two our most proven, time tested tour proven profiles – Blue Board and White Board, and Mitsubishi Chemical’s latest design and material innovations, to create the Diamana™ DF-Series. The Diamana™ DF-Series uses strategically positioned DIALEAD™ Pitch Fiber, and an incredibly strong hybrid prepreg that combines Mitsubishi Chemical’s MR70 – a carbon fiber material that is 20% stronger and has 10% higher modulus than conventional carbon fibers, with boron fibers to create our newest lower launching, stiff-tip profile. Strength, stability, and performance has a new name – Diamana™ DF-Series. Features: Combines time tested tour proven profiles – Blue Board and White Board, and combines Mitsubishi Chemical’s latest design and material innovations. Uses strategically positioned DIALEAD™ Pitch Fiber producing unprecedented strength and control during shaft loading and unloading. Utilizes a prepreg that combines Mitsubishi Chemical’s carbon fiber innovation MR70 and boron fiber, providing higher strength and higher modulus than traditional carbon fiber material. Designed to produce low to mid launch and low spin.
