Profile – The Miyazaki Dromos series is a brand new shaft series recently engineered specifically for the adjustable driver market. This is the 3rd line for Miyazaki and features some spectacular artwork from artist Dromos. This is the stock shaft for the new Srixon Z-Star Driver. Available in a variety of stiffness’s and flexes – there is likely a Dromos shaft for your swing. To get an idea on the flexes within each shaft Miyazaki has a patent-pending international flex code which they use to distinguish the stiffness of four distinct parts of the shaft: the tip, the mid-tip, the mid-butt, and the butt sections. This system assigns four numbers, each representing a stiffness, from 1 being an “A” flex to 9 being “XX”, to each part of the shaft. This four number code gives you a good insight into how each shaft performs for each of the four steps.
