Shaft Selector Xpert (SSX) is a great shaft selection tool. It has more features and flexibility than any other on the market. You can search by shaft manufacturer, shaft construction (aluminum, carbon, aluminum/carbon), and shaft usage (target, hunting, both). You can also search the database for a specific weight range of a completed arrow (with your components), a specific shaft diameter, or a specific range of percent FOC. From an operations stand point it is easy to use.
