In this video I talk about the purpose of the bow string and cables. How often we should replace them. Things that can cause a string to fail. Custom strings vs factory strings. The fiber material I choose and why. One color string vs multiple vs florescent colors of string. Basics of how a string is made. Breaking down the actual fiber within the strand of material and the directions the fiber is twisted. Does the direction the string is twisted matter? How the direction the string is twisted causes a bare shaft arrow to cast a certain direction as it comes off the string.
