I use both BCY and Brownell string materials. People have preferences and both products are excellent. We also have a variety of serving materials that work with your nocks and string.
Strings are usually made with 2 bundles and an appropriate number of strings for your bow. String ends can always be customized for your bow tips and fast-flight materials are padded with a strand of dacron or polyester in each bundle. For example, a 2-bundle string would be padded with 4 strands of dacron in each tip.
Additional services include a double serving to minimize finger pinch.
