Did some research and found an excellent company out of Ontario building quality strings. Mean Moose Archery. Check them out on Facebook or call them directly at 1-647-409-2814. They have lots of positive reviews on Archery Talk and are very reasonably prices. Strings and Cables for my Bowtech Reign with speed nocks installed were $100 shipped to my residence
