Folks: I have a Mosley MP-33 with WARC (10-12-15-17-20). I have added a Mosley 40 to it. Mosley sent tar rope for the guy and stays. I want to replace it with Phillystrand. What I need to know is what is the stretch factor of Phillystrand? Can any one help with this? Please respond. Gerald Muller K9GEM GMuller885 at aol.com
