I made a B55 string for a 64" Kenny M. longbow. I used the deminsions that l use for Dynaflight 97. When l put it on the bow, the bow collapsed to about 3" brace height LOL, I thought it broke.I tried to twist it to my normal brace height but it way to many twist.I made one 2" shorter and was able to get it to brace height. I must be doing something wrong. Don
