Email Chad on here. He goes by LBR. He set me up with a really old recurve I setup. And also makes great flemish twist dacron strings. Just go to www.recurves.com His email is on there. You need to take a tape measure and measure the length of the recurve. I use a string to measure from nock to nock. And then measure the string. YOu probably want a string 3-4" less than that measurement. Depending on the bow, I would set the brace hieght to 7.5". I set the recurve I got to 8", to make it quiet, and the wife shoots that one and doesnt like string slap.
