I'm trying to set up a youth recurve for some children. It is a Ben Pearson from the 1970's, rated for 20 lb @ 22". It needs a string and I have no idea what length. No markings on the bow indicate the string length. The bow is 48" long. If I knew what the brace height should be on a youth bow, I can buy one the right length. Does anyone on here know what a normal youth bow brace height is? I'm assuming that its not 8" like mine. Any knowledge appreciated! Thanks!
