So I tillered my one bow to a 7 inch brace using a string I always use for tillering. The bow in question is 64" nock to nock measured along the belly. It's a R/D bow so I dropped 3 inches and made my new string to 61". Same as the tillering string. But now the brace hight is way to high. I'm using dacron b 50. Does it just need to stretch out or should I be making my strings longer?
