I just got my first SBD skinny string(8 strand) for my ol Bob Lee Thunderbolt.I measured everything the way they said,got the string, strung it up,and had9.5 brace height first.So,I unstrung,unwound the string as much as I thought I could,restrung,and still got 9".With my old string I always ran it about 8".I shot a couple of arrows through it and they seemed fine,but then got cold feet.I would guess that I would still get about a quarter inch stretch after it would get shot in but this seems like it would still be too much brace height.Im thinking that I screwed up and had this made too short.My old,shot in b50 string measures 57+5/8ths,My new SBD is58".This is a 62" 57@28" bow.Any ideas?
