I recently purchased a 2008 Martin Viper Longbow (new). According to Martin the string should be 61". The string that came with the bow is 60 1/4 ". When the bow is strung the brace height is 8 3/8" and according to the manual it should be between 7 and 7 3/4". The bow is 40#@28" draw. I know the brace height will decrease with a longer string. My question is has anyone had experience with the Viper and what length string do you use to get to the correct brace height. I am not comfortable buying a 61" string as I do not believe it will get me into the correct brace height range. Wondering if I should go longer.
