Currently using black code 18 full set. Im thinking of softening up the string bed because i dont want to hurt her arm. I was told by someone on here to try the x one biphase and the blackcode as a hybrid. I was just wandering do you guys think i should put the black code as the mains or the x one as the mains. These strings are expensive so i dont wanna waste any. Also what do you guys think about using gut with the black code. I an using 18g because i know its a little better for her arm.
