i bend mine on the long string to about brace height,, and get as even as possible(keeping in mind it will look different strung)
if the bow is difficult,( or heavy draw weight), I tie on temp nocks(below the real nocks) to put a long string on ,, bend it to brace height with the long string and put the real string on the real nocks,,, I have a feeling your bow may be too stiff to string now,, but just guessing
