Hi i just strung my racket today with a Black Magic using the dropweight..oh boy, this string STRETCH ALOT. i was wonder if anyone string black Magic using a crankcase stringer? what happen when you reach your tension and the crank locks? that means the string is not fully stretch after your tension is locked. help? i dont have the crank machine yet but i will buy one and plan on using black magic string and i wonder how i would string this on the crank.
