Generally all stings are twisted some. How much depends on the manufactures specs and what kind of string it is. E.G. Flemish strings are twisted until the desired brace height is attained. Some of my handmade Flems have 15 of more twists. The (factory) endless loop sting for the Parker seems to have 9 twist in it. Check to see how many twist your current string has and copy tha if it's the same king of string.
