Hi Todd...Greetings: I charge the same for all strings. $55.00. Figure out how long it takes to install a string, plus going out to the car to get a replacement. As my father use to say to me "If You Don't Ask You Don"t Get". As for string breakage....I have never broken a string. The strings break for many reasons, but none because of my tuning. Fraternally....Fredieboy from Jersey
