Anybody know of a complete fiver set like this, or is it necessary to buy the C string individually? What would an 'average' size be for such a string and where can I get one (flatwound)? I have seen a flatwound D'A .032 and a TI .033, but I'm guessing those are actually super light G strings. Even so, is it possible (advisable?) to tune a very light G up to C? I obviously need advice from an experienced 5er who is familiar with the E-A-D-G-C tuning concept. Please advise...THANKS!
