First of all, if this has been covered let me know. I couldn't figure out how to word my search. Anyway, It seems that lately all of the music stores in my area are not stocking DR HighBeams 6string sets. I call and they always say " no sir but we should be getting them in any day now." NOT! They do have 5string sets all day long. My stupid question is this. Does anyone buy 5 string sets for their 6 string bass and just keep the old C string on? I find that it doesn't get as much use as the others and pretty much maintains it's brightness. Is this some strange freak like move or is it something that is commonly done?
