hello. i have pulled my hohner bva (5 string steinberger copy), out of the closet, and started experimenting with it, but i'm not keen on the Roundwound low B string set that's on it. i want to restring it with flats, and from e-c. i am having trouble finding strings that will meet these exact requirements. (e-c, flatwound, double ball end). does anyone have any suggestions? I would also consider the steinberger string adapter, if i could find one. music-yo (gibson online) seems to be eternally "out of stock", and the mighty-mite site doesnt seem to have a steinberger section anymore. any suggestions? btw, although i prefer d'addario Chromes, i am not picky for this experiment, any strings that match my needs will do. thanks.
