Planning on ordering an open back with a duel setup. That is two bridges and two nuts to allow switching between steel and some type of minstrel style strings. My intent was to get a short scale (25.5 inches), however I've noticed most minstrel banjos seem to have a much longer scale. So my question: Would the regular 26.5 inch scale be better for the heftier strings? or is a duel system just a bad idea? Needing advice.
