I kind of fascinated by both of them, but would get a banjolele in tenor (or concert) size first. A variation on that theme would be a Camp Uke style, maybe concert size. Or how about merging a Camp Uke with a resonator cone??
Actually, I would go for a Camp Uke before the Banjolele and the Resonator. I think I would like a circle for the sound hole though.
