Just to further muddy the waters, I tried the La Bella Beatle Bass White Nylons for a month or so last year. They sounded great, but they were simply too light. If you go for La Bellas, it might be worth seeing if the regular gauges fit the tuners. (Don't forget that a violin bass requires medium scale strings.)I don't know if the D'Addario strings will fit into the standard guitar size winding pegs on the Hofner. Maybe consider La Bella Beatles Bass Nylons for the Hofner. They have tapered ends for the winding pegs that will fit on a Hofner.
