If you're using the bass plugged in then it's probably fine , I've got black nylon flats on my acoustic fretless, unplugged- dull and quiet, plugged -cavernous.[/quote]
+1 to that. If you only play unplugged then rounds are a necessity, and I would recommend Elixirs, but if you are plugging in then flats are an excellent choice.
