IMO you should keep using your fingers, it's the way bass is supposed to sound to me. But listen, that is just my opinion, some people really dig that compressed pingy sound a pick gives you. I'm more into the fat sounds. .. .
IMO you are wrong. Don't listen to this bs.
It's best to develop finger and PICK style if that's what you choose.
Edit: Just realized how old the thread is. Oops. But my opinion still stands.
