The problem for me is muting with my right hand, not the picking. I started fingerstyle and moved to pick when Chris Squire appeared. After that, I played a little of both. Today, if I need to be precise and funky, it's easier to do with my fingers. If I want attack and there's not too much damping required, I'll use a pick. On my Hofner I use pick exclusively. So does McCartney these days, although he has used fingers in the past.
