If that's how YOU feel, then it's good FOR YOU to go unlined. Seriously. It's a personal choice. But all you have to do is look around to see that your own preferences can't possibly apply to everybody. My experience and observation, along with that of others, says that your opinion, expressed as a general rule, is just flat out wrong. As your personal preference, it's not wrong at all. As a general statement about what's better for everybody else, it is.
That is all I was trying to say. Is this a thread that asked for peoples "general rules", or is it just another useless opinion thread on talkbass? I vote for the latter...
