Ninerfan - I know this may sound kind of harsh, but I don't know any other way to say this: If you have followed this post and you're still asking those questions, then maybe you need to go back and read through it again. I could pick a quote at random from almost every reply in this thread that explains what you are asking. That said, I agree with you that this has been a fascinating thread with both sides of the issue addressed.
Peace.
