@Ronand......!
I recommend that you go back and read the posts on this thread, I realize that it is massive but if you just go back about a year worth of posts and read from there on, you will get all the information you want but most importantly, you will get a lot of information you didn't realized that you needed. Your questions for example, they have been dissected and explained over and over and over and over
over and over and over...!
