Very well explained, Stephen, as usual.  I hope my Beginner Guide does as well.
and...Yes.  My understanding is that Matthew actually has it backwards.  In the boonies you want the WIDE1-1 to insure you reach the ocassional fill-in Digi.  With only WIDE2-1 any fill-in is mute and you are "invisible" when only covered by it.
