Hi David Unfortunately the quote option doesn't work properly if I add my comments and change the colour of my text, so I'll post my comments without quoting anything. I don't quite understand what you mean with regard to your first sentence, or sentences, actually. " is in the past tense and "would" can be considered the past tense of "will" and thus fits the sentence very well.
