Did I miss it or did nobody suggest Swift?

You hear nothing about Dahon becouse they sense you want something a little different, not so many posting here ride high end Dahons. Being a strong rider you may want to stay away from the bikes with long seatposts and long adjustable (telescopic) stems, typical for Dahon. I like my Dahons but it is not the first bikes I would suggest for you.
Take a look at the Dahon smooth-hound and the two dash models.
