I see why you don't like this font, but I think I again agree with Jokuc. I'm not sure if this was his point or not, but it would be a fair bit nicer than what you're using in the nav bar at present, as it seems like it's coming out of nowhere (it only appears in the nav bar). Another thing with fonts is that Celestia Redux, where it is present, is in all capitals which is unessential and equally unappealing (IMO, mind you).
