^^This should be stickied at the top of the audio sub forum.
Personally, I've never had as much luck with the sub crawl as I have just trying different positions with the sub, leaving it there for a few tracks, and then trying a different spot. I would think that at least 75% of people, even on this forum, don't have a dedicated theater/listening room but rather make do with fitting a subwoofer amongst the rest of the living area décor. This means that there are only realistically a few spots which your sub can go to begin with, and I've usually liked the outcome the best when the sub or subs are in close proximity to the mains, as localization (which as you point out, subs can still be localized when crossed over at 80hz) and time/phase alignment become non issues. Buy a strong enough sub to pressurize your room, and you won't need to place it in the corner.
