I'm curious as to why you say not always? My field guides mention this as a distinct field mark for downy woodpeckers.I get the impression that the bill is consistent with Downy Woodpecker. The Downy Woodpecker usually has a couple of black bars on the outer tail feathers, but not always!

What about this clue? http://www.sibleyguides.com/2011/02/a-new-clue-for-identifying-downy-and-hairy-woodpeckers/
Honestly, I looked at different photos of Hairy and Downy Woodpeckers on flickr and realized it is not easy to use this clue because the position of the head changes the feather pattern greatly.
Thanks for the explanation. There's such variation in other field marks that I was hoping that one was at least a constant... oh well!See the big Sibley (p.312) where it’s noted that Downies sometimes lack barred outer tail feathers & Hairies sometimes have them. Personally, I’ve seen at least one unambiguous Downie in Nevada with unmarked outer tail feathers.
Entertaining... Your rule of thumb for this pair is exactly the same as mine. But in this case with the opposite conclusionTo me, if there is any question whether the bills long enough for a Hairy, it's a Downy. My first impression here is Hairy supported by the lack of black markings.
I thought that Western Downies sometimes lacked the black marks on the tail but Eastern always showed them but i might have imagined it. Hairy for me
