+Red made nowadays would likely be a mostly purple lens, so I'm not sure you'd be happy with that if you're looking for pure red.
Yes, it's shocking how Oakley hasn't been able to make Ruby a consistently red lens (except in the Frogskins), but fortunately, from my experience, there's a more or less even distribution of dark red vs. fire-like Ruby in the XS. You'll eventually hit one sooner or later. My dark red XS was bought in Orlando, so hopefully that'll end up being a good sign for you picking up another 2 locally.
