I too brought home some Navel Late oranges yesterday, and I noticed the Lane Lates also. The Navel Late is good, very sweet, but to my taste there isn't enough acid (I would almost say none at all...).
Here's a list of late navel oranges:

Valencia Late (going off-topic now...
) is also starting to appear. It's about time as until recently the juicing oranges on the market were all Salustiana, which are completely tasteless by now and (I think) way out of season.
That is not to say the Valencias are tasting great... I already juiced 2 bags of 3kg valencias. The juice of the first bag tasted good. The juice of the second bag was watery and rather tasteless... I will do another bag this mornig. I hope it will be good, otherwise I'm done with juicing for this season!
Blood oranges are gone now (still available in some places but not where I normally buy my oranges). That's a real pity. The Spanish Sanguinelli were my favorites, their taste was superb!
