For what it's worth, the Long Cage RD-6500 rear derailleur is rated for a 27T max cog. The Short Cage RD-6500 is rated for a 28T max cog. A couple people in this thread seem to think that a long cage means it'll shift to a larger cog, and that is not the case with the RD-6500. The long cage and short cage versions have the same parallelogram, which is the main thing that determines max cog. The long cage just gets you more capacity, which is the ability to take up slack. So the long cage version is a better choice if you are running a triple, but the two versions will take about the same max cog.
