VSL Versions and Notion

I'm thinking of buying VSL (or some version of VSL) to use in my compositions; however, as I view the product sites, it seems that there is a wide variety of products to choose from. Which program(s) can be utiltized in Notion with the built in rules files? I see VSL Ensemble, Ensemble Pro, and Instruments in the rules folder for Notion, but I'm a little confused. I see that VSL Ensemble and Ensemble Pro are their own player, so do they also have a VST to select in Notion for playback? Also, I was under the impression that individual instruments were in the Giga format. Can Notion use it's rules files for the Giga samples? I see that you can buy VSL instruments one at a time; will those instruments fit into the Notion templates?
Again, I know that you can use virtually any 32bit VSTi with Notion, but I'm trying to figure out which products will take advantage of Notion's presets.
I realize this is the Notion forum and that these are specifically questions about VSL, but considering that I want to get VSL to work specifically with Notion, I thought I'd pose the question here first.
