mordormx,
FWIW here's a small cel snippet of Cassini's June 11 approach to Phoebe. It uses the "JACKcassini-xyz.ssc", "cassini.xyz", and the "cassini_v2.3ds" model.

Another way, and perhaps better in my view, to do this is to go to the NASA website that publishes the timeline (see website below). Just set your clock to just before the encounters. The published cassini.xyz tables look pretty close except in one case it looks like the spacecraft collides with a moon. The ring flyby looks so close to the real thing that the mission manager remarked he thought that someone was playing a joke on him and showing him the simulation when he saw the real images.
