Talk:Jump Drive

Must it be Lanthanum?

I heard of Vargr jump drives using Barium instead of Lanthanum. Is there a canon evidence of this? What are the differences, in functionem & in the rules?

Droptanks?

Should some mention be made of droptanks, as a possibility (I suspect a GM may or may not allow them, or may allow them for part but not all of the fuel...)?
