I found something on the Brunner site that I had read before, from the instructions for using spinning molds: "One mould half is completely filled with chocolate." Indeed the production video shows mold cavities being almost completely filled with chocolate. However the figures produced by these molds cover a wide range of sizes. The surface area of a sphere is proportional to the square of the radius, however the volume is proportional to the cube of the radius.
This tells me that as the size of the piece increases, shell thickness will increase. Naively I had thought shell thickness should remain about the same. If I completely fill "one mould half" of my SE-0110-G-L this will require 2,138 ml of molten chocolate. But we know the much larger SE-0166-G-B requires only 2400 g of chocolate. (And if I knew the chocolate density I could at least convert.)
But because I hope to have dinner sometime tonight I gave up and wrote Brunner to ask what weight of chocolate to use.
Contacting Brunner was a very sensible choice! If you don't get an answer I'll chat with my friends at Walker's chocolate here in Burlington who do a lot of spinner molds and see how much they fill it.
Here is a gratuitous picture of one of their spinners.
