A Vantage (whether a Vue or a VantagePro) ships with a value in the EEPROM
firmware that matches its cup size. Unless you change the cups, there is no
reason to mess with this value. The wee_device utility option is there if,
for some reason, you have to change the cups.

To answer your question, the Davis documentation lists only two sizes:
small and large. If there's a third "Vue" sized, I haven't heard of it.
You'd have to ask Davis.
