I would think an le/premium design would be done first after some culling from the proto and then further bits removed for the pro. But I read Borg starts with pro and then adds stuff. I wonder if this has any influences in model preferences between designer games? A lot of Borg game owners prefer pro's as the addons are not that critical to improving game play. I don't know if the other school of design lend themselves to more preference for le/prems???
