Any 8BR is extremely inferior to almost any other setup due to the low population increase
Lead + Silver isn't great, but it's not bad either. You fit into this affluent population setup with lead, which is pretty nice.
Iron, Lead, Wheat, Cattle, Uranium, Coal, Gold, Silver, Gems, Fish, Wine, Furs
Iron + Wine is a princely combination. I would trade my resources of aluminum + rubber in a heartbeat for it, and get:
Iron, Sugar, Wheat, Cattle, Uranium, Coal, Gold, Silver, Gems, Fish, Wine, Furs
Some stats on all nations above 40k NS in CN with lead + rubber native.
I challenge anyone to find a resource pair the 40K NS+ nations of which have lower average efficiency :V
