^ I'm agree too... spears can be a PITA if you only have horses. My vote is for Copper. Iron is more important, sure, in the long term (Cannons!!!) but Copper comes earlier and it's scarcer than Iron. So, if you get Copper in BFC, you won't have any problem with Barbs or early AI attacks. You can delay expensive Iron Working, while grounding your economy. Eventually you will get Iron, often more than one, in some of your by-then 4-5 cities. Or beeline for Maces (iron OR copper) and use them to take your Iron.
