What sells the best?

Trying to figure how I want to focus my production. Would like to get some opinions. I've conquered all the easy sectors except sector 7. I'm level 21 atm. Should be 22 by time I conquer 7.

Hardwood and marble of course are always in demand, but it can get saturated at times. Coal also seems popular. I could laundry list some more but would like to hear what other people think.

Oh, and any suggestions on what goes well together would be welcome. For example, if I choose to export tools, selling bronze swords would compliment it well. I've held back on upgrading a lot of my stuff because I'm planning a tear down once I hit 22.

Thanks for the help.

Tools are sometimes undervalued, but this could change. Bronze swords are also sometimes undervalued but you can make a nice trade with them at the right time. Coal is probably the easiest thing to move, but you will almost always be competing with others offers. Things like iron swords or steel bars can be better since there is less people selling and you can sometimes set your own market for those goods.

I would suggest coals, though I'm not a coal producer, one of my friends told me that he sold about 20k coal a day, making about 500 coins.

One Word... Listen real close: BREAD

Bread, coal, wheat, tools and bronze swords can be quite valuable to lots of players.

Thanks for the replies. I still haven't decided on what I'll go with, but this has helped me narrow it down. I imagine I'll get the numbers crunched this week and start working toward establishing my primary industries.

This calc (http://ceo-economy.appspot.com/) has been very helpful in my planning.
