What level of science do we want to do most of the research at for Iron Working?

we need details first (i.e. time and cash)

How about as high a research level as possible to not lose money?

I agree with Pete ... so I am voting 100% which for me means max science without losing cash ... also don't forget to set slider to earn the max cash at the top science level

It's Iron Working - No one will sell it to us, that's for sure. We should research it at the max without losing cash.

Did not vote.
