I cant see any reason why you would want TO's in your race, With -30% income you shouldnt be building any CFs or LQs, Your Gross income will be tiny and your net income will be negative for most of the round. It doesnt make any sense for you to build TOs.
Even if you wanted to do the 7 TO start, you dont need TOs in your race; you take a race with TOs, start building them before round starts, then change your race back to one without tos. (But anyway I dont think you wnt to do a 7 TO start if you are SS. )
Your income will come from the resources you sell on the market- the only stuff you should build is MFs, RFs & RCs maybe farms too (possibly a few Ocs-).
Research at BORshould be 100% constrcution, you definitely shouldn't research ECO or Welfare with -30% income. Later in round you could switch to military & constr if you're planning on attacking much.
