Bismark is tempting. Stonehenge would be nice with 2 charismatic leaders, and the border pops are as good for defence as any protective trait (which only helps one leader, and only one type of unit).
On the other hand...
- Stonehenge could just go to whichever team has some luck at the beginning. If the other team gets the chance to settle on stone, or has an expansive leader with 4h start, and / or in a protected 'middleman' position, etc.. Bismark's Industrious trait could basically end up contributing nothing.
- Whereas we know the protective trait is going to get lots of use...

- Also, picking an industrious leader makes our strategy somewhat transparent... We're just asking for Mali to get an early choke from whichever hostile nations start near her, whereas we'll be guessing which of their civs might be going for Stonehenge..
So I think I'm leaning towards protective Mali and just getting the choke on. If we can get Stonehenge as well, so be it, but hurting the other team hard and early seems like the safest bet...
BTW - attached is a test save with these settings all correct (Bismark for Mali, everything else as chosen so far) which can be loaded as a hot seat game for anyone wanting to get a flavour of these settings. All players are set to human so just retire any you don't want to play (after settling the initial city if desired) and the AI will play them for you as needed, so you can play as single player if you want to speed things up.
Also works as a pitboss game if you prefer - just load it up in the pitboss app. Password is
CFCftw. Again, after logging in as each civ, you can kick any you don't want to play (and / or claim them back later, which could be useful).
