I think that waiting for CDZ complete RR before declare on Quat is a constraint more than a decision. We need 2 turns to fully heal our troops, 3-4 to have them in Mizar (so ready to be loaded) so let's say we can be ready in 5 turns. Of course i don't have a detailed plan for the invasion.
What i can say from what we can see *now* is that if we land a small stack (say a full EI) in the same turn we declare near any Quat city in their home-isle, they will be wiped from it. But i don't know what they will do in the next 5 turns (sorry, my crystal ball is out of order). What i can say is that the more EIs and frigates we can have in Mizar area, the better. But we must keep watched the 3 frigates now near the Pyra city and the 2 galleons now in Ama point city.
Forget to use slavery. We MUST continue on Emancipation to avoid unhappiness. If we start a GAge we can consider to move to Nationhood for 5-6 turns, no more. We can also consider to adopt PS for those same 5-6 turns.
Speaking of GAge, i agree that probably is worth wait 2-3 more turns, but no more. BTW, Ama popped a GS few turns ago and a GM last turn, so it's better to burn our 2nd GS on physics. Also we can consider to go for Communism, for the GSpy.
About Diplo with Ama, let me think something. Tomorrow i'll try to post a draft.
Last, don't congratulate me, Mavs' defeat is a team achievement. I just proposed a decent plan and actuate it with a good dose of luck (Quat uncoordinated invasion). BTW all those cannons were pretty useless, since i focused on them to answer to the cats. With indecent hindsight, less cannons and more cavs could have done better. But that's it and it went better than we expected.
