I usually just go politics + mass infantry with vinci cause it requires less thought. Air Vinci require a lot of micro. Tho I do love using the fully upgraded scouts with all their neat bombs and mines and anti-personel turrets rocks.
I love making a crapload of them, then calling them in every few minutes as support for my infantry attacks. Those turrents and bombs fuck up land units and the mines will shred most air fleets. Plus OMG speed.
