From what I understand about Medieval military organization, knights, or heavy cavalry, wore the heaviest armor and rode powerful warhorses that were considered ruinously expensive. Even though knights were always the focus of every army, the cost of maintaining them was delegated to vassals, who armed themselves and a few nobles should they be called to war.
Byzantium, which evolved directly from the Roman Empire and did not experience the same decline as in the West, was able to maintain standing armies, due to more advanced social infrastructure.
So why do Bretons, Germans, and Frenchmen get to form standing retinues containing 400 knights? Could a single ruler even muster the smiths necessary to create the armor for so many knights, given the decentralized nature of domains back then?
I do not think that cavalry retinues outside of the ERE should contain heavy cavalry. Heavy cavalry should be levy-only.
Retinues have their place. Certainly, the king had men to guard his castle, that he didn't have to call from the fields. But heavy cavalry do not belong in retinues, not outside Byzantium.
