How to properly play with the Incas?

So I kinda liked Incas a lot with most of their bonuses and unique troops and techs they offer...

Ik that lot of guys play tower rushes and all with the Incas... But I wanted to know how to play well with them from the Castle Age/Early Feudal Age...

I don't get Bombard Cannons or Cannon Galleons, which makes the ranged sniping harder and so yeah I'll have to pick trebs... But the navy is decent enough for a survival provided we get good teammates and stuff...

Usually I play cavalry based civs, so I go scout rushes or occasionally even Archer Rushes, but I've heard people tell me Eagle Rushing is not effective cause of how much time it takes to produce them... So my early feudal aggression is mostly Archer rushes, making my early game predictable and hence more likely for players to go skirms to defend against me or probably even scout rush me, so it might get hard... But usually I manage my feudal age decently....

In regular cavalry civs, I usually do a Knight Rush... I keep wondering what's a better rush in Castle Age with the Incas... Eagle Rush or Kamayuk Rush... Like I really like the Kamayuk stats and how they attack through walls... But I'm not sure how viable they are for a regular rush tbh...

And finally for Imperial attacks... My usual cavalry armies would be like 40-60 Paladins, 40-60 Halbs, then few Bombard Cannons/Trebs and few misc stuff like 20-30 Skirmishers or 20-30 Hand Cannoneers to fend off enemy infantry or Archery stuff...

But with the Incas, my army composition seems hard, mostly a hardcore infantry army like 40 Kamayuks, 40 Halbs, which makes it easier for Hand Cannoneers or anti infantry armies to take it down, I know I should keep Skirmishers or Slingers but managing it is easier said than done...

I tried Monk Rushing in Castle Age to convert a stable for fun, but seems pretty hard to perfectly execute it...

And finally, I thought alright lets check out some videos off YouTube like Hera to see how Incas are used, and I was surprised to see he almost didn't even bother using Kamayuks (I mean they're so cool) or Slingers (c'mon awesome anti infantry)

He just Eagle rushed with Onagers/Xbow rushed with siege...

I mean he's much more experienced so he'd know how to use it, but man he didn't even use Kamayuks or Slingers in his army... That made me wonder if I'm not using Incas in the right way...

​

So what would be the best ways to win with Incas and the best army composition guys?
Thanks!!
