My style?
I just enroll every single bastard I stumble upon, no matter his culture.
Of course he has to know how to use properly his weapons, so my troops range over Med-Inf and Heav-Inf. No Elite-Inf 'cause upgrade costs a lot and they easily die like other riffraff, so they are not convenient.
No bowmen: they are not usefull for my game style.
Few horsemen as I need them just to chase routed enemies and crush'em.
1-2 cleric to wash mine & and my mates' souls.
1 Companion wields personal banner and if I'm lucky enough to find an horn among the loot 1 companion wields an horn.
89 fighters overall as we often travel by ship.
