Hi Alessandro,
I am glad to be of some help and happy to discuss these issues with you and whoever else would be interested. Speaking on the source - I found bi-lingua (lat./en) issue of Salustii:

Unfortunatelly my knowledge of Latin is zero, and as this is pretty old book, I can't say if the translation is good.
Catiline is said to have been with "detached party", moving arond the front lines. If you can understand better: "Interea Catilina cum expeditis in prima acie versari ; laborantibus succurrere; integros pro sauciis arceserre; omnia providere; multum ipse pugnare,saepe hostem ferire..."
I guess that it was kind of personal guards and best soldiers from his supporters. In game terms that can be medium infantry as it is strong enough to be and 'elite' part of his poor armed army and on the other hand less heavy than the regular heavies on the other side.
There has been two commanders on the flanks on Catilinian side but it it said that they died at early stage. Salustii names only Petronius as Roman commander.
The scale of the battle was relatively small if I am not mistaken, so probably there could be less troops on the battlefield from both sides. You have made it 16/18 units wich is quite a mighty clash.
I would vote for
- one auxilia and two lights less for Catilina (at least)
- medium instead of heavy infantry with him
- without another Catilinian commander
- one Roman commander
- instead of 4 heavies on Roman side - one heavy inf. with Petreus and two medium, lined in the centre. (the battle was won throught the centre)
However note that I am fresh player to this awesome game (less than 20 games) and I lack the experience to judge in game terms , so these above are more of suggestion nature.
Best regards and thanks for everything you are doing here.
