What are your cheapest core units to defeat Rome?

The world moved on. Arverni took Mediolanum and set a foothold in Italy. The risk of provoking Romani did not come and they stayed at peace for a few years, taking Segesta in the meantime. Arverni were busy taking remaining independent regions around Gallic homeland, particularly in Swabia/Bavaria. The Sweboz mishandled Belgic tribes who rebelled and were later subdued by Arverni chieftain, establishing favourite border on the Rhine. The Poeni were pushed further into Hispania where - out of desperation - they started war with Lusitani as well and - surprisingly - took some regions from them. As the time approched the year 240 BC and all the independent regions around were taken, Arverni feel ready to start campaigning against the Romani. However, the Romani still did not take Sicily, did not get Polybian reform, they still stick with Camillan units. So Arverni waited and enjoyed last few peaceful years ...

The Time of Bondsmen reforms came before 240 BC and curious thing happened. In the previous campaign, when the Time of Soldiers came, new barracks appeared and the old ones were still present but "damaged". I used to destroy the old barracks and got a lot of cash (high tens of thousands). This time, though, the old barracks stayed fully functional and I have to build a new ones. If I destroy the old barracks, I have to start building the new ones from scratch, i.e. from the lowest level. So I wonder what behavior is supposed to be the correct one?

Though there are so few new units in the Time of Bondsmen that the process of switching to the new barracks everywhere may not be worth the trouble. I have to say I like the way the reforms work for AS or Makedonia, where the new units simply appear in the roster among the old ones.
