Thanks,
as I mentions in the blog the basic idea is to have them on a "generic" basing system. I like the 4x4cm ones because gave me two ranks for infantry (much better appearance). They are intended for DBA (one base one unit) impetus (two bases one unit) and clash of empires and crusader rules (variable size units). Can use them also for Lost Battles, even if the scenarios included end with pharsalus and recently me and Phil had a discussion on how much the rules can adapt to EIR romans and roman vs roman battles.
I have reached the conclusion that one rule does not fit all and every rule give me one or two points I like so prefer to have flexibilty. DBA requires small armies and can be useful if you have few figures. Impetus, I like Impetus but sometime in 28mm I like the more skirmish feel of other rules and the ability to change formations.
