Some more ideas if you're confident and have the figures...
- Take an Early Hoplite Greek army of Asia, Sicily or Italy (I think they're the ones). This is a version with Irr Sp (I) hoplites, but also some useful numbers of Cv (O) and Ps (O), and make sure you get the baggage as well. Take three similar commands and employ Wall of Carp (sic) tactics. Rely on low aggression to make you the defender, and make aggressive use of terrain to break up enemy position and support Sp from woods with overlaps.
- Use stratagems boldly. My impression is that a lot of people still don't anticipate their opponents' use of strategems. Always take Scouts, and consider using other stratagems like Exaggerated Numbers and Ambush to confuse your opponents.
- Be aggressive on the table. No matter what you face, push forwards to get into combat. Deploy the hoplites in three ranks (maybe four) and push forward into combat. Keep the baggage and general safe, and your hoplites will be able endure massive casualties while taking your opponent down. (Advice perhaps not encouraged when facing warband armies - but most armies aren't warband-based!) Brawling tactics can be a lot of fun when you have the numbers.
