Best Multiplayer Modpacks for Civ IV BTS

[Jpinter]

Just curious what are the best modpacks for Civ IV BTS that have been tested and work till the end of the game. Some I've tried in the past include; History Rewritten, History In The Making, CavemanToCosmos, VIP, and a few others. However, depending on the version, I've gotten mixed results. Sometimes my buddy and I can make it through a full game if we're playing on a Duel or Tiny size map, othertimes, it goes out of sync right from the get go.

I'd love to find a few modpack overhauls so we can play BTS with extended eras, Civivs, better AI, and more leaders/civ/unit types.
