The base CBM mod should be listed as 'Conceptual Balance 1.6' complete, though 'Worthy Heroes 1.91 + CBM 1.6' should also work well. The "Indy Commanders Only" variant removes recruitable independent troops from all provinces, leaving only the commanders. This forces nations to rely on national troops (and is mainly intended as an AI balancing mod if i recall correctly).

Whichever CBM 1.6 variant you use, as long as the initial pretender design is unchanged, and each player has CBM 1.6 installed and active when they design their pretenders, everything should be fine.
