Which Ulm national units should I recruit?

Clarification:

I send my commanders out in squads of around 51 units, for a full squad. 30-40 crossbows. 5-15 black knights/black plate flails. 1 well equipped commander either black lord or lord guardian. Set the crossbows in back on fire at whatever you need to kill (you can set them in multiple groups). Set the melee units on guard commander. Put the commander immediately in front of the crossbows on (hold)x5 attack closest. A squad like this can defeat most indies. I would be surprised if 2-3 squads couldn't take any normal indep. force even on independent 9. Casualties are rare, and commanders rack up lots of kills on LI (I had a black lord with 160 kills!).
