Well. I still prefer to use axes or cav for flanks, so if they are not engaged (which they usually are) and I find that their current target yields little result, I usually just change target. There is always an enemy in a good positions for a face full of arrows :)

I think I prefer the NAs as frontline infantry in field combat (of cause, relative to the situation), they can thin out their numbers before they meet up with you and then the flankers smacks their backs with an axe (sounds almost poetic ) and you won't get a better armored unit in the Danish army before swordsmen and DFKs.

Swordstaffs are OK, but it's 4lvl militia (took me ages to get there, had DFKs way before them - AFAIR - might have been a little greedy on the taxation) and they have weak defense and no shields, so without backup they are a short story, even thou they might take a lot down with them.

As for Danish cav, it right that they have some unorthodox cavs (axes and maces @ Huscarls and War Clerics) but I think they manage the routing collection just fine? I usually supplement with Frankish knights and Crusaders for the high powered charge, and in late eras your stuck with the basic FKs and Templars, but again I don't see it as a big problem.
