I just played my first game of DR recently using my Black Numenoreans and it was spot on, this will now be my go to fantasy game for battles of that scale (mass battles will still be handled with KOW).
That's pretty much my conclusion as well. Between Song of Blades, Dragon Rampant and Kings of War, I have found my triumvirate of Warband, Platoon and Company/Battalion level rule sets. It's kind of a load off the mind to need to keep looking.
Not that I'll stop, but now it's more of a casual eye-kept-out rather than a long search for rules that I can genuinely enjoy.
