He has been wearing iron, and steel, will skip elven as the true Stormcloak/Elf killer that he is, and will then use the DLC introduced heavy armors by both Dawnguard and Dragonborn that use the Advanced Armors perk. I'll then skip glass until I reach dragon.
It seems a "traditional" Nord choosing to wear heavy armor should go up the left side. I just don't see him using Dwarven, Orc, Ebony and Deadric.
Anyone else doing this? Maybe I just realized this and everybody's already doing it, but I normally play light armor so I've never really thought about it from a heavy standpoint.
