I am currently running dual scimitars or scimitar amd blades sword. The game tends to decide for me which shows up in my right hand. As for my reason, they are the best I currently have available; my character is a redguard; CURVED SWORDS.
Generally curved swords, like Blades Swords, or Nordic. I haven't done Nordic yet, but I will on my Dunmer.
War Axes, too, on my Nord males. I'll switch between two Nordic War Axes, and a Nordic Sword and War Axe. For roleplay, looks, and damage. Because he is the Nord-iest Nord that ever Norded on Nirn. --- "Mistakes are just a part of learning.

At first I used twin War Axes of the best quality I had available, but then when Dragonborn came out I fell in love with the looks of the Nordic blades so I switched over to Sword & Dagger. It's traditional for dual-wielding plus is fast as hell. --- Hey there, sweetroll; I just cast Oakflesh... if you know what I mean.
