Default. Always default in Oblivion! ... The only exception to this (the ONLY one) is as my characters level up past 5.
Imps. They should be 1 or 2-shot creatures.

I mean...come on. I can't buy that a giant arrow piercing through an imp doesn't just kill it (like it would at the start of the game) So I'll adjust the difficulty downwards for that one exception, but otherwise i'm always a default duckie.
Mudcrabs (Horrid creatures): I usually just outrun 'em. Or some of mine will sneak past them, if they're in a dungeon with not much room to run by (and attract attention) Lady Saga uses them for target practice, occasionally.
...
horrible creatures.
