Damage is partially determined by strength. Umbra (1 handed) will do 25 damage when you have 100 strength and it has 0 carry weight (main reason I'm delaying giving it to Clavicus Vile).
I found out yesterday that the default key in fraps to record movies is also Oblivion's default quickload key. I had twenty of those 30 second movies in my fraps directory and after I get done watching all of them I might post a few. Half of them look like they are when I was trying to put a few things on shelves etc in the Bravil shack so they should have stuff flying across a room for no apparent reason.
