For example, Glass Bows are the best damage inflicting light-weight weapons. Daedric bows do a lot more damage, but they are much heavier. Does it take more time to get a Daedric bow ready to shoot, than it does with a Glass one? Can I do more strikes in a given time period with a Glass greatsword than a Daedric one? I would test this, but I'm only on Lvl 15 so these weapons are hard to come by right now...
EDIT: I forgot to mention. I'm playing Laedon, a wood-elf sneak archer who wears light armor and lives with 0 scruples. Loves to steal, and is okay with killing for money. ;)
