I used to use Shock Damage+Soul Trap, but lately I've not been bothering save for Soul Trap, and dropping even that after I get Enchanting to 100, since I can always buy a few filled Grand gems from the local magic-user to apply to my final gear. Then again I fight almost entirely from concealment, so damage enchantments aren't really contributing anything; they don't get multiplied while the bow's damage does, so they end up being a minuscule percentage of the total damage. There are very few opponents against whom I need more than 1 shot, as I play on Adept, and in those cases where I do need a second shot the damage enchantment(s) wouldn't have mattered anyway.
Now, if you're using Archery 'out in the open' instead then I could see enchanting it, since you're probably going to get hit and an absorb health enchantment can keep you topped off. How much armor and magic resistance you're packing is also a factor, since the more of both you have the less you need to steal health from your opponents. I went with Shock damage because very few opponents actually resist it and I can get decent numbers with it; I tried Absorb Health as well and was capped at a much lower value, which got me rather annoyed. As it turns out I should have used both together, but I wanted to have Soul Trap as well since I didn't feel like carrying a second bow just for refills, so that wasn't an option at the time.
Based on that, I would say that if you're going to enchant a bow for damage, you should dual-damage it and carry a second bow with just Soul Trap for refills; yeah, you're going to give up a little inventory space, but just one damage enchantment really doesn't do much against most opponents, even if it's Fire-based.
