Dual Boxing DKs

I have two accounts and was thinking of leveling/unlocking a DK for crafting purposes. I figured if I was going to go through the unlocking process I might as well do it for both accounts at the same time. Any suggestions on what specs I should use? Having never played a DK before I figured blood and unholy would be good combo for the melee and AoEing abilities of those respective specs.

To be honest, as far as dual DKs go, any two specs will do just fine. I have run both Blood/Unholy and Blood/Blood and they both work great. If you run Blood/Blood, you'll kill stuff so fast that you won't even miss the AoE ability.
