One Microtraxion, one DMM Revolver, a couple of prusik loops, and assorted slings and krabs to make a functional system from whatever you plan on belaying to. And, obviously, the knowledge to use them to create an effective hauling system.
Pulleys are better because they eliminate a huge amount of friction, and thus make your hauling more efficient - or in practical terms, they reduce how heavy your partner feels while you're trying to drag their great weight out of a hole in the ground! And they weigh virtually nothing in the grand scheme of things.
