Last, but I am certain not least....
The placement of weight is critical as well. One diver that I know found the right amount of weight, but couldn't understand why she kept floating on one side. She moved some of the weight around in both the weight pouches and on the BCD. Weight in different places gives us different orientations, that's why you may see divers with weights on their tanks, ankles, different areas of the BC, around their neck.... (ok maybe not around their neck).
Oh, and if it hasn't be stated a million times already, practice practice practice. After 400+ hours u/w, I'm still working on perfecting buoyancy (it's excellent, but not perfect). Every dive is going to have different buoyancy characteristics, due to different states of mind. You might breathe (subconsciously) deeper or shallower on different dives causing different buoyancy issues. Thus, practice is the key: as you get more comfortable, you'll lose weight (off the belt that is) and use less air.
