An addendum to my previous post:
Mempilot makes some excellent points.
The bag I use has an open bottom, because I don't care about whether or not it spills at the surface. I really only need it to get off the bottom and control my ascent rate, as the wetsuit expands near the surface it becomes un-necessary. Also with a HP100, I have enough ditchable weight to stay on the surface with no effort on my part, even with a full tank. I didn't think about it before, but if you are diving double steel 120's, an open bottom lift bag could turn out to be a very bad idea.
The whole lift bag thing is harder than it sounds. It took five ascents from the 40' platform for me to get it to work half-way smoothly. The first time, I over-inflated it and ended up letting go of it because it was dragging me to the surface pretty quickly.
