you get less dust.
I don't get enough dust to worry about
Great grain cruch (no need for rice hauls)
I already get a great crush and don't need rice hulls
great run off.
I already get great runoff and never a stuck runoff
I think it is worth it.
You get about the same efficiency.
And I'm certain that for you and others it is worth it. But my point is that, as Kai says, for many of us there's no need for it. I'm all for doing whatever it takes to improve your beer or brewing process, but I also firmly believe in not doing things that don't make a difference. If you have problems you need to solve, conditioning is one way of possibly solving them. But carefully evaluate whatever you do and decide it if really makes a difference for you.
