Darth Rage said:The link I put up is all I've ever seen in print, but I think you pretty much hit it - that you need to be seething with anger and rage. It definately makes sense. Maul was always full of wrath I guess, so he always had them. Dooku was always in control of himself and channelled his emotions well, so he never really boils over.
Okay, I'll go with it.
