I disagree.. I don't think it should be used all that much. It can give the song a good lift at some points, but overuse it and it becomes flat. I actually think that half timing can sometimes be much better than double timing.
i didnt mean like the black and death and other metal bands use it... i meant like in a intro, outro or in the brigde.. IF that part is really strong and kinda fast, a double drumm thingie would mean the world to it. in my eyes.
he uses it alot live actualy, in the outros when he is banging everything insigth :p
