Currently I am using just L/R and I find that I have to turn up the volumn quite a bit more to get good dialogue in the sound stage.
Then when some action takes place it is too loud.

I find with a centre channel I do not need the volumn up as most of the dialogue is coming from one speaker in the middle and more direct. The when the action takes place the L/R speakers handle the level more acturatly
