Since I have dual VP150 (the one below firing straight, belly-level and the one above slightly pointing downwards about a foot or so above the head), I would now tend to vote on the dispersion of dual-centers over a single M80. Sounds is still very directionnal to satisfy dialog and character movements, but evenly distributed accross all my seating positions.
You know, a comparison between a marching center and dual centers above and below would make an exlellent article for the Axiom newletter.
Edit: um, matching. A marching center would probably be a real dissaster.
