Can one of you guys with both the VP150 and VP180 do a test for me please?

I do not want to give up my center arrangement of one under and one over my screen. I can't, no way in hell, hand a VP180.

I'm very curious to hear if the the two centers would play nice together. So if any of you guys who own both could give this arrangement a try (VP180 under and VP150 over the screen), and report back what your thoughts and impressions were, it would be appreciated.
