Brendo, the multi-directional QS surrounds (I have QS8s) yield such an immersive experience (without giving up imaging precision), I think you'd greatly benefit from using the QS10s as the side/rear surrounds. If you can mount them up near the ceiling, you may find you don't even require the front height speakers. Mounted near the ceiling, the QS surrounds give a very convincing sense of height. Helicopter flyovers and the like are totally realistic.
