I just took the leap to an Anthem AVM 60 processor. The 7 channels on the floor will consist of 4 RAAL equipped towers, RAAL Horizon center, and S2s in the rear. Are S2s or Lunas viable as height speakers, or would the increased vertical dispersion of a dome style be better in this particular application?

Some time back I tried S1s with NRT tweets as surrounds in a 5.1 configuration. I didn't like the mismatch and converted to S2s. I don't want to buy twice, will it take ribbons as heights to properly integrate with the rest? I'm thinking Lunas with swivel mounts for their diminutive size/weight.
