Rear Surround Help....

[brazosdog02]

Trying to finalize my build.

CMT-340 SE (Mains)
CMT-340 SE (Center)
Rythmik LV12R (??)
Denon X2000

Because of the setup, the rears will be pretty much above and behind the listener. Will the 200SE speakers be a better choice for this than say an in ceiling surround dipole that can be aimed?

Here is a pic. Red X indicate speaker locations that I can use. the north wall is an angled ceiling and doesnt get flat until where the north most red x surround is. That's why its there.
