Surround help

[atcjeep]

Current setup:
Ascend tower and horizon for front stage, NrT. HTM-200 for surrounds. I have an Onkyo 818 avr, Sony 70" led TV and Sony blu-ray. I am mostly a movie guy.

I am thinking about doing some upgrading and think the surrounds might be my best bet right now. I am looking at the Sierra-1 with NrT upgrade for surrounds. Is this overkill or should I go with the 170's for surround duty or maybe keep my 200's? Thoughts?

I am also playing with the idea of dolby atmos and projector setup but this will be at least a year and a lot of convincing on the wife to rip the ceiling open.

Thanks for any input!
Tony
