So I spent a little time this morning reading into Atmos again. 7.1.4 or 7.1.2 is out of the question as not having a left wall forces me to mount my sides and rears to the ceiling. HOWEVER, it looks like 5.1.4 is a real possibility, as the surrounds are placed in the rear corners. I can easily place two bookshelves on stands behind my seating area without them getting in the way. I can then install the four height surrounds in the ceiling with the separation I need from the regular surrounds.

What do you think? Do you think 5.1.4 would be a better experience than 7.1? Have any of you experienced both of them to make a call? I only have experience with 5.1, 6.1, and 7.1...lol.
