Atmos Rear Height Question

I know, another Atmos Question...I just bought a house with a nice big loft area, it's 14x22. I'll be using the front half of the room for my theater, so like 14x11. This means that I have the entire other half of the room behind me where I can put speakers and should get great dispersion coming from the rear or height. I'm getting an Onkyo TX-RZ800 and can't decide what to do with the 6th and 7th channels. Currently have Rti 8 fronts, CSi A6 Center, and FXi A6 for surrounds.

So...for adding two more channels for Atmos (can only add two so 5.1.2). Should I do in ceiling above the couch (option 1) or should I put speakers in the top corners of the wall behind me(option 2), so they would be like 10 feet back from the couch and four feet above listening position? Photos of the room are below (listing photos, not mine as it's not furnished yet). The couch will be perpendicular to the closet door and existing couch you see in the photo. Front of theater setup will be where the existing TV is in the photo. In the photo of the rear of the room, I put in circles showing where they would be if I went with option 2. Please let me know!

Hi, congratulations on the new house. The optimal location for the Atmos speakers is right above the listening location. You may not get the full Atmos effect with the speakers behind the listening position. You can possibly try a temporary hookup there to see how it sounds. Enjoy your new receiver. It is a great unit.

Another vote for option 1: height speakers above the couch (though it would be better to cheat them 3-4 feet forward, since our human hearing is better in front of us than behind us, it will make the height effect easier to hear).

You might find it helpful to read some of the documents posted on the Dolby Atmos website. Recently they have been changing their recommendations, on the height speakers, and leaning towards installing Atmos modules on top of the right and left speakers to reflect the sound off the ceiling. This gives a more diffuse sound for these speakers.

This is another option, if you have a room that would work for this type of configuration.

Ditto @sdurani , if you have a choice, always opt for TM positioning in a x.x.2 setup.

So as I continue to research I find a lot of people saying they really enjoy 7.1 if you have ample space behind the couch for diffusion. Should I go that route instead of one pair of Atmos speakers ( I know two pairs is generally recommended but this receiver won't do it)? Would 7.1 be a better use of time and $$$ for the way my room is laid out since I can't run the recommended 5.1.4?

I don't think they are changing their recommendation saying that Atmos upward firing speakers are better than actual ceiling speakers. They just understand that the upward firing speakers are probably going to be more popular do to ease of installation.
The system is made to work with actual overhead speakers, so that is going to be best.
