Atmos in-ceiling speakers

[CD Fourie]

I'm adding Atmos to my home cinema experience, in a small lounge. Not sure how I am getting into the ceiling crawlspace, or what I might find there..
Surrounds are old Monitor Audio Radius, so I am guessing MA in-ceiling speakers should be a good choice.

Any advice or Do's or Don't or speakers to avoid or other brands to look for?
Or just share your opinion on Dolby Atmos or in-ceiling speakers in general.

Thanks
