Best In-wall surrounds to go with ML in theater?

What are the best in walls (surround)to go with ML's in a home theater? I have conflicting info. on ML in walls?
They aren't "in walls", but have you considered the small Maggies that mount "on wall", and are hinged to lay flat when not in use and then fold out for listening. They are pretty nice sounding and are dipole like the Logans in front.
