Everyone on here seems to be suggesting hanging high. From a different perspective I always requested a 6" or 8" clear space directly above the space required by the electrician for light and their installation (usually 6 to 8"). Never had a problem with high hats - the chances of your pipe actually occupying the space is slim unless you install center of hall. Duct and plumbers were all above sprinkler pipe, and since my requirement for a gridded flat system were minimal, there was never a problem. Nor did I have problems breaking around duct to get to the ceiling. With the new flex head extensions this should be even more acceptable for all since you won't be running your lines in the same row as the diffusers. If the project had different ceiling heights for large areas, piping would also break, for small areas not so much. If all trades agree on taking a specific dimension above finished floor and stick to it there are few problems that arise. It may have been unorthodox to you guys but it always served me well.
