MOR's only achieve anything if the issue is within the airline concerned (and then it's not guaranteed).
For example, over the hump on take-off at CDG we came across a vehicle on the runway. He rapidly left the paved surface heading for the grass, MOR filed (+ ATC informed). The outcome? The French stated that there had never been a vehicle on the runway!!!
LTD has my vote, but then I was also a "LTD" with the same airline so my vote is obviously null and void.
