I would have to agree with Andy that the AV system onthe 7900 is as smooth as the 372, and I had no problem with mounts breaking. The oiler on the 7900 was weak always had a 1/4 tank of oil left with the ajustment wide open.
The newer ones might be different, I can easily empty the oil tank on my 6401 before the fuel, surely the 7900 doesnt use that much more fuel to flip the other way.
