I defer to your experience, but in my experience of innumerable D1, M0 and Night shifts at Heathrow, heavies are far more likely to roll long on landing before 0700. I believe the AIP actually says that use of reverse thrust before 0700 local should be minimised conversant with operational safety.
Luckily on 09R with the T4 noise restrictions, most BA heavies know that they have to come off at S4 otherwise they'll be vacating left. Even then they take an age to get off there (understandable, because it's a 140 turn off the runway).
amazingly talented, good looking and underpaid pilots
So you're saying the people I often escort on a tour of the tower are imposters????
