The 757 should always have been put in the heavy cat once the problem was identified (20 years ago).
I'm sure the CAA baulked because it would have had a drastic impact on the movement rate at the flagship Heathrow.BA had nothing but 757s some years ago.Different now that they have been replaced with Airbus.
I treat them as a Heavy inbound and outbound.Ok it's covering your back,but you get skilled at that after 3 years in HongKong.
