I agree angryrat - this is all about workload and no one seems to be talking about it.
EBA9, love it or hate it, binned 4 crew night credits but 145hr to make up for it. This 160hr(++) divisors with no 4 crew night credits is madness; and I say that without even referencing the nature of the flying you need to do for LHR/JFK direct.
Madness.
