PE seats on LGW 744

Folks,
Couple of quick questions...
Would you prefer 18D - 18F or 19D - 19F? Heading to MCO in October, and upgrading to PE on way back. If there is a bulkhead behind the 19s, I think it might provide a nice cosy journey. But if there is no bulkhead, I'm guessing that the traffic in that area might be annoying. I'm nearly sure there is a bulkhead.
Also, as Flying Club members, we're getting free Economy seat selection 72 hours before departure. Do you think I've any chance of getting Economy upstairs?
Thanks in advance!
