How is the legroom in the center bulkhead PE seats? Will a 6' person have any trouble stretching out? Currently deciding between 6EH or 9JL for a couple traveling together (other bulkheads already taken). If we can still stretch out and 6E can easily get to the aisle when 6H is sleeping, that would make the bulkhead an easy choice. Otherwise, 9JL would likely win for being more isolated. Seat width and a fold-out monitor are not a concern. It seems like the only comments I can find are for the side bulkhead, which has more leg room.
