What are the preferred economy seats on a 77P two-class regional 777? Here's what I can see on the seat map:

39A - is a bulkhead seat directly behind which there is a WC. This is not listed as an extra legroom seat.
40K - again is a bulkhead seat, but this time there is a cabinet between the bukhead and WC. Again, this is not listed as an extra legroom seat.
54C/H - exit row seats with extra legroom, but with a bank of 4 WCs in front. I just know people will be congregating here.

I'll be flying HKG-CGK and am tempted to go for 40K even though there's a bassinet not far away at 39G. Any thoughts?
