FWIW, I'll make an observation that the window/aisle seats are the first to go. One reason, have vents and are cooler.
Just completed BKK-DOH-LAX (77W and 351). Window/aisle seats were first to go, then middle seats when OLCI opened.
If you like it cool, I rather have window./aisle seats. The 77W isn't too bad as there are centre overhead bins and individual vents. The 351 doesn't have either for the centre seats but have them for the side ones.
