Having flown BA a fair bit, I've managed to work out where the seats are myself, even in F. I like QR as a rule, though you have to bear in mind that most of the onboard staff are concerned at career limiting effects from any negative feedback at all. But unless I do something like start in Sofia or book RTW ex Cairo, the prices are double.
But if you like them, and your wallet doesn't mind, please do book them.
