In old C 5DG is good if you don't mind not sitting near a window. Row 9 is exit with lots of space, but you'll be confronted with two toilets being used by 64 pax. Not nice on a night flight.

343 to HYD are old C. Nothing special about 343s with old C. Mostly all the same. Avoid the toilets and the last rows.
