I had 64K on 744 to LAS but chose the 372£ to F, didn't need the TPs, but the IFE on the old 744s is apparently terrible so I need the F service to keep me entertained.
I actually like 5K, I was on 1A on a night flight and felt cramped and don't get the fuss about it, 5A is probably bad because of the loo's behind you.
