Load of rubbish & 100% correct at the same time. Your statement really only applies to 11A & 11K which were noticably narrower and particularly in leg room. 11D & 11F seem to be the same width as the other C seats (and if they're narrower, the seats are so wide that it wouldn't really matter). I do like the11 D & 11 F seats, as your legs aren't forced into a narrow space beneath the seat in front - you have the entire width of the seat to spread out in as no seat in front. No window (so yes makes 11A/K claustrophobic) but doesn't really matter for D/F as you're in the centre anyway.

Now, having had several overnight flights on the 77W in various row 11 seats, and now a single o/n flight on the 380, I think my overall preference is row 11 (or even 12) on the 77W. Love the mini-cabin feel, service a lot quicker due to this and cabin quieter. Seat wider on the 380 but the 77W seat is hardly narrow!
