If you don't want to be opportuned, you''d better to stick to row 60.
I was on 61 & 61 last 2 weeks ago and I have to stand up or at least to pay attention when the person at the window wanted to go out.
I found the space available to go trought the seat smaller than on 777 (I am talking about the distance between the middle of the 2 seats and the back of the seat in front of you).
Howerther, on row 60, you will have smaller TV screen (it's 10", same size as PV compare to 14").
