I've done this trip about 8 times this year. What annoys me the most is that the menu was identical........not much to look forward to after the 4th odd time.
I agree if you're larger in size (not necessarily height) these seats will be an issue in terms of width at the shoulders, and the general privacy is nowhere near as good as a window CW one. BUT, everyone has aisle access, and the lack of privacy in some ways actually leads to a more spacious feel in some ways compared to the kind of "battery hen" feeling on larger CW cabins. But I still prefer CW.......!
Oh, but for "feetroom" on the 764's it's row 1, row 1, row 1.....the bottom half of the coffin is much bigger as it's a hole cut in the bulkhead not the seat in front
