Two additional 'details'
12 and 13 Middle SECTION (entire section) in my opinion is horrible. Why? On most 777s I have been on there has been a COLD COLD COLD wind in those seats. Upon complaining to FA (have gotten several colds from such seats) was told 'something to do with the cabin air handling system at the end of the cabin'. I have also had the same issue at the last row of First in the center section.
Second decision to make is FEBO! Don't get yourself into a position (at the wrong end) where all that is left if the Vegetable Plate. I picked FEBO seats on DFW-KIX-DFW and it worked 100%.
