One thing that I noticed is that A is slightly forward of B so from the A seat you will have to look across and back (slightly) to see.
You may want to consider switching to the BC seats as there is a cutout that allows you to look over at the other seat (but since they are angled away from eachother you will have to turn your neck to look).
For the 777s, I prefer B-C seats when traveling together. I think it would be better for the OP.
