Hi Honk...
@honkozzie,
Sorry that I cannot help you, but I did enjoy your thoughts about enjoying the B77, '...except for the seats and and the VNAV...' My guess is that you will adapt to the 77's VNAV quirks quickly, but I'm most curious about the seats. What part of the seat component is uncomfortable for you? You can bet that some Boeing designers and engineers are reading this space. Obviously, this is about Pilot Comfort, not some fluffy "F" Class seat. If someone does not like the B-Driver's Chair, the Boeing folks need to know about it. Blind yourself and your airline as necessary, but please... tell them about your issues. IME, they are very responsive folks.
