Agree with all comments already posted.

On the 767, if you do go for 27A/B you will be responsible for the exit as there is no longer a crew member at that door after the removal of the purser. So if you are not happy to take responsibility for it, as you will also have to in row 11 on the A320, then please do not pick them

There seems to be an increasing number of people not prepared to listen to instructions about emergency exit rows and you will be moved if there is any issue with that.
