Ditto me, exactly. You will never notice any "gap" from 56 to 69. That would be a great combo.

You would have to pry the 17-55 out of my cold dead hands, because I love the bright f/2.8 in this mm range.
You will use it inside a lot so you need the wide aperature when you are not in the daylight.
You will use it for portraits, so you need the wide aperature to isolate the subject & blur the background.
And the good IQ is obviously going to be something you want for all shooting.
