I agree with a point that Scoop made about QOL regarding pay bans. I personally have throttled back to spend more time with my family as a wide body F/O. If we did a pay band that moderated F/O pay, pilots in my position would be motivated to take the narrowbody captain jobs that we can hold to get the more significant captain pay increase (especially, in light of the new productivity that would erode the differences in QOL). So, if you see yourself as a narrowbody captain benefitting from a pay ban, consider the unintended consequence of today's QOL senior F/O's putting downward pressure on the back half of the seniority list's chances for upgrade to captain.
And more generally, it seems like less choice would be less better.
