Completely agree.

But after the first few go-arounds/excesses, I'd imagine the majority of guys would find a seat to 'protect' themselves from excess. This would make the 777 and MD11 seats that much more senior as guys wouldn't want to get caught up in the back and forth shuffle. This would push the junior guys down to the 'junior' seats in the 767 and set up the seniority list to be shuffled easily between 767 and 757 as needed with little extra cost.
