I just had my first experience with the studio pods on the 77HD...wow, it sucked! I could list a whole raft of problems...but, in short, it didn't lie nice and flat, width at the shoulders is constrained, hard to adjust seat when lying down, control panel for the seat was not-responsive and doesn't allow you to adjust as much as the classic pods, etc.....I don't know if I'd want to take an overnight flight with these seats again
