"Hating" F on the 77A may be a little over-the-top. I respectfully disagree with the OP based upon numerous flights in F on the 77A and the 74A. Mayble I've been exceptionlly lucky, but I've never been troubled by crew-related noise or foot-traffic. I even prefer 1A. And while I enjoyt the overall more spacious feeling that the 74A offers, I like the new-car ambience of a 77A which may be only months (as opposed to 15+ years) old.
Too each his or her own. Just remember all those other carriers out there that truly can make you shudder.
