IMO: Barley/Super C Audax for day rides/lightweight commute, Nelson Longflap for lunch-and-change-of-clothes commuting/CC touring, Camper Longflap/Super C for all-of-the-commuting-things and long CC tours/lightweight camping.
I use an ancient Nelson (no longflap; possibly marginally smaller than a modern one) for my commute/gym trips, and I wouldn't want anything smaller - a Barley's ok if only taking lunch and maybe a shirt. I use my Camper if I know I'm going to be picking up shopping etc. on the way home. If I had to pick just one for commuting, I'd take a Nelson Longflap; it's usefully bigger than a Barley/Audax, and doesn't weigh much more when empty. I use a QR clamp for easy removal and rest the bag on my rear rack; without a rack I'd use a Bagman QR.
