I'll just put in a word for Knog. I have Frank's Dog and it's a great pannier with the small alteration of a bottom hook (cut up a spare bungee cord and stole the hook). It was surprisingly hard to find a pannier with hooks and a shoulder strap when I was hunting last year. That said the options above look good.

It's certainly the trendiest thing I own. I am single-handedly taking down the hip-factor of Knog by owning one.
