The Carradice Camper is a huge option, too, if you need more room.
The Pendle is so nice I just bought myself a new one... this is the old one.
What I use depends on the bike and what I am doing, I often carry a small rock climbing bag with a hydropack in the summer or use my messenger bag for lighter duty and all my utilitarian / commuter bicycles can accommodate my 3 sizes of panniers or are like my extrabike that has dedicated bags which can be removed and carried by their handles. I also have several handlebar bags which come in very handy.
