Not that I am saying that alan s photo of a bike packing set-up crap, its a pretty sweet looking rig, but I do feel that it is on the heavy/bulk side, mostly because I feel that handle bar rolls and things strapped to the outside of a seatpackis a sign you are over packing. I don't currently have any photos of all of my bike bags on my bike, but I have edited a photo so show where my bike bags go, the packing list I wrote above using these bike bags leaves a decent amount of room in the bags for random crap I might pick up along the way.

A lot of people use a small bag(like a top tube bag) between the seat post and the top tube(just under the nose of the saddle) I find although you can carry more there, it restricts you ability to stand over the bike when stopped, so as seen in the photo I made a small bag to fit in the rear triangle space.
