Biking I preferred to mount gear on the bike to keep the center of gravity low and maintain a feeling of being unencumbered.

A set of panniers and small rack for most of it, a small under-seat bag for the first-aid and repair kit and a handle bar bag, convertible to a fanny pack, for stuff I might want while riding. It wasn't like I was going far without the bike and it was usually incorporated into my shelter to hold a rain fly.
