Several people post here recommending messenger bags for shopping and
carrying things. Some one gave me one as a gift about a year ago and I still don't get it. It seems awkward when loaded, it sways or feels like it brings my center of gravity up too high. My Ortlieb panniers have these shoulder straps for shopping and seem very steady when on the racks. I look at the bike messengers around town and notice several styles for hitching the bags- high 'n tight, low 'n loose, swinging or cinched with the belly strap. There seems to be no one preference among the messengers. Do the messenger bag advocates have any rules of thumb for using them that they'd care to pass on? Now I just use mine when I walk or I amplify the dorkiness of my utility bike by strapping the messenger bag to the rear rack.
