OK...there are several threads on racks and panniers and such...but i wanted to be more specific (maybe ....at least to me it is specific)

anywho...Arkel has a pack/pannier combo which i love the thought of cause i am looking into a combo-type commute (bus/bike)
anyone familiar with arkel or any products like this???

...and what are your thoughts of having a pannier on only ONE side of the bike (rear)???
