hello again,
we have used both panniers and bob, seperately and together. My husband always trails the bob and he really like it. Does your bike already have braze-ons for racks? If not, you may want to consider the bob. If it does, panniers are pretty easy to deal with. You could always have somewone weld braze-ons to your frame, but then your paint job gets a bit messed up. Bobs can hold a good amount of gear. If you do go with panniers, you might try to reduce your load so that you only use rear ones as having weight on the front can make for tricky steering at times.
