I have both panniers in front and back on my Rans Stratus Classic. You can see a photo below. I like being able to take things in the front too, as it evens out the distribution of the load on the wheels.

This photo was taken on a self-timer, with the camera on a cement structure. It was on a cold morning commute, and I have my commuting clothes, lunch, and laptop on the back of the seat/rack.
