Congrats on the Ortliebs! I have the backroller classics as well and LOVE them tremendously. After communting with carry-on-body bags for the last 15 years, I finally broke down and bought panniers. It is almost unbelievable how much I love them. They are plain black, but I have been looking at designs to spruce them up.
However, I am still not over the "oh my, I must be forgetting something" feeling because of the lack of uncomfortable weight NOT hanging off my person.
