I have a Topeak Super Tourist DX Tubular rear rack and a MTX Trunkbag DXP with fold out panniers. I love the workmanship and convenience of the bag. Sometimes I wish I had gone with seperate pieces, but I can't really complain about what I have because it performs well. If I did it over, I might have gone with the MTX Office Bag since it looks and carries more like a regular soft briefcase, and looked at seperate panniers for other stuff.
