I added a couple of straps and clips to a small backpack and turned it into a tank bag. I can still use it as a backpack if I want. I use it every day on my commute, carrying my lunch, camera, etc. Just picked up a medium-sized camera bag for my camera and strapped it to my sissy bar. Now I've got a handy little tail bag. Lots of options out there if you think outside the box a little.
