I am also looking for detachable side cases for my CB1100EX. Thanks for this thread. I am monitoring it closely and look forward to following your example.
I do have a SW-Motech Top case that I like very much. I used the rear luggage rack to mount the top case more elegantly than my friends at SW-Motech recommended.
They also offer side mountable, detachable cases but it is not clear to me if they will work with the beautiful rear luggage rack we both like. Thought you might like to check out these links. I am considering buying them too along with the permanent mounts to see if I can machine/modify everything into a presentable setup.
