SesameCrunch, is this the Moulton day bag that you have below the seat? How do do like it?
I have the full size rack but it is a hassle to put it on and off so I am thinking switching to using the day bag and leaving the small tray on all the time.
Another option is using one of those under the saddle bags like this one

BTW, I like the color of your bike and the leather color of the handle bar grip complements it nicely
