Your pictures are so awesome! Some great rides you go on. Glad Betty is working out so well for you : )
I have a small black Specialized seat bag that has a zipper which allows it to expand to a larger size. With the tube, tools, cartridge, cell phone, car key, I expand it, although it probably could be adjusted smaller.
My friend has the Specialized Rib Cages Pro that are black with red accents. They look really nice:
