I have two... Joe Rocket Manta It's a smaller tank bag, but works just fine for a day ride. Can hold a couple bottles of water, but will probably not handle the liner and tablet PC. Rapid Transit (not sure of type) This bag will do exactly what you are looking for, has backpack straps, lots of zipperd storage and fits on the Gen 1 FZ1 no problem. Rapid transit has many different size and shape bags, I would take a look on the net, or if you are near Roush or the Pony, both have good displays and choices. You may want to look at getting a smaller tank bag and medium sized tail bag...I can carry anything with the combination.
