I love my tank and tail bag setup for weekend trips on my SCG. The Cortech Super 2.0 18-Liter Tank Bag (strap mount) is the largest tank bag I could find that doesn't interfere with the handlebars or riding position. Of course, you can't lean forward and tuck behind the flyscreen.
I have a Cortech Dryver Tail Bag because it fits the lines of the bike and doesn't hang over the sides of the seat. A drooping, shifting tail bag can be an unpleasant experience.
A weekend trip pretty much all I have time for, so I don't have any saddlebags.
