Nice tail bag

I appreciate the larger tail bags and they look cool and functional although...I use the Triumph Panniers and the Triumph backpack they gave me when I bought the Rocket. It fits the larger Tampons Erik recommends and light clothing, shoes. My Rocket doesn't look as outfitted or admittedly aesthetically pleasing as some on here but I'm poor (maybe just a tight wad) so the backpack is fine. Am I the only one that straps a backpack on the pillion seat or rear rack along with the Triumph Panniers?
 
They didn't give me a backpack , they didn't even give me a discount on a
helmet. Stingy Canadians ;-)
