I'm looking to buy some luggage for a 5 day trip coming up. I'm trying to stay away from saddlebags, want something I can mount to sissy bar/back seat. I have been looking at the Kuryakyn ultra tour bag/daily tour bag combo, and also the Saddlemen 3500 drifter. Does anyone have any exp. w/either of these? Not sure about the space, haven't gone more than a day or two on a bike before. Any other bags? Thanks for any input.
