I have this one and it large and in charge, holds everything I can think to carry for days of riding. Easily straps to my deluxe and is easy to remove to go into motel as a carry luggage with a good handle on top. It has a rain hood that I test in a full day of rain and nothing got wet inside the bag. It big enough to use as a backrest for the driver and has more pockets for your stuff than you can shake a stick at. Thumbs up on this one for me. I bought mine from Value Accessories, really good people to work with on accessories for the F6B
