A little more about the Kriega gear. I ran a 30 in the center a 20 on each side and a 10 on top. I can't say enough good about this stuff. Once mated together I could take the whole group off the bike as one piece, I I needed to take them in my room at night. Bring them out in the morning, attach four straps and you're on your way. They also have replaceable waterproof liners that can be replaced separately if they ever wear out. they velcro into the top of the cordura bag. I did a little over 7,000 miles on this trip and the showed no signs of any wear.

With very little effort the hard bags could be removed while leaving the Kriega bags in place.
Just one used as a Tail Bag,
A close up of the attachment Hooks, Very solid. The bags strap to each other and you use four hooks like this to mount to the bike.
When I first got them I was a tad disappointed, they seemed overly complicated and the directions were minimal. But after studying them over a couple of beers the light came on, about just how simple they were to use.
the straps all have keepers for the extra, no loose straps flapping in the wind beating up your paint or getting caught in the wheel,
