A vote for soft ones....
Good advice as always Patrick.
I'll add my vote for soft bags. Lighter, actually tougher in a crash, and they will absorb impact energy and protect the bike better. Hard cases pass most of the impact energy on to the mount frames, and then on to the bike. I have Givi's on one F650 and Jesse's on the other and I would only recommend Givi top-boxes. The side panniers have been pretty unreliable, coming off their mounts a couple of times and not reliably locking the lids. My last trip out, I lost all my clothes for the weekend. The Jesse boxes are very well made and strong, extremely close fitting and I would rate them very highly, for rigid boxes, but they are very expensive.
