I chose Wolfman Expedition Dry over hard bags for two reasons. First, since most of my motorcycle travel is long one day trips with occasional weekend trips I felt that the cost factor of Wolfman Bags compared to a hard bag and rack setup was more beneificial. But then again I ride a KLR - every thing we do is on the cheap
Second, the Wolfman racks for a KLR are incredibly easy to install/remove. Ther are three bolts per rack to remove and reinstall. Mounting/dismounting the racks takes about five minutes. So if I'm not going on a trip the racks are off in no time. Also, I felt that the Wolfman Expedition Dry set up cut donw on the weight compared to a hard bag set up.
So for the Wolfman Expedition Dry has held up remarkably well and I am satisfied with their quality and value.
