I've had Hardstreet, Triumph leather, and K-Drive (Cs4) bags suspended only with Easy Brackets. Leatherlyke has its own mounting but no underneath support.
Typically, the bag will need some form of support bar or you run the risk of cracking the bag. It needs something structurally to disperse the weight and force against the mounting points.
Edit; I use Ghost brackets for my hard lined leather bags. The Ghost mounts come with a plate that mounts to the back of the bag, providing the support I mentioned.
Not sure about hard bags, but I have the largest set of bags Viking makes on a set of easy brackets on one of my rockets that were loaded to the max during the 4,000+ miles of the last RAA. Worked just fine.
I have mitzy's removable backrest designed for he easy brackets and was looking for something to just mount when I want them and take them off when I don't.
Found some touring hardbags on eBay that looked great - just don't know how they would mount.
