Mutazu bags, at $299 shipped, represent the best value for money by far.
In addition to being stylish, they are quite large, and well built. We also (well, Patti my wife) found some very affordable inner liners that are a close fit and will do the job for us.
Their downfall has been their universal mounts - the frames supplied which the bags attach to are very robust and well thought out. The hanging brackets supplied to mount the frames to the bike are strong and pre-bent for an "average" installation, but to do the job properly takes time and thought. Well, it took me 2 1/2 weeks of mornings to nut it out and put it together, and so I share my work with you now. I reckon it would take 5 to 6 hours of not rushing to finish mounting them from scratch, not including electrical wiring.
It also takes a few additional parts, like spacers, T nuts and bolts (about $35 worth), in addition to the pretty good set that comes with the kit, plus an angle grinder with cut-off and finishing disks, a 10-12" adjustable wrench and a can of satin black touch up paint.
To me, mounting bags up high and angling them to match the grab handles is just not on. These are set straight, in line with the frame, not the grab handles, and are angled down ever so slightly. You probably could adjust the angle up or down by about a 1/2", measured at the rear of the bag.
In addition, the bags need additional support to stop them from sagging inwards at the bottom under load, just like any other saddlebags. That is where most of the time and thought went. Some people mount them without that, and it looks wacky and is unsafe.
