I've used a Givi 52 Litre top case since I purchased the bike new. Now done 20,000 in 2 years, fun only, and wouldn't be without it. One note of warning, if you carry a pillion you may need to ensure you set the case a little further back on the rack to avoid it hitting the pillion in the back over road bumps.
Along with this set-up I've used both soft luggage and hard cases. The soft luggage was Oxford sports panniers. These fitted securely but the waterproof covers use to blow off so I put my clothes in waterproof liners when packing. Only real down side is the strapping on and off each time and the potential security issue if you leave your bike luggaged up and go on walk abouts. The big plus is low cost.
I know though use hard cases. These are the Givi V35 cases fitted using the sw-motech quick release racks. These are brilliant. Cases clip on and off, very securley in a couple of seconds, whilst the quick release rails take about 30 seconds to put on or take off. Easy and quick to put on/take off, stable at high speed, secure and comfortable for the pillion. What else could you ask for.
