I have a 12ga. Superposed. It is one of my favorite guns (because I shoot it fairly well). I mostly use it for sporting clays and occasional skeet. I wish I could shoot just one old SxS as well. I would take an old Superposed over a new Citori any day.
These are relatively heavy guns and soak up recoil well. The weight also helps with swing through. I do opt for something lighter for long walks or rough terrain.
The previous owner had thin wall choke tubes installed. Screw in chokes only make you feel better at the clay range. I would actually prefer fixed chokes in a hunting gun but, that's just my opinion. You could get the fixed chokes opened a bit maybe, depending on what you like.
