1. a nice O/U (my preference would be my 12 ga Beretta 685 because it is light and a great field gun)
2. A classic SxS (maybe my Remington 1900 in 16 ga or my Remington 1894 CEO)
3. A nice 12 ga Semi-Auto (either something tactical like my Beretta FP1201 or one for waterfowling like my Beretta AL390)
Just picked from guns I already own.
If the horse don't pull you've got to carry the load.
