Two barrel sets - I never use the second set. Choke tubes - more of a pain in the butt than they are worth. I already have two chokes immediately at hand in my double guns which is why I have two triggers as well for instant change over. Skeet and Modified work just fine for all my hunting. And with the right loads my 12ga skeet gun did very well on decoyed Geese. Those same skeet and skeet chokes do just fine on 16yd trap and for all but the most extreme long shots at sporting clays. Chokes just aren't as important as many have come to think and most are over choking their guns anyway.
