I think the new info makes a difference in the one gun restriction exercise. There seems to be an implication that a twelve gauge is available, and that it has some greater capability than the 16. In that case, I'd tend toward more open chokes on the sixteen. If it was framed in terms of wanting a super twenty, then in my mind, I'd lean towards more choke. A one gun restriction is truly a nightmare scenario, and then some.
