super vinci steve

I just bought a super vinci with a 28 inch barrel. I'm planing on using it for duck and goose hunting. I do alot of jump shoot where the ducks and gessse are long shots. I was wondering if the full choke that comes with the gun is okay or if i should i get a different choke? The amo i usauly use is windcheaster 3 inch #2 and i have a case of kent 3 and a half inch #4. I probly wont use anything over double bb. I would like to get some good feed back please. I don't want to spend to much money becuase the gun already cost me $1500.00.
