i believei would start with the primos jellyhead,kicks,or rhino,and then go with some type of heavy shot ...such as hevi-13,remington HD,winchester Xtended range or my favorite nitros...however i do believe the kicks choke is for lead loads where as the rest will handle all but steel..also indian creek makes an awesome choke as well..as far as shot size it's totally up to you..somewhere around a .660- .670 should do just fine..and if you go with the nitros you can get by with a more open constriction than what most people would think..i would also shoot the three inch shells as well as the three and a halfs because i have found the threes outpattern the big magnum loads very often..so i would pattern both shells..or just go straight to the threes...hope this helps and if you have any more questions i'll try and help..almost forgot to tell ya to keep in mind that no two gun-choke combos are alike so what works for me might not work for youand the same exact setup..however it should'nt be hard to pick a winner frome the above components.
