I would suggest calling benelli's tech support department and tell them what gun you have and see if they have any reccomendations. Some of these guys shoot all the time and would probably know more about your specific gun than a person that shoots a winchester or browning. We can only tell you what we use, but brand, choke material, porting, rifling, and constriction of chokes plus variations in loads can be different from one gun to the next. I have about 12 chokes for my 1300 winchester. I can say make sure your choke threads are lightly lubed and tight before shooting so you dont get a seized choke. Also check your choke while shooting to make sure it hasnt shot loose.
