The universal small birdie choke combo is 1/4-1/2 aka skeet/IC and Modified. With respect to large reptiles they have found 14+ft American Crocodile in the Everglades. That is well into man devouring category so actually your situation could be a whole lot worse. I'm not sure how aggressive such beast is in comparison to saltie or African Nile ones, but I sure as hell would not want to find myself bird hunting or fishing near one.
Jag, I'm familiar with the big American Croc in the Everglades National Park. He hangs out at the opening into Broad River Bay on the boat trail from Big Lostmans Bay. Every time I go by him I get the feeling he is wondering "how do I get the tasty food out of that big fiberglass container?"...Geo
