I've never kept corns but I do have a 3 y/o Cal King and a 2 y/o MBK and I love them both to pieces. They were a bit fiesty as hatchlings but they got over it quickly. They're both really sweet now and neither of them ever musks, strikes or rattles their tails. They both hit their prey really hard at feeding time but the Cal King will take sporadic food breaks. I give my kings a hot spot of 86-88 year around. I think they can be kept easily in tubs, tanks, wood or pvc enclosures. I'm not sure if you're open to other colubrids but if you are take a look at the Pituophis species of pine, bull, and gopher snakes. My bulls are awesome. They get a bit larger than kings and they're also a bit more active than my kings.
