Oh, congratulations! I am thrilled for you. I've seen their bullsnakes (I watch their videos regularly) and they are really beautiful - and well cared for.
I adore bullsnakes. They were one of my first pet snakes when I was a kid, and my father and I herped endlessly for them - we'd cruise around at night to move them safely off the roads and had an informal competition for years to see who could catch, photograph, and release the (a) biggest and (b) most hissy specimens.
They are bold, active, typically gentle (for many, all that hissing is just 'talk'), and fun to watch. I love my ball python, but I agree that you'll likely really enjoy the opportunity to have a snake that is more active and visible.
Cleaning up after a big colubrid is another issue entirely, but hey - we pay a price to have these guys in our lives, lol. Enjoy, and please do update with photos when the time comes.
