Have experience with hog island boas?

I'm thinking about adding a hog island boa to my pet collection. I have one adult honduran milk, and I'm looking to upgrade just a little bit. I love the hog islands because theyre beautiful and look very similar to a red tail boa, but are quite as big a little easier to manage (i think). I was just wondering if anyone has had any experience with these snakes and what you think about them. Also, if there are any other mid-size snakes that you would suggest, I'd love to hear about them.
