I have been doing some research for a while now on boas. I am wanting something that will get bigger than my BP, but not huge. I like the looks of the BRB and the Dumerils really well. I also like the BCC true redtails, but I think they get a bit big. How big do Dumerils top out at? BRB's? I want something that will stay under 7-8 feet (for the males). I know that all species have exceptions, so some general advise is all that I am looking for.
