I'm not sure what you mean by "BIG" in your want list description as there is long big and thick big. Every Dumerils boa I've seen has been 5.5-6 feet and pretty thick. When I say thick I mean not a real easy to handle shoulder pet. Having said that I am NOT any type of expert on Dumerils boas. But even if you had a 7-8' jungle carpet that is considerably different than even a 5 foot boa with the thicker type build. However, it sounds like the carpets can be a handful as HoFR stated, and are more squirmy during handling. 14 bites in 2 minutes seems like something I'd rather pass on. Great display snake IMO and I almost went that route. I also almost went the Dumerils route, but thought a BCI/BCC would be about middle ground for me. Slightly more active than a Dumerils and Royal, though I'm sure that can be argued/debated.

Dumeril boa have some of the nicest natural patterns I've seen.

Personally I think you need to find a few of the mentioned snakes as adults, handle them and see what makes you smile.

If you ask here you will get die hard fans for each type of boa and 100 reasons they love them.

Smart people just get at least one of each LOL! I'm not clever enough to convince my household members that I NEED a dumerils, a carpet and a few more BCIs LOL!

But you may be the clever one,,, ya never know.
