What are the most common experiences with owning a rosy boa?

I have been in love with rosy boas since i first laid eyes on them, 2 years ago and have been contemplating if i should finally just go for it this year. I have been finding very conflicting opinions and care info about them though and would really appreciate what the majority of people's actual experience with having them is like. Are they really as excessively "food aggressive" as i keep reading about and how they are very fragile or "sensitive" to relative humidity passed like 30%? I'm very confused to say the least and any input from experienced owners would be great. Thanks everybody
