There are several "lines" of Pucallpa Peruvians, and several "lines" of Iquitos...they are both the same snake just from different areas of Peru.
I know of one breeder who has large animals from both examples and to boot he produces some of the prettiest availiable.
The BCC from Peru are known to get pretty large by boa standards and you really have to ask yourself if you have the proper requirements for such a large constrictor
Send me a private message and I will show you some links to check out which may help you determine what is right for you but more importantly what will be right for the boa.
Take care.
