I've been hissed at and struck at by my hogs and my normal Bi (BCi). Boa babies can be nippy but mostly for show and strikey a bit, almost all grow out of it. both my hog isle I can handle without issue, majority of my boas I can handle without issue, sometimes they have an off day, any species can. The more you work with them the calmer they will be, same for most species. A boa that is calm with the breeder might get defensive in a new enviroment and be strikey with you when it never struck at the breeder, or could be strikey with the breeder and then the calmest sweetheart and never an issue with you. /shrug. there's no magic formula for it.
Clean babies are clean adults, speckled babies are speckled adults. Wild types of both, esp hog isle are generally speckled, people breed for 'cleanness' (low speckles) because they like the look. One of my hogs is highly speckled (more like a wild type) and the other was bred for cleanliness. I think the speckled ones look more 'pure' but both of mine are multiple generation cbb pure, it's just part of their normal variation (same in any boa locality).
Boas are awesome, males are generally smaller. I think you'll be happy with whatever you choose.![]()
