He will definitely be just as nice! If you handle him like you handle your BPs he will be an absolute sweetheart... albeight a curious sweetheart! I've found that boas tend to be pretty nosey... they will try to check out anything and everything they can get to.
When I say he doesn't seem to have a whole lot of hoggie in him, I mean that his coloring is tending more towards a normal Columbian, that he looks a lot like a normal Columbian baby in general. Hoggies typically have orange tails, Columbians have redder tails. But, like I said, he does have that nice orange tinge to him... and that's Hogg!
I'm not understanding where you see the big difference in him and a normal Columbian? He's going to end up looking a lot like your typical BCI...
Also, you can find some very nice pastel boas online for pretty cheap... right around that $100-150 mark. JnJ actually has a very nice looking girl up right now that I'm thinking about grabbing.
