I think it varies with every boa too, as the above stated they tend to have much stronger feeding responses, they are much easier to switch to f/t, and they rarely refuse. I keep 4 bps and 1 boa, and my boa has yet to refuse a meal, but he also has bitten me much more often (he's still a baby...most of them grow out of that). He hasn't struck at me in a few weeks so I am kind of excited. My boa moves much slower and seems not as clumsy as my bps. He can climb on me for hours if I let him, and they are MUCH stronger than bps. I just love my boa though, I really do highly recommend them as long as you're careful to not expose them to your bp collection, which I'm sure you are aware of.

My boa is a bit of a freak apparently, I rarely EVER see him out...he lives in his hides and really only comes out if he's hungry, or if I wake him up to hold him. Once he's out though he's very active and curious..not lazy like my bps lol.
