I have a pair of Bredilis. They are pretty cool. I like them better than any other carpet I have owned.
Caging is not difficult for boas. I keep my adults in 4x2x1 PVC cages with 80 watt RHPs. Larger boas would need larger cages and higher wattage RHPS. The RHPs would have no difficulty heating the ambientm temp if yours stays between 70 and 74. I say go for it.
I also want a Black-headed python!!
