Hi Jason,



That is a very nice gradiant. Don't you think quite a bit of that is due to the 1/2" EPVC/PVCX you use in your racks?



At that thickness acting as an insulative barrier in the back and with the natural conductivity of this material I'd think a similar rack made from 1/4" EPVC or any other 1/2" material would not have the same gradient as your racks.



Which brings up a good point that you elluded to in your post. The effectiveness of backheat vs. belly heat will depend on the design and material of the rack. Obviously the ambient temperature of the room and the species being kept is perhaps the most important consideration. (These last two sentences are targeted to the originator of this thread).



Lastly, the current phylogenetic evidence strongly supports that egg laying is the ancestral condition in snakes



That's a much easier question to answer than the substrate one, IMO
