I did find this tho



Now to the OP I used to use belly heat when I used newspaper as substrate because it was easy, but now that I use cypress I find it harder to control the temps through multiple cages, different amounts of substrate change the temps and the snakes like to move it around. Its not a big deal, but i find back heat just alot easier.

back heat is alot easier with substrate in my experience, substrate won't change the temps, I am currently working on switching all my racks to back heat now. The racks that are back heat, I have not seen any difference in their digestion. They still eat, digest, and crap just like normal lol.
I agree with this statment regarding belly heat and substrate it was very difificult to get a steady ready on my tubs when I used husks as substrate. I recently switched to pre cut paper liners for flooring and belly heat is awesome I enjoy having steady reads and believe that it would be more effective with digestion just as an assumption. an assumption that comes from understanding how the thermos work and that the heat would be more directly distrubuted with belly heat. but like i said just IMO.
