Textured kraft paper can be an acceptable floor covering in limited circumstances -- QT, small neonates that haven't eaten yet, snakes one wants a fecal sample from. Even though it is more snake-friendly than newsprint, it is a similarly a poor choice for reasons mentioned above.
I like reptichip for those snakes that need RH/moisture levels above ambient, and aspen chip for those that don't. Reptichip has the additional virtue of being a waste product (from coconut production). I'm trying out Jungle Mix for a couple snakes who could get by fine on either of the other two choices I mentioned, and I'm not sure I see any advantage, and JM is wickedly overpriced for what it is.
