Having trouble deciding

so i can't decide on what substrate i want to use for my new 07s that are coming tomrrow. i'm using paper towles right now for my other two 06s but didn't know if maybe since they are younger they would like aspen. any thoughts?

I'm using cypress. Aspen wouldn't hold humidity for me.

Will they be going into your rack? I'd go with trusty old newspaper. I have 1 setup with cypress and 1 with newspaper....newspaper is GREAT! :gj:

I use paper towels, I like the look of the snakes contrast to the white towels....for humidity, I get two paper towels (soggy) in a container and set it on the warm side

Don't use aspen. They don't keep humidity at all, and sometimes can get stuck to your snakes mouth while feeding.
