My reasoning is, I wanted something that I could use for both my BPs and the rats.. but I do like the way that the newspaper is so easy to clean out of the BP tubs.. however, it doesn't give them any cushioning or anything to burrow through. I really don't want to use anything wooden for the snakes; I don't like how the cypress would leave little wood pieces on them, and for some reason I don't like the scent aspen has.. but the CF seems like it'd work well.. I am thinking of it for my bred female BPs to offer them something a littlke cushy; not sure if they'd appreciate it, but it seems like it'd offer a little more security, not to mention a better humidity retainer for shed time.. wow, this thread went off topic!
