What type of bedding/substrate do you use for your gravid females and why?

Nothing different from usual. At the moment, I'm using aspen shavings or shredded aspen. I've never had any males have any issues, either.
In the past, I've used newspaper. My only complaint with newspaper is that the clutch sometimes sticks to it, and then the paper adheres to eggs, and can grow bacteria in the incubator.

Really, thats the first time I've ever hear of that. Something to think about. Have you personally had this happen before? And if so what happened to the clutches?
