Aspen Bedding for Beardies?

[Bighead]

I'm pretty sure I know the answer to this one, but thought I'd check anyway. Would it be a bad idea to use aspen shavings with beardies? I use them for the rest of my herps and mice, rats, etc. so it would be convemient. I either hand feed crickets or put them in a bowl they can't get out of so they won't get lost in there. I also use a Reptarium and sand would get through the mesh. I'm using newspaper and/or paper towels right now. I'm assuming it's a bad idea, but I've never seen it cautioned against. Impaction? Thanks.
