Aspen vs newspaper?

[Bobtard]

Mine are in racks, I prefer to use scott shop towels (the blue ones) because they are more absorbent than reg paper towels or I use unprinted newspaper. Inked newspaper will discolor the animal and to me when its soiled the inked paper smells like hell

Hmm, well smelling like hell is no good. I guess I should stock up on paper towels, as if the geckos don't use enough of them!
Are they any advantages to using aspen in a non-rack system? I'm assuming it's no where near as abosorbant as paper towels.
